Soldering iron for plastic pipes by hand. Soldering iron for polypropylene pipes from a boiler. Diagram of a homemade soldering iron for plastic pipes

Pipes and fittings made of polypropylene can be said to be in trend today. They are used for indoor plumbing and heating wiring and networks inside houses and apartments. The popularity of this material is primarily due to the ease of working with it. Unlike metal pipes, they do not need to be bent with a pipe bender, threaded or welded. All the labor intensity of this profession became a thing of the past with the advent of such material as polypropylene.
The main tool for working with polypropylene products is considered to be electric soldering iron or iron. In the factory kit it is equipped with nozzle sleeves for soldering pipes and fittings standard diameters. They can also be purchased separately. But there are times when, for some reason, a factory soldering iron is not available and there is no way to buy it, and of all the parts, only welding attachments are available. This is where a homemade plumbing soldering iron comes in handy.

This homemade product is one of those “blow, spit, and do the job.” You can literally assemble it on your knees from an old iron and a wooden block. With such homemade heater you will definitely save the situation and cope with soldering poly propylene pipes. And now we’ll show you how to do it.
What you need to assemble a soldering iron

• An old iron with a working heating sole;
• Wooden block, approximate cross-section 40x50 mm, length 40-50 cm;
• Four self-tapping screws, 3x14-16 mm;
• Sleeve attachments for a plumbing soldering iron with a clamping bolt;
• Power cable with plug;
• Electrical tape, 45 mm self-tapping screws.

The tools you need to have are: a drill or screwdriver with a Phillips head for self-tapping screws, drills with a diameter of 6-8 mm, grinding machine or sandpaper, paint knife, pliers and hammer.
Assembling a homemade soldering iron for polypropylene pipes
First of all, we disassemble the household iron, disconnecting the soleplate from the thermostats. We won't need the rest of the iron anymore.




Next we prepare wooden block. If necessary, it can be sawed, planed, or simply cleaned on an emery wheel, as the author of the homemade product did (photo).




To secure the bar, we drill several holes on the sole of the iron, in an area free from the heating element. The diameter of the drill should be less than the width of the screw head.




We insert the block adjusted to its cross-section into the groove of the sole and attach it to several screws using a screwdriver and a Phillips bit.




There are bolts at the end of the heater contact group. We drill slot holes for them on both sides of the block, and unfold the contacts with pliers to connect them.




We press the contact plates with several self-tapping screws - press washers.




Not far from the end of the sole, we drill a hole for the clamping bolt for the sleeves. Now you can attach several paired welding attachments. We place them on the clamping bolt and tighten them with a hex wrench.




All that remains is to connect the power cable to the contact group, and wrap the contact area on the handle with electrical tape.






The soldering iron is ready for use. Such a device can be used for soldering polypropylene pipes and fittings, making plumbing or heating wiring.




Conclusion
Despite the simplicity of the design, it cannot be considered completely modified. It does not have a heating thermostat with automatic protection. The ergonomics of the tool also leaves much to be desired, because such a device must stand firmly on its edge during operation. However this homemade apparatus serves as proof that if desired, even specialized tool can be assembled from scrap parts.

Often, when operating household plumbing systems made of polypropylene, there is a need to repair or expand them, which is impossible without special soldering equipment. As a tool suitable for these purposes, purchased devices of a special design are usually used, the high cost of which forces users to think about making them themselves.

This approach is good not only because it allows you to save significant money and not waste time learning how to work with unfamiliar equipment. Thanks to self-production it is possible to study all the intricacies of handling such devices, which ultimately affects the quality of soldering of polypropylene and other plastic pipes.

In the case when a decision is made to make a soldering iron for pipes with your own hands, this can be done by using the old spare parts remaining on the farm. One of the most common options for making it from improvised means involves using an old electric iron for these purposes.

To implement this project you will need the following components and spare parts:

• an old iron designed for a power of at least 800 watts;
• duralumin plate of suitable size;
• steel slats from an old children's construction set;
• wires, a toggle switch, an unnecessary handle from a disassembled drill or grinder to make it convenient to hold the soldering iron.

A soldering iron for iron pipes works on the same principle as a factory-made specialized product. The spiral (heating element) heats up, transfers heat to the sole and the nozzle inserted into it. This allows you to melt polypropylene pipes and solder them. The temperature on a homemade soldering iron is set to the maximum (should be 260-265 ℃). Having prepared all these parts and materials, you can begin assembly.

First, the casing is removed from the iron, which allows access to its insides. Then the working part of the sole is cut off using a grinder, and in its place, a duralumin plate cut to the shape of the base is attached with an existing bolt. Next, you need to assemble a box from the spare parts of the designer and securely fasten it to the sole.

A toggle switch and a grinder handle are fixed to the elements of the box, after which one end of the power cable is connected to the switch. The second conductor, together with the outlet from the toggle switch, is connected to the heating coil through asbestos tubes.

Nozzles for fixing on polypropylene pipes will have to be purchased separately. If desired, you can connect a socket with a light bulb in parallel to the power circuit, the current through which must be limited by means of a quenching resistor. In order to do this simple design It will take a minimum of time to do it yourself.

With heating regulator

To control the heating temperature homemade soldering iron for polypropylene pipes, install a thermocouple. To assemble a device equipped with a heating regulator for the working sole, you will need additional details and spare parts, namely:

• thermostat, thermocouple and two tips;
• dial indicator with a special scale (with “zero” and two sectors);
• insulated conductors with a length of at least one meter each;
• asbestos wool.

Even before starting work, you should contact a turner and ask him to make two tips of a special shape (for the fitting and for the heater outlet). The dimensions of these tips are selected based on the diameter of the tube prepared for assembly.

The procedure for assembling a soldering iron for polypropylene with a thermostat with your own hands looks like this:

1. First, the casing is removed from the iron, after which the temperature regulator is removed from its sole, as well as all unnecessary details and wiring. After such disassembly, you should be left with a clean ironing plate.
2. Then, using a drill, holes with a diameter of about 6 millimeters are drilled in the tips, after which they are bolted to the body, cleared of foreign parts (from the “nose” side). On the opposite side of the base, holes are drilled in it with a diameter suitable for mounting the thermocouple housing.
3. Wires about one meter long are soldered to the thermocouple. Following this, the same conductors are used to connect the heating coil. All these wires are led out through a hole in the handle of the iron. It itself is attached directly to the casing.
4. At the final stage of work, the space between the casing and the slab is filled with asbestos material (wool), which acts as a heat insulator. Upon completion of this operation, the casing is returned to its place, resulting in a housing with two pairs of conductors brought out.

These wires are connected to the power plug and the thermostat according to a circuit that allows you to set a given value for the melting temperature of polypropylene (255-265°).

Thermostat circuit and printed circuit board

Industrial designs with paired nozzles

For the manufacture of thermal nozzles for industrial soldering irons, special materials are used that conduct heat well (copper, aluminum alloys and the like).

On the outside, they are coated with a special layer that prevents polypropylene from burning (Teflon is most often used for these purposes).

Known samples of nozzles for soldering propylene pipes differ both in their shape and in the method of attachment to the heater, which can be various designs. In this case, preference is usually given to products that allow the installation of paired nozzles (or several pairs of them at once).

The capabilities of such a device are significantly expanded, since it becomes universal in its technical parameters.

The working dimensions of soldering iron nozzles (their diameters) must correspond to the same indicator for polypropylene pipes and have values ​​from 16 to 110 millimeters.

Special nozzles with sizes from 20 to 32 millimeters must be included in the kit of any soldering iron that belongs to the category of semi-professional devices. Specialized models of soldering fixtures can be equipped with a large number paired nozzles, the size range of which has been expanded to 63 millimeters.

Choosing a soldering iron for polypropylene pipes

Polypropylene pipes today have almost completely replaced the previously used metal pipes. However, if the latter were connected exclusively through threaded connections, then to connect plastic parts Today they use special equipment and tools. One of them is a soldering iron for polypropylene pipes (it is sometimes called an iron).

This device is especially popular among craftsmen who independently install heating systems and plumbing, without the help of specialized companies. What characterizes this popular instrument today?

Types of soldering irons

The design of the machine for soldering polypropylene pipes is quite simple. It consists of a heating element that transfers heat metal plate having holes for nozzles.

The main task of the soldering iron is to maintain a constant level desired temperature. The main difference between these devices is the method of attaching the nozzle to the heating surface.

In Russia, sword-shaped soldering irons and corresponding nozzle designs are more common. This is due to the relatively low price and large assortment. However, among professional tools increasingly you can find cylindrical heating devices.

Soldering iron for soldering sword-shaped polypropylene pipes

Another main criterion when choosing a soldering iron is constant temperature. The reliability of the pipe connection depends on this characteristic. On sale you can usually see a whole set for soldering pipes. It includes the soldering iron itself, several attachments, and sometimes the kit is supplemented with scissors for cutting pipes.

Soldering iron power for polypropylene pipes

The heating speed depends on its value. All tools of this kind are designed to use a 220 volt network. For installing pipes at home, a soldering iron with a power of 700 to 1200 watts is suitable.

Minimum power sufficient for soldering pipes with a diameter of 16-63 mm. When connecting pipes with a diameter of 75 mm, you will need a soldering iron with an output of at least 850 W. And 1.2 kW must be used when soldering products with a diameter of up to 125 mm. In any case, if you are connecting yourself, you will need a soldering iron for soldering polypropylene pipes with a power of no more than 1.5 kW.

Any soldering machine is equipped with a thermostat located directly on the body.

Optimal temperature for soldering +260С. At a lower temperature, the pipe fits into the nozzle for too long and too tightly, which does not ensure a good connection between the fitting and the pipe.

The thermostat automatically turns off the tool when the set temperature is reached (this is indicated by a light bulb or LED).

Iron attachments

Most efficient use soldering iron is possible only if several attachments are installed on it at the same time. And indeed, change them when the soldering iron is hot #8212; a very dubious pleasure. Produced nozzles for soldering iron polypropylene pipes allow you to connect products different diameters.

Welding machine complete with nozzles

In the manufacture of nozzles, to increase their strength and durability, they use various coatings. Most often this is Teflon (or metallized Teflon, which is a more durable option).

To extend their service life, before starting soldering, be sure to remove any melt residue left after previous works.

Cost of the device and fittings

All manufacturers recommend using a soldering iron for plastic pipes with a diameter of 16-63 mm, with a power of 680 W. If it is necessary to connect pipes with a diameter of up to 75 mm, then the power should be greater - up to 850 W. When working with large diameters, up to approximately 125 mm, experts recommend using soldering irons with a power of 1200 W.

Soldering iron attachments

Soldering iron attachments for pipes. The size of the nozzle depends on the diameter of the plastic pipe

As a rule, when connecting polypropylene pipes in large volumes, already ready-made blocks. But this is not always beneficial for the home; there may be a need to install just a few separate pipes, so when choosing a soldering iron specifically for home use It is necessary to pay attention to the presence of all attachments.

You also need to pay attention to the material of manufacture; it can be metallized Teflon or regular Teflon. At the same time, the first one is higher, it requires a careful, careful attitude. Before use, they must be wiped with isopropyl alcohol.

Temperature level adjustment

When choosing a soldering iron for installing plastic polypropylene pipes, you need to pay close attention to the ability to adjust the temperature level. Adjustment accuracy from one to five degrees can be achieved using only a professional soldering iron, but it will be needed when the volume of work is very large. At home, you can often get by with cheaper models, but you should still choose them carefully.

The temperature when connecting parts should not be equal to or greater than 270 degrees, since at this value the thermal degradation of polypropylene pipes begins. Optimal value is to support a temperature value of 260 degrees, so when choosing, make sure that the rhythm of the difference is not too large.

When choosing, remember that attention should be paid to the temperature not on the soldering iron regulator, but on the nozzle. Experts recommend purchasing an additional special thermometer, which will allow you to accurately determine the temperature value so that the soldering is of high quality and the pipe itself is not damaged. Besides , modern models devices have sound alarm: When a certain value is reached, an alarm will sound. Such devices allow you to monitor the condition in three modes (for heating, for connecting polypropylene pipes, for fixing).

When buying a soldering iron for plastic pipes, you need to pay attention to every little detail, since the quality of installation and the pipe itself often depends on them. A soldering iron for plastic pipes must not only be reliable, but also have the ability to control temperature, be easy to use, and have all the necessary attachments.

Soldering iron for plastic pipes

Quite often, when carrying out repairs or during the construction of buildings, it is necessary to carry out pipelines. Modern technologies allow the use of plastic pipes in almost all communications. made from durable polymers. Water supply plastic pipes, despite their high strength, have a low price, are not afraid of corrosion and do not become overgrown inside with deposits of salts and lime.

Hot and cold water supply in the apartment, laying water supply on summer cottage and installation of pipelines when installing heating systems - plastic pipes are used everywhere. Special soldering irons are used to work with polymer pipes. which perform heating of pipes and other pipeline elements (angles, tees, crosses). The connected heated parts of the pipeline are soldered into a single whole and do not allow water to pass through, which is what is required from the plumbing or heating system.

A soldering iron for plastic pipes is sold in almost any household or hardware store. Their cost is relatively low, especially when you compare their price and the cost of work on laying water lines in an apartment or house, which the craftsmen will require from you. Of course, if you need to add a tee to install a washing machine, then there is no point in purchasing a soldering iron - it’s easier to call a mechanic from the housing office. But if the renovation of an apartment or house is major, then a soldering iron for plastic pipes will pay for itself quite quickly.

The principle of operation of a soldering iron for plastic pipes is simple - inside it there is a heating element, which heats up from a voltage of 220 V, and from it the nozzles for pipes and other elements heat up. The nozzles, which are sold as a set along with the soldering iron, have a diameter of #189; up to 2 inches and allow you to perform necessary work With various pipes. The tips are screwed onto the soldering iron with different sides, which allows you to simultaneously heat the pipe from the outside, and connecting element from the inside.

However, it is best to work with a soldering iron with a partner, when one holds the soldering iron, and the second heats up the necessary sections of the pipeline. But if there is no partner, then you can do it yourself, but this will require skill and work gloves - so as not to get burned. Special scissors are included with the soldering iron. which allow high-quality cutting of plastic pipes various sizes. Of course, you can cut the pipe with a hacksaw, but scissors will do it much faster.

When buying a soldering iron for plastic pipes, you need to pay attention to the presence of a rheostat on the soldering iron, which serves as a temperature regulator. At the maximum temperature level, a soldering iron when turned on will not only generate extra kilowatts for you, but can also unnecessarily melt plastic pipes. This usually happens in hard to reach places, where it is not possible to work comfortably and excessive use of a soldering iron greatly melts the pipe or the joining element (tee, angle, cross, joining barrels). During operation, it is better to regulate the set temperature than to redo a certain section of the pipeline several times.

Of course, when carrying out repair work Other power tools will also be required. and the tools. But the soldering iron is for polymer pipes When carrying out plumbing work or installing a heating system, it will come in handy.

Plastic plumbing has come into our everyday life for a long time. An invariable attribute of the repair of the Soviet housing stock, along with metal-plastic windows, the water supply system was made of polypropylene pipes.

Advantages polypropylene water pipe before steel pipes are obvious:

• Cheapness and wide choose materials;
• Simplicity of work on marking and assembling the most intricate and complex options pipe routing;
• Environmental friendliness, resistance of the material to corrosion and salt deposits on the walls of polypropylene communications.

Those who have encountered the tedious and time-consuming procedure of installing a water supply system from metal pipes can appreciate simple technique connecting plastic using a special soldering iron for polypropylene pipes.

If the time has come to renovate the apartment, the problem of replacing the water supply with plastic communications, depending on the availability of desire, money and free time, can be solved:

• Hiring a craftsman and a friend who has experience working with a device for soldering propylene pipes, who can help assemble pieces of plastic pipes marked and cut into a single whole using a soldering iron;
• Transferring the issue of turnkey repairs to a team of repairmen without any desire to understand the intricacies of assembling and soldering plastic components;
• Doing all the work yourself.

The simplicity of assembling the soldering of plastic is so captivating that it is difficult to resist the temptation and solve the problem of plumbing in no other way than to choose and buy a soldering iron for polypropylene pipes.

The amount of money spent on purchasing the tool will be less than the cost of the specialist’s services, but provided that you really understand how to choose a soldering iron for polypropylene pipes. Essentially, the soldering iron for propylene parts and connecting fittings is a heating element with thermomechanical or electrical system heating control and indication. Two nozzles are mounted on the heater, allowing you to simultaneously heat the outer surface of the pipe and inner surface fitting. Heating lasts on average about 5 s, the parts are connected with slight manual pressure to set and form a strong connection within 2-3 s. If parts are overheated or connected lopsidedly, some of the molten plastic may get inside the pipe, and as a result, the flow area decreases.

Important ! By performing most of the soldering and assembly work yourself, you are able to personally control the quality of soldering of polypropylene pipe joints.

For innovators and DIY enthusiasts, you can assemble a soldering iron for polypropylene pipes with your own hands. The strength and durability of the soldering depends on the perfection of the soldering iron and how high-quality the polypropylene pipes are.

What is good about a DIY soldering iron?

The operating principle of the soldering iron is simple and uses the principle of adhesion of the soldered surfaces of polypropylene parts heated to the softening temperature. There is not always a need to re-wire or re-solder half of the water supply wiring in the house. Sometimes you need to work with a soldering iron to make two or three connections. In this case, a homemade, do-it-yourself mini-soldering iron for polypropylene pipes from a handy heater can help out.

For a person with experience working with electrical wiring and plumbing skills, making a small amateur version of a soldering iron for polypropylene pipes is a matter of two hours.

As a rule, water pipes are laid in channels and hidden from prying eyes with screens and decor, so you don’t have to worry about beauty and aesthetic appearance. Another thing is important - incorrect temperature adjustment and overheating of the pipe or fitting material, even under slight force, will lead to defects. In soldering, the first and main issue remains the quality of the connection of parts.

If, when working with a homemade soldering iron, you may fall slightly short of world standards appearance- no problem, for amateur cases this is allowed.

To assemble a homemade propylene pipe soldering iron you will need:

• The heating element is the soleplate of a regular electric iron, preferably in the form of a closed aluminum block with a thermostat and an electric cord with a plug;
• soldering iron attachments for polypropylene pipes and fittings required size for your pipes;
• nickel-plated M8 bolt-nut for attaching nozzles to the heater;
• digital multimeter with external thermocouple thermometer;
• a clamp or other fastening that allows you to securely fix the soldering iron on a utility surface.

In addition to temperature, the speed or power of heating the surface of the parts being joined is important. If heated polypropylene fitting or a pipe for a long enough time - the parts will lose their shape and geometric dimensions under the influence of temperature.

Therefore, to quickly melt a surface with a diameter of 15-30 mm, a power of 700 - 900 W is required, which approximately corresponds to the maximum power of the iron heater.

We assemble a homemade product for propylene couplings:

1. At a distance of 30-40 m from the nose of the aluminum sole we drill through hole with a diameter of 8 mm and using a screw and nut we connect the nozzles for the pipe and fitting to the base of the heater;
2. We install the iron handle on the heater sole so that it does not limit access to the attached attachments;
3. We connect the wiring to the contacts of the iron heater;
4. We turn it on and use a multimeter, a digital thermometer and a regulator on the iron to set the temperature to 265 o C.

We use a clamp to fix a homemade soldering iron of polypropylene pipes, which will allow you to solder parts yourself, without an assistant; the handle can also be made to suit you for the greatest convenience and minimal risk of getting burned.

Which soldering iron is better for polypropylene pipes

It has always been believed that the best tool is professional option, designed for long-term use and with high parameters for soldering propylene pipes. Professional soldering iron for polyethylene pipes assumes:

• The use of materials for nozzles that are resistant to prolonged heating, with high thermal conductivity, and that do not stick to the heated surface of the polypropylene part; as a rule, brass or copper nozzles coated with Teflon or carbon are used;
• Easy and convenient change of nozzles on the heater flange; the kit includes a set for the main pipe sizes - from 16 to 160 mm;
• The metallized surface of the nozzles gives high speed heating polypropylene parts;
• The presence of a heater power supply stabilizer and automatic temperature regulation allows you to keep the soldering iron hot for as long as desired without the risk of failure of the heating element.

Mandatory attributes of professional models of soldering irons are an easily removable stand and a case for storing and carrying the device with accessories.

For your information ! U original models soldering irons, unlike counterfeits, markings and information about the model are applied typographically to the body or to a metal substrate plate tightly sealed into the plastic. On fakes, the marking is pasted in the form of a metallized label and is easily separated from the soldering iron body.

For example, the widely known version of the soldering iron for polypropylene pipes is dytron or ditron - as you like. He is highly praised for his reliability and ease of use, unpretentiousness and robust construction. When soldering propylene parts, time passes by seconds; you have to quickly set up, drop or even throw the pin on the stand, and this practically does not affect its performance. There are three models in the DYTRON line:

• Power 850 W, the most popular in apartment renovation, used for polypropylene pipes with a diameter of up to 36 mm;
• Power 1200 W - for polypropylene pipes with a diameter of up to 160 mm;
• With a rod-shaped heater with a power of 650 W.

The soldering iron comes with a key for changing tips, which can be from 3 to 12 in a set, scissors for cutting polypropylene pipes, a building level, gloves and a stand. With all the advantages, it is worth noting one negative point- clearly overpriced soldering iron.

Important ! Such devices are designed for many hours of operation, but in any case, they require careful care. non-stick coating on the nozzles. Teflon is very sensitive to scratches and chips, so you should not use hard or metal objects other than rags for cleaning.

But even specialists involved in soldering water pipes do not always strive to buy a soldering iron for polypropylene pipes in an expensive professional version. Many of budget models, assembled from Chinese or Turkish components, work great no worse than branded models.

Let’s take, for example, a typical repairman’s workhorse—the Soyuz soldering iron for polypropylene pipes:

• High heater power - up to 2 kW;
• The kit includes six standard nozzles with a diameter from 20 to 63 mm;
• In addition, the soldering iron is equipped with a hexagon wrench for changing the working tool, a stand for the device and a case.

The length of the power cord is only 130 cm, which is clearly not enough for work. But this size is typical for budget models, while professional soldering irons have a full 2.5-3.5 m. The Soyuz is equipped with a two-mode push-button heating control system and two color indicators - green and red, the latter lights up when the heating is turned on automatically.

The soldering iron is equipped with everything necessary for successful soldering of polypropylene pipes, so it’s difficult to say whether it’s worth overpaying for additional accessories, as in the case expensive models soldering irons

Do you want to repair or replace communications made of polymer pipes? Agree that it’s not a bad idea to save on calling a technician by assembling a new pipeline yourself. But you don't know how to connect individual elements systems among themselves and what is needed for this.

The article we presented describes in detail the technology of welding polypropylene pipes - any novice plumber can connect them with his own hands. We will tell you what you need to consider, how to use a soldering iron to join plastic elements. We will tell you in what cases other methods are used.

To help the novice master, we have selected detailed videos demonstrating step by step process performing polypropylene welding, and photo illustrations.

One of the undeniable advantages of polymer pipes is their ease of assembly.

Installation of elements can be done almost anywhere: laying open method on the walls or placed hidden under the floor.

If the welding of water pipes made of polypropylene is carried out correctly, then the assembled system will serve without repair for decades

Polymer pipes are produced with diameters from 20 to 110 mm. For household purposes, products of sizes 20/25/32/40 mm are most often used. The area of ​​application determines the nominal pressure of the material.

In the marking it is indicated by the letters "PN":

• PN 10– chosen for arranging cold water supply.
• PN 16- used for cold water, but with higher pressure, as well as when installing a “warm floor” system.
• PN 20– products, the only limitation of which is temperature regime liquids transported through them. It should not exceed 75 °C.
• PN 25– universal products used for arranging both “cold” and “hot” systems, the temperature of which reaches 90 °C.

On sale you can find polymer products equipped with additional reinforcement.

Reinforced products are used for laying over long sections in conditions where it is necessary to reduce linear expansion that occurs during temperature fluctuations

The main feature of polymer pipes is their inability to bend.

Therefore, all changes in the trajectory of the laid highway are carried out only from straight sections connected to each other by auxiliary fittings:

• crosses– for the possibility of branching the main flow;
• tees– flow multipliers;
• couplings– for connecting pipes in a straight section;
• bends– for changes in pipeline direction.

Fittings can be equipped with fused metal threads, which make it possible to connect a polymer pipeline with metal elements.

To ensure that the seams are as strong and airtight as possible, it is important to ensure that the diameters of the joined elements match exactly

When choosing auxiliary elements, you should take two parameters as a basis: internal section products and the thickness of their walls. These parameters must match technical specifications polypropylene pipes used.

Methods for connecting polymer pipes

When joining pipes made of polymer materials, depending on the installation conditions, one of two methods is used:

1. Soldering– involves heating and joining the molten ends of the elements.
2. No soldering– involves connecting pipes through compression fittings or by implementing so-called “cold” welding.

The second installation method is convenient in the sense that there is no need to use special equipment to implement it. All work can be done using simple tool– crimp key.
