500A IGBT Tube Arc Inverter Welding Machine. (ARC400G)

1. The transformer core is made of high-tech material based on Nanochnology;
2. The tri-proof(water, dust and eroding proof) cooling system raised the reliability and duty-cycle of the key components;
3. Having the fan standby function;
4. With OCV as high as 70V, enables the machines to weld;
5. The duty-cycle is higher than60% when the temperature of the operation surrounding is around 40. Capable to operate outdoors;
6. The maximum output efficiency is 85%. By using the advanced electro-circuit for power factor compensation, the max power factor could be as high as 0.93;
7. EMC electro-circuit added to reduce the pollution to the electric network;
8. With digital display of the welding current and remote control for option;
9. VRD function is added to meet the European requirement.
