Inverter Power Source

The article presents results of researches on manual arc welding efficiency development. It is proved that the arc welding inverter power source, compared with the diode rectifier, increases coefficient of transition of alloying elements into the weld joint; it also reduces the rate of alloying elements transition into slag and gaseous components and in addition reduces the harmful effects of welding on human organisms.
