First, the current adopts DC output mode, and the current belongs to closed-loop control, so the current is relatively stable in output, which greatly avoids the phenomenon of virtual welding.

Second, the current, power and voltage can be monitored in real time, and the stability and consistency of welding are improved.

Third, it also has the functions of fault diagnosis such as current abnormality, network voltage overrun, monitoring value overrun and overheating, and related alarm, which can reduce the welding defect rate slightly.

Fourth, it adopts three-stage heating setting, and has the functions of slow rise and slow fall of current, which effectively solves the problem of splashing and ensures the whole stability of welding more effectively.

Five, more energy-saving, how to compare with power frequency AC spot welding machine, at least more than 50% energy can be saved.

Sixth, prolong the service life of the electrode, reduce the frequency of grinding and replacing the electrode, greatly improve the working efficiency and reduce the cost of the electrode.
