All-in-one design features a 3-year warranty- the first and ONLY cooler in the industry with a warranty beyond one year. Syncro Start for customized arc starts allows the operator to choose from three different starting conditions to optimize the application according to tungsten diameter and material thickness. Squarewave output with AC balance control features adjustable penetration and cleaning action while increasing arc stability on various aluminum alloys, and helps eliminate tungsten spitting and arc rectification. Dual digital meters allow for quick and easy viewing of actual and preset values of amperage and voltage. Last procedure recall automatically recalls the last procedure set-up when switching polarity. Built-in preflow/postflow provides 0.2 - 5 seconds of preflow and 0 - 50 seconds of postflow. Built-in cable hangers on both sides conveniently fold out of power supply so weld cables can be stored to prevent torch or cable damage.
