Abstract

A method and apparatus are provided for removing spatter from a torch of a gas shielded arc welding apparatus. After a series of welding operations are completed, pressurized air mixed with a small amount of oil is injected through a passage defined between a member supplying a welding electrode and a gas nozzle. This oil emitted adheres to the surface of the electrode supply member and the gas nozzle, thereby generating an oil film thereon. The pressurized air removes any spatter on the apparatus and the oil film prevents any further spatter from adhering to the surface.
