The Square Wave Lincoln TIG 200 welding machine from Lincoln Electric offers multi-process TIG and stick welding capabilities.
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. Lincoln says the unit combines an easy-to-use interface for fast set up with built-in advanced features. A pulsed TIG feature provides a rhythm for filler metal deposition, and AC frequency control allows users to adjust the machine for a wider or more narrow arc profile when TIG welding on aluminum.
