TIG Welding Outfits The TIG welding (Gas Tungsten Arc) process uses a virtually non-consumable tungsten alloy electrode to form the arc between the power source and the weldment. MIG Welding Outfits In Gas Metal Arc Welding(GMAW) an electric arc is established between the workplace and a consumable bare wire electrode. Plasma Cutting Outfits Plasma Cutting is a process where an open arc can be constricted by passing through a small nozzle from the electrode to the workpiece. Submerged Arc Equipment Submerged Arc Welding is a MIG process that has a high deposit rate and is the fastest method of welding 1/8 in. (3.2 mm) and thicker carbon steel plate. Carbon Arc Equipment A carbon electrode can be used as a non-consumable in the basic welding circuit. Portable Arc Welders Portable Arc Welding is the Stick welding (shielded Metal Arc) process using a Portable Gas powered or Diesel powered welding generator.
