Lincoln Electric has released their new Square Wave TIG. This general-purpose AC/DC TIG and stick machine effectively tackles steel, stainless, cro-moly, titanium and aluminum applications and many materials. The Square Wave TIG 175 features low amperage starting performance with the ability to go down to 10amps on AC or DC. The machine’s proprietary square wave TIG technology reduces tungsten spitting and resulting electrode erosion. Instead, it provides a smooth, stable AC welding arc. The standard Auto Balance control automatically delivers the optimal mix of cleaning action vs. penetration. Along with the Auto Balance control, the Square Wave TIG 175 offers a standard heavy duty foot Amptrol remote control pedal preferred by fabricators, detachable TIG torch for replacement or changes to other special application torches. The machine also includes stick welding capability. The Square Wave TIG 175 provides shielding gas pre-flow and post-flow control with built-in 0.5 second pre-flow and 15 second post-flow timers to purge and protect the weld and tungsten.
