Digital PULSE MIG WELDER
Inverter AC/DC PULSE TIG WELDER
Inverter DC TIG WELDER
Inverter CO2/MAG WELDER
Thyrster Control CO2/MAG ARC WELDER

INVERTER AC/DC Znh - 250A
The unique control developed in-house realizes perfect square wave achieving outstanding arc stability in alternating TIG welding.
FEATURE
  • High quality qelding achieved through alternating TIG welding

    The unique control developed in-house realizes perfect square wave achieving outstanding arc stability in alternating TIG welding.
    Such stability allows thin aluminum plate welding.

    Economical welder offering outstanding energy saving effects

    No need for high frequency during welding

    Welding no longer requires high freuency due to the high speed arc polarity reversal according to inverter control.

    Multi-function welding

    The Utilize 6 different welding with a single welder
    Alternating TIG, direct TIG, alternating stick, direct stick, alrernating pulse TIG, direct pulse TIG

    The application of pulse features offer outstanding performance even in dual metal sheets, different thickness plate welding and thin plate

    Maintaining arc at low currents

    Current detection control method stabilizes the arc even at low currents.
