The Square Wave TIG 200 is a portable TIG and stick welding machine that lets hobbyists, makers, small fabricators and craftsmen explore their creativity, no matter your skill level.

The Square Wave TIG 200 provides smooth and stable AC TIG welding on aluminum and DC TIG welding on steel, stainless steel and chrome-moly. A user-friendly interface enables the operators to set it, forget it and weld. Available features, such as Pulse, provides a drumbeat-like rhythm for filler metal deposition, helps you become a better welder.


AC Frequency has a range of 60-150 (Hz) which creates a higher frequency that results in a more focused bead. AC Balance setting has a range of 60-90 (%electrode negative) that gives you an arc with higher penetration. Pulse setting has a range of 0.1-20 (pulses per second) that gives higher pulse frequency to help manage heat input and minimize material distortion.
