For DC spot welding/fusing ISB-600A

Various weld schedules and control methods for meeting your applications!
Model : 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.
