    New! Coolmate 3X cooler option features a 3-gallon cooling system. A flow indicator provides visual indication that the system is working. The Coolmate 3X is also equipped with an external filter to stop any foreign objects from entering the water-cooled torch cable for better flow and longer life.

    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 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+ or -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.
