The Ultra-Arc 205 combines digital reliability and control with a simple, intuitive users interface. As a replacement for the Power-Ultra line of DC TIG, Stick and Plasma multi-process welders, the new Ultra-Arc features improved and additional TIG features, more Stick features, and a stable digitally controlled plasma cutter. As far as TIG features go, it is close in comparison to the top tier DC Power i-TIG 200T. Features are similar, but with a simplified adjustment process for TIG Pulse, featuring 3 field tested Pulse Programs which allow the user to adjust frequency, but rely on solid, proven pre-programmed settings for Pulse Amp and Pulse Time on. This allows almost anyone to operate the pulse with little additional instruction or explanation. In Stick mode, well, adjustable hot start and arc force are 2 popular features that improve stick performance over the older Power-Ultra series with up to 5/32 in. electrode capability (depending upon the class rod, some may only be 1/8 in. max). Of course, with new digital control of the Plasma, cutting quality has been improved over previous models. 2 new features available are a spot timer, and a completely new Fast Tack feature. With the improved design and performance, the Ultra-Arc has no parallel or competition for that matter. Where else will you find a plasma that is capable of cutting up to 3/4 in. included with a DC TIG and Stick welder for a price like this.
