The AC/DC TIG 200P welder is a powerful aluminum TIG welding machine that offers welding with TIG AC Square/Triangular/Pulse Square/Pulse Triangular/DC Pulse/DC/Stick methods. It can be used for welding various metals, including aluminum, steel, stainless steel, carbon steel, and copper. The technology improves arc striking speed, welding efficiency, and results, while the pulse, square, and triangular waveform functions prevent material burning, minimize distortion, and improve bead appearance. Additionally, you can choose between 2T/4T/Spot welding TIG torch control and foot pedal remote control methods for a more versatile experience (foot pedal not included).
