The new Square Wave® TIG 200 welding machine from Lincoln Electric offers a multi-process TIG and stick welding experience for craftsmen, small shop fabricators, makers, motorsports enthusiasts and hobbyists. Users can perform AC TIG welding on aluminum and DC TIG welding on steel, stainless and chrome-moly when precision and bead appearance are important. Users can also switch to stick welding when working with thicker materials or welding outdoors.
 
The Square Wave TIG 200 combines an easy-to-use interface for fast set up with built-in advanced features. A pulsed TIG feature provides a drumbeat-like rhythm for filler metal deposition, making you a better welder – faster. AC frequency control allows users to adjust the machine for a wider or more narrow arc profile when TIG welding on aluminum. Adjustable AC balance provides more cleaning action on aged aluminum and helps maximize penetration on thicker aluminum materials.
 
The Square Wave TIG 200 truly allows you to Take it Everywhere, Plug in Anywhere™.
Portable and convenient to use, the machine plugs into standard 120V or 230V input circuits and weighs only 46 pounds (21 kilograms).
