TIG Basic electrode since 70% of the heat is concentrated at the work piece. Welding Guide TIG Welding is a fusion procedure that uses an elec- tric ARC created between an infusible tungsten elec- trode and base material to be welded. For TIG weld- ing an inert gas must be used (Argon) which protects the welding bead. If filling material is used, it is made up of rods suitable to the material to be welded (steel, stainless steel, copper etc). - Page 25 WT160MP Welding Machine (Fig 16-3) ARC Welder Point Grinding Wheel Radial Ground Wrong Tungsten Preparation - Wandering ARC Diameter of the flat determines amperage capacity.
