The ZX7 series uses the Siemens IGBT modules, PWM inverter technology,with high reliability.
The main function characteristics:
Adopt IGBT inverter technology, high frequency, high efficiency, low noise,good anti-interference performance, stable arc.
Having perfect over-voltage, under voltage automatic protection function,overheat, over current, overload, safe and reliable.
- thrust current can be adjusted continuously, arc force strong, anti sticking.
- use for up to 50-100 meters welding cable, stable.
- suitable for acid, alkali, cellulose and other types of welding rod, welding in all positions.
