In an arc welding machine that uses shielding gas and controls the release and stop of the shielding gas by opening and closing a solenoid valve, commands from the welding control circuit
Multiple solenoid valves that are selectively opened at each control stage of welding machine output current such as start current, main welding current, and crater filler current are attached to gas passages with different shielding gas flow rates, and each gas passage is connected in parallel. An arc welding machine characterized in that the shielding gas flow rate can be switched in accordance with the output current value of each control stage.
