Miller Syncrowave 250 DX TIG Welder

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 consumable storage located on the front panel allows the operator to store and readily access the needed consumables to be more productive. Fan-On-Demand™ operates only when needed — reducing noise, power consumption, and the amount of airborne contaminants pulled through the machine. Lift-Arc™ start provides TIG arc starting without the use of high frequency. LVC™ Line Voltage Compensation keeps output of the power source constant regardless of fluctuation in input power ± 10%. Adaptive Hot Start™ for Stick automatically increases output amperage at the start of a weld should the start require it and prevents the electrode from sticking and creating an inclusion.
