ZX7-400 ZX7-500 ZX7-630 MMA/ARC Welding Machine

The continuously adjustable arc force in MMA mode provides effects of anti stick, unbroken arc and ensures stable arc for long cable welding
The current and voltage enjoy digital display
Wired remote control and optional wireless control
Protection against overheat, over-current and over-voltage
Optional VRD function
Full-bridge inverter soft switch control technology, double IGBT modules and quick recovery diode module
Multiple protections: Adopting multiple insulating material to protect PCB and main circuit to ensure high reliability
Work with generator (optional)

Features

Digital 32-bit chip processor,fastcomputing speed,quick arcdynamic response;
The core components use dual industrial-grade IGBT modules with high reliability;
The output current is strong,the duty cycle is60%,and the 5.0 electrode can weld for a long time;
The cable is extended to 200 meters and 5.0 welding rods can still be used for welding;（length can be customized)
It has the functions of anti-electric shock,anti-sticking strip,thrust and thermal arc initiation
Work with generator (optional)
