Abstract
A welding system includes a welding torch that welds a workpiece by using a wire, a suction device that sucks shielding gas, and a sucked shielding gas supply path for allowing the sucked shielding gas to flow, wherein the welding torch includes a contact chip that guides the wire, a shielding gas supply nozzle that supplies the shielding gas to a weld zone, and a suction nozzle that surrounds a periphery of the wire protruding from the contact chip, and is opened toward a tip of the wire to suck the shielding gas.
