• DC+/DC-: Improved TIG starting. Now starts DC(-) to maintain a sharp tungsten. • Lift-Arc start provides AC or DC arc starting without the use of high frequency. • Adjustable AC output frequency allows the operator to focus the arc minimizing the heat affected zone. • Extended AC Balance Control helps maintain a pointed tungsten to direct the arc in the weld joint. • Independent amplitude/amperage control allows EP and EN amperages to be set independently to precisely control heat input to the work and electrode. • Multiple Waveshapes: Standard Squarewave for fast travel speeds and excellent puddle control, Soft squarewave for a soft buttery arc with maximum puddle control and good wetting action, Sine wave for a traditional softer sounding arc, Triangular wave to reduce the heat input into the weld at low amperage. • MIX TIG: we can get an excellent Arc Concentration, can be carried out the excellent welding performance from thin to thick plate.
