How to make a homemade soldering iron for polypropylene pipes? A good master always has high-quality tools at hand. Even at home there is always a tool, and if there is no suitable one, you can assemble it yourself. If you decided to change the sewer, water, heating pipes, you will definitely need a soldering iron for polypropylene pipes.
For welding polypropylene pipes, a special soldering iron is used, which acts on the iron principle.
Now it is very rare to find iron or cast iron pipes, plastic material has become very popular.
Which soldering iron is better?
There is a very large selection of this product. Sales assistants will offer you many tools, but they won’t answer which one is better. Therefore, first of all, it is necessary to pay attention to the country of origin. Now the Czech Republic ranks first in the ranking of the most popular soldering tools, followed by Turkey, in third place is Russia, and in fourth place is China.
Such an apparatus is used to heat the ends of polypropylene pipes and further connect them with each other. The device is made so that you can work with different diameters of pipes. To get it right, you need to know the temperature of the equipment. The configuration of the soldering iron consists of a sole, two heating heating elements, and nozzles of various diameters that are mounted in special holes.
Soldering iron allows you to easily connect the ends of polypropylene pipes of any size.
To understand the principle of operation of the soldering iron, it can be compared with the work of the iron. But the iron is equipped with one heating heating element, and a polypropylene soldering iron - two. He also has a thermostat and an additional built-in tool - a tape measure. Also included is a spirit marker, level, plastic pipe cutter.
In order to start working properly, you must first study the technology of soldering. The soldering iron should be installed on special legs (they are included), and only then be plugged into the network.
Choose an element according to the size of the connector, which is designed for the soldering itself. You heat up to the maximum temperature, connect the ends very quickly and evenly and press down to each other.
In order for everything to work out well the first time, the soldering iron needs to be warmed up for the maximum temperature - about 20 minutes, then you need to wait 5 minutes for the nozzles to warm up.
The process of soldering will take about a minute, but it is better to read the instructions for the device. If there is a pause in the process of soldering, do not try to reheat, as the pipes are plastic and the material itself is stretched, which means that the seam may be damaged.Back to table of contents
Homemade soldering iron for soldering polypropylene pipes
The main parts of the soldering iron.
If the device you can not afford or there is no extra money to purchase a soldering iron for polypropylene pipes, you need to do it yourself. This technique can be made on the basis of an old iron.
You will need:
- 800 watt iron;
- a heater (not with a helix, but with a heating element, preferably in an aluminum case);
- chromel-copel thermocouple;
- two tips;
- two wires about 1 m long each;
- old tape recorder;
- asbestos wool;
Stages of work
It is most convenient to make a homemade soldering iron for polypropylene pipes from an old iron.
From a plate of the iron remove the temperature regulator. Remove all unnecessary protrusions and wiring, one bare plate should remain.
Go to the turner and order two tips, one for the pipe, and the other for the fasonina (under the nozzle and nut). Take the dimensions yourself, for this measure the diameter of your pipe.
When the turner does everything, use a drill to drill a hole with a diameter of about 6 mm, take the bolts and fasten the tips. Drill a hole on the opposite side of the nose of the iron so that it is free to install the thermocouple.
All parts are connected and assembled in a casing. Take a wire with a length of about 1 m and attached to a thermocouple.
Then another wire of the same length is taken and connected to the heating element. Out through the top of the handle. The handle itself is attached to the outside of the casing.
At the next stage, it is necessary that a space is formed between the casing and the tile, it must be filled with a thermal insulator, you can take a simple asbestos cotton.
Scheme homemade iron from the iron.
You should have so that two tips will protrude beyond the casing, they need to be insulated.
Now place the thermostat itself, it must be placed separately and preferably in a plastic case. Plexiglas and dichloroethane can be used.
An old tape recorder can be useful for indication, there is an indicator, and there are arrows and, most importantly, a zero mark. By all the rules, this label will be 270 °.
If the arrow will show in the red sector, then the temperature is above the norm, and if in the yellow sector - below.
Another important element is a resistor, it is derived outside the thermostat housing.
It will show whether the heating element is working.
The process itself is as follows. As soon as you turn on the soldering iron in the outlet, you need to set the temperature to 270 ° with a pen.
The LED will light up and give a signal that the soldering iron begins to heat to the desired temperature, and when it goes out, you can start work.
Deciding what is best - to collect their own hands or buy, only you. A new soldering iron in the construction market will cost 15-18 thousand rubles. If you want to assemble yourself, it will cost only about 2 thousand rubles. as the old iron is always in the garage of any owner.
