Abstract
Two-operator machine for TIG welding of copper in helium was developed. The machine consists of the main module (power source) and two remote modules powered by 3 36 V voltage and having a self-sufficient system of antifreeze cooling. The machine ensures an independent adjustment of welding current of each of the two stations, welding current stabilization, reliable and fast arc excitation and stable arcing in helium in copper welding.
Keywords: TIG welding, copper, helium, current pulses, power transistor, choke, inductance, welding current adjustment, two-operator power source
