Weld stability has been much improved!
Secondary current, constant voltage, constant power, and combination of voltage and current can be selected to optimize weld conditions.
With an optional displacement monitor, it is possible to weld with uniform penetration amount all the time.
Weld condition setting and monitoring can be done with an PC through RS-232C/RS-485.
The welding current rises 6 times faster than that with the conventional welders*.
* Compared to the conventional model, IP-217A
Five welders can be controlled by one power supply connecting an external transformer switch.
Due to the fast current rise, this power supply support for short-time/large-current welding applications.
The welding transformer supports 3-phase 200-240V or 380-480V (configured at the factory), so that it can take different power spec world wide.
Current ripple is reduced to 1/3 of that with the conventional model.* With the same effective current, this model can suppress the peak current in low value unlike the conventional models.
With this function, the actual wave form is judged good/bad comparing with an "envelope" waveform, which provides the permissible range. The envelope waveform is determined based either on a standard waveform (average welding waveform) or on a monitored waveforms.
