For DC spot welding/fusing IS-800A．IS-1400A
- ◆Primary current PEAK control enables detailed parameter settings.
The control features below are only available when Primary current PEAK is selected.
【Voltage compensation】
It is to adjust set values for Pulse limit depending on primary voltage fluctuation before welding.
・When 190VAC (-5%), pulse width set for Pulse limit is adjusted to increase 5%.
・When 210VAC (+5%), pulse width set for Pulse limit is adjusted to decrease 5%.【Pulse limit】
This is to limit pulse width when current is up-sloping. - ◆Ground fault and short-circuit protections ensure the safety better.
- ◆Adjustable welding frequency from 600 to 3000kHz with 100Hz increment.
- ◆Program protect feature prevents false operation due to unintended touches to the screen.
- ◆Up to the third welding is controllable. Pulsation and other control modes can be set for each welding.
- ◆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.
- ◆Duty factor and Output current
