    The short-circuiting metal transfer mode

    The short-circuiting metal transfer mode is the low heat input mode of metal transfer for GMAW and has higher electrode efficiencies, 93% or more. The low heat input reduces weldment distortion and makes it ideal for sheet metal thickness materials.


    Use the spot and cycle arc timer you can easily control the welding time and the stitch length during the continue spot welding jobs. Spot/Stitch mode provides a quick and effective means for spot welding mild, galvanized or stainless materials. Very useful for the car body repairs.


    • 4-Rolls wire-feeder with strong feeding motor. Four-roll drive systems deliver the electrode to the welding torch. It provides a stable wire speed and is popular for industrial applications.

    Lift TIG Mode

    • Lift TIG Modeprovides TIG arc initiation without the use of high frequency. Touch, bump or scratch the work surface with the electrode to start the arc.It also has a good result in tig welding.
