The Latest IGBT Technology

IGBT is a bipolar transistor with an insulated gate electrode. This semi-conducting device is being increasingly used in power electronics because it combines the advantages of two transistor types: the easy controls of the field effect transistor and the fast switching and high breakdown voltage of the bipolar transistor. The IGBT also offers some robustness against short circuits because it limits the electrical continuity.

Featuring Hot Start

Hot Start automatically boosts the tension at the ignition of the arc, this function facilitates the electrical arc ignition. After ignition, the unit automatically returns to the pre-set voltage.

Anti-Stick

This function helps to prevent overheating of the electrode by switching off the welding current when the electrode sticks to the material.

MMA Arc Welding

MMA is electrode welding with a coated electrode.

  1. g.cowcher

    This is a very good little MMA inverter
    I purchased this to weld 2″x1/8″ flat bar frames
    with 1/2″ rebar supports (10 in all)
    using 2.5 electrodes
    2″long fillet welds x 4 and 6 rebar each frame
    did a very good job with out cutting out
    I’m a retired coded welder class 1 ASME 9 G6
    of 50 years experience

  2. michael.linsell

    Great universal welder, bought through Manomano.
    Full kit ready to weld away.
    Worthy ***** review.

  3. Tim Shaw

    This is ideal for the jobs I need doing,repairing gates, fences etc as well as making some tools for the garden, the mask that comes with it is a bit crap better to invest in a budget nod helmet. But apart from. That excellent
