Abstract
A welding torch includes a gas lens of a lattice structure that straightens a shielding gas. The welding torch includes a non-consumable electrode, an electrode holder into which the non-consumable electrode is inserted, and a torch body including a sleeve that holds the electrode holder, a flow path forming portion that forms a shielding gas flow path around the sleeve, and a nozzle that forms a shielding gas guiding space around a distal end of the non-consumable electrode, the distal end extending from the electrode holder, in which the gas lens is provided so as to separate the shielding gas flow path from the shielding gas guiding space.
