Welding power supply
Welding heads
DC inverter welding power supply
You can choose from four control types, "secondary constant current," "constant voltage," "constant power" and "combination of constant voltage and current," which makes the optimum welding conditions possible.
A constant fusing penetration would become possible by an optional displacement monitoring function.
RS-232C/RS-485 (selectable) communications make it possible to set and monitor the welding configuration from an external device such as PC.
Since the welding current rises 6 times faster than that with the conventional welders*, micro workpieces can be welded in a short period of time.
Five welders can be controlled by one power supply connecting an external transformer switch.
Because of 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.
* Compared to the conventional model, IP-217A
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.

DC inverter welding power supply
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, self-diagnosis function
You can monitor the power, the current, and the voltage.
Either "ms" or cycle are chosen.
An inverter type welding power supply and a weld checker (with a displacement monitor) are connected and displacement amount at the electrode (penetration amount) is set in the weld checker. When the displacement amount reaches the set level, a signal will be sent out to trigger the interrupt function and stops the current. This enables the fusing with stable displacement.

DC inverter welding power supply
The IP100C and IP200V have built-in welding transformers.
These devices are equipped with high-brightness LCD that makes it possible to see the screen clearly even in a dark atmosphere.
Normally, the setting screen is displayed, but once the welding current starts to flow, the screen will be automatically switched to current monitor display.
Even if the sheet panel gets soiled, it can be cleaned up easily to maintain a beautiful appearance at all times.
Using an externally connected PC, weld schedules can be read out and reprogrammed. In addition, monitoring data and error codes can be viewed from the PC.
DC inverter welding power supply
The frequency can be switched (600Hz, 800Hz, or 1kHz)
You can choose from "constant power," "secondary constant current effective value," "primary constant current peak value," "primary constant current average value," and "constant phase" to attain stable welding quality.
You can monitor the power, current, or voltage.

DC inverter welding power supply
The fast control enables consistent seam welding and a roll spot welding. There are three types of current control; effective value control using primary current feedback, peak value control, and constant phase control.
The frequency can be switched. (600Hz, 800Hz, or 1kHz)
The appropriate welding current could be set to meet the variation of workpieces' conditions, which differ by the positions, at the beginning, the middle and the end, as well as the variation with the number of workpieces.
