For DC spot welding/fusing ISB-600A
- ◆Interrupt feature
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.
- ◆Six kinds of control methods
Select an optimal control method for an application: Primary current effective value control, secondary current effective value control, secondary power effective value control, Primary current peak value control, secondary voltage effective value control, and constant phase control.
- ◆Three kinds of monitoring
Current, voltage, or power can be monitored.
- ◆Safety features
Overcurrent detector, no-current/no-voltage detector, heat abnormality detector, and self-check feature protect your safety.
- ◆Two kinds of welding time unit
ms or cycle can be selected.
