Automatic welding machine
Welding is used in all industries, except for the construction of large buildings. It is worth remembering that this station producing electric current for electric arc cutting and welding, can include additional nodes. To such nodules distribute the device for powering devices, a device for underestimating the electric load of the free wheeling, the method of current control, the device for heating the concrete, the apparatus for heating frozen ground, the block for heating ice in reservoirs and lakes, and also adapting VPR( air-plasma cutting).
Very often, users confuse generator sets that have a drive from a power selection box or from a power take-off shaft with a welding machine that has a drive from a stand-alone internal combustion engine. It is necessary to more accurately call generator sets a welding prefix, because there is no autonomy.
Welding machines are divided into different types. To solder different metals, different types of apparatus are needed. For example, for stainless steels, an automatic machine with a well-balanced current or a built-in oscillator is used, which can be an equalizer or an electronic amplifier. Therefore, this kind of welding should be shown on the rating plate or in the passport and the type of the electrical conductor is also indicated.
Welding machine with its own hands
The fact that the generator that generates current is indispensable in our life, we have already decided, but that's not all have the opportunity to purchase it. Therefore, now we will consider how to assemble an inverter welding machine independently. Why inverter? Because inverter machines have the greatest demand, but also a high cost.
For inverter it is necessary to find the electrical circuit, which is based on the value of the desired current for welding, the prevalence of its components and the reality of reproduction at home.
In the standard max.the level is set in the period from 40 to 130 A. This allows you to boil an electrode with a diameter of up to 3 mm. It is possible, and what practice says, you need to use the details of unnecessary televisions for the manufacture of this welding machine.
Further we consider whether it is necessary to install an output transformer and a fan. The body, most often, is made of sheet steel. Further on, we fix the toggle switch and the turn-on indicator on the upper part, most often LED, resistance is variable. On the case we fix the clamps for the cables.
But do not confuse the machine with a semi-automatic machine for welding, as there is a great difference, this is welding in an inert gas, which excludes oxidation in the welding zone. As a result, there is no dirt on the welding seam, the seam is smooth and aesthetic, and does not require further processing.

How to choose an extension for the
welding inverter First, let's consider what an inverter is.
So, the inverter is an unchanging current device. The incoming voltage at the input is equalized, then reincarnated into an alternating voltage supplied to the transformer.
The inverters are different. They differ in weight, which is usually from 3 kg, dimensions and a small dependence on the voltage entering the inverter. Just because of the size, the dignity of the inverter is mobility.
Inverters are used when welding work is needed in the field or in high-altitude work. For convenience, an extension cable for the inverter is often needed.
How to choose an extension for the inverter?
So, an extension cord is a cord that transmits electric current. To be more precise, this is part of the safety technique, because for welding works the device must be at a distance of 2 m. Often, such an apparatus is required that will reach 20-30 m. And remembering Ohm's law, if the resistance increases, the load decreases. It is necessary to choose such an extension element, which min has an effect on the voltage in the electric network. But, simply put, look at the wiring gauge in the place where the extension cable will be used, and choose it no smaller than the wiring.
Welders advise not to reel the cable on the coils, as the phenomenon of the appearance of an electric current in a closed loop is created, as a result of a change in the magnetic current that passes through it. As a result, the cable overheats and often the insulation melts.
It is necessary to leave between parts of the folding distance cable. Often overheating of the wire reaches up to 70 ° C during operation. If the overheating is greater, then it is necessary to postpone the work for a while. If the device itself is turned off when the wire temperature rises, there may be a reason in the low voltage of the current in the network.
Therefore, when choosing an extension cable, it is worth considering all of its features and capabilities. Remember, your work depends on your safety and the safety of others.
