High-quality, 5-200Amp TIG welder for all ferrous materials including mild and stainless steel and copper, providing stabilised arc and constant current in any welding position. SPOT provides fast and precise spot welding before joining thin sheets. Pulsed DC TIG controls the temperature of the weld pool, reducing deformation for sheets from 0.3mm to be assembled. Can also be used for 10-160Amp MMA (ARC) welding.
