You can choose from "constant power," "secondary constant current effective value," "primary constant current peak value," "primary constant current average value," "constant voltage," or "constant phase" to attain stable welding quality.

Over-current detection, no-power and no-voltage detection, temperature control failure detection, and self-diagnosis.

The power, the current, and the voltage can be monitored.

Eitherms or cycle can be selected.

Interrupt feature functions when a displacement amount reaches up to set level and stops current to obtain stable fusing. For this feature, it needs to be connected with a weld checker with a built-in displacement monitor and set a displacement amount of electrodes beforehand.
