Inverter DC TIG WELDER
Inverter CO2/MAG WELDER
Thyrster Control CO2/MAG ARC WELDER

INVERTER DC TIG Znh 500A-2
Capable of producing even, high=quality welding utilzing low-speed pulse.
Capable of producing high-quality welding in challenging such as different material welding, different thickness material welding, etc.
FEATURE
  • High-Speed Pulse Function

    High-speed pulse current maintains a stable arc even at low current ranges.
    The fine arc creates outstanding welding capabilities on plarforms.

    Low-Speed Pulse Function

    Capable of producing even, high=quality welding utilzing low-speed pulse.
    Capable of producing high-quality welding in challenging such as different material welding, different thickness material welding, etc.

    System eliminates high current at start minimizing dug effects at thin plate welding.

    Utilization of pulse during welding can reduce heat defrmation and is capable of high-speed thin plate welding with smooth weld beads.

    AC/DE control PCB circuit allows even finer control to produce higher quality welding.

    Replacing the conventional analog meters with digital meters allow easy confirmaing of current and voltage status.
