  • 1. The output characteristics are similar to AC welding, the arc is strong and arc rigidity is better.
    2. High Max output voltage, stable against voltage fluctuation.
    3. Inner-loop control for quick system respondence.
    4. Peak current control made make the power devices stable against frequent short circuit shocks.
    5. IGBT parallel connection longer the life.
    6. Arc thrust function, improve the metal transfer
    7. Hot arc ignition function.
    8. Insulation varnish over the PCB.
    9. Easy to operate, precise output.
    10. Digital display
    11. Advanced inverter technology, compact, light and energy saving.
