Request a Quote
Features
- Advanced IGBT inverter technology;
- Designed with self-locking and non-self-locking functions for argon arc welding;
- Manual arc welding supports vertical-down welding with cellulose electrodes;
- Automatic protection functions for overcurrent, overvoltage, undervoltage and overload;
- High efficiency and low no-load loss, can save more than 1/3 power comparing to conventional welders;
- Automatic compensation for mains voltage fluctuations, strong resistance to voltage fluctuation (V±15%);
- Easy arc starting, low noise level, stable and reliable arc, good weld formation;
- For welders of over 550A, can implement carbon arc gouging, suitable for welding of stainless steel, alloy steel, titanium, etc.;
- Two welding processes can be accomplished in one machine, i.e. argon arc welding and manual arc welding;
Standard Configurations
