EVOLUTON GH Heads are 10W faced electrodes designed for projection welding. The part has a stainless-steel bushing for wear resistance and improved redressing. The Hex body allows for easy installation and removal of the part.

A refractory metal face made from RWMA Class 11 (75% tungsten, 25% copper) (ASTM 702 C1D) is brazed onto the base material. This face is typically used for welding at higher pressure and heat common with projection welding.
