ZX7 Series Inverter DC MMA welding machine
Applications & Featuer
1. It adpots MOSFET invert technology, high frequency arc start design
2. It can balance automatic when voltage is waving, with high resist to electrical wave ± 15%
3. It has high efficiency, small unload loss, save more 41% than traditional welder
4. It is small and light, easily work in aloft work
5. It is easily arc, small flash, low noise, stable welding are, wonderful welding shape
6. With inner installing protective circuit of over-heat, over-current, over-voltage and under-voltage, working safe is reliable
