Plasma Arc Welding (PAW) is a welding process in which an electronic arc ionizes a gas, generally argon (in some cases mixed gases are used; argon/helium argon/nitrogen) creating a super heated highly focused plasma arc column that generates the heat for welding. PAW is similar to TIG/GTAW welding except that the arc is focused through a constricting tip orifice which provides a much stiffer arc, with deeper penetration and a narrower heat affected zone.

Plasma Arc Welding is clean and quiet, producing beautiful, cosmetic welds suited for high-precision/automated welding applications of exotic or thin materials down to foil thickness. The PAW process is particularly well suited for industries such as bio-med, pharmaceutical, food service, brewery, power generation, aircraft, aerospace, automotive and special interest auto, marine, and sporting equipment. The process can be manual, semi-automatic or robotic.
