FIELD: technological processes.
SUBSTANCE: invention relates to welding torch (100) for arc welding in protective gas. Burner comprises contact tip 25 for supply of welding wire 13, suction nozzle (23) for gas suction from space that surrounds periphery of welding wire and is formed between welding wire and suction nozzle 23, and supplying protective gas nozzle 21 for supply of shielding gas to welding area from space, which is available on outer periphery of suction nozzle 23 and is formed between suction nozzle 23 and protective gas supply nozzle 21. Distance Lts [mm] from working end of contact tip 25 to working end of protective gas supply nozzle 21 and distance Ltk [mm] from working end of contact tip 25 to working end of suction nozzle 23 along longitudinal direction of welding wire satisfy following ratios: 7≤Ltk≤17 and 0≤Lts≤18.
EFFECT: welding torch for arc welding is proposed.
