How to choose an inverter welding machine

Modern inverter equipment is much more efficient than its transformer predecessors. Using these devices, welding works are high quality and faster. Many of the models of the devices create some difficulties in the selection of the welding inverter. The solution to the problem is to simply follow a clear algorithm of action.

First, we are determined with the voltage type - 220V or 380V. Then analyze the stability of the power grid on the site of the alleged work. As a rule, in the city the indicators are more or less normal, and in the country or in the village below the normative. In the second case, the inverter is selected with the lower threshold of the operating voltage of at least 160-170V.

Select the required welding current. It depends on the diameter of the electrodes used, and therefore the thickness of the weldable products. This is calculated: 1 mm of the electrode is melted under the action of the current of the current 35a. For metal 2-3 mm thick, the electrode of diameters is 2.5 mm, respectively: 4-5 mm - 4 mm, and for 8-10 mm - 5 mm. We add another 20% of the power supply, which can be useful when expanding the spectrum of work and possible drops on the network.

We look at the power consumption of the power, which is always much higher than any previously connected home appliance. Not in every socket can be turned on the welding inverter. Small power devices are easily connected to autonomous generators.

We draw attention to the duration of inclusion (PV). The fact that this figure is lower, the smaller there will be the time of operation of the inverter and the period of its cooling. It is customary for 100% a ten-minute period of time.

We estimate the additional functions of the unit, the most significant are as follows:

Overload protection - saves with a short circuit and voltage jumps;
Anti Stick - prevents the electrode sticking;
Overheating protection - increases the service life of the device;
Hot Start - facilitates arc ignition;
Arcforce - keeps the stable burning of the arc.

Such options will be useful for those who are just starting to get acquainted with welding work.

Having studied our advice, boldly buy the necessary equipment. Becoming the widdle inverter, do not forget about the correct care of the technological device. Clean from dust, do not contain it in the cheese and cold place.
