    • 1.Ammeter/Voltmeter Display

      2.Arcforce rotary dial

      To adjust the welding parameters to the electrode type used.
      Infinite setting from rutile (soft arc) to cellulose (hard arc) electrode types.

      3.Hotstart current rotary dial

      Increased ignition current during the set hotstart period to optimise the arc ignition. Setting from 20 A to 250A.

      4.Hotstart period rotary dial

      Increased ignition current (hotstart current) flows during the period set. Setting from 0s to 2s.

      5.Welding current setting rotary dial

      Infinite setting of the welding current across the whole power range.

      2.Encoder Control



    function reliably ignites the electrode and melts perfectly to ensure the best quality even at the start of the seam.This solution makes lack of fusion and cold welds a thing of the past and significantly reduces weld reinforcement. Adjust the hot start current here and the time here.

    Arcforce correction(welding characteristics)

    Arcforce is a setting that allows you to adjust the arc to soft smooth arc to a more aggressive digging arc. Setting high is to bump up amperage when you have a really tight arc so that you keep welding.
