ZX7-200 IGBT Inverter welding machine
` The inverter technology will ensure welding current highly stable at grid voltage fluctuation and arc length changing. Arc is soft and can adjust automatically.
` Small welding splashing
` Welding deposition rate is high
` Little welding deformation and good weld shaping.
` Light in weight, small in size and portable.
` A high efficiency and energy saving equipment with high power factor.
