Weld Power Supply (Clean Spot Series)

＜Transistor Resistance Weld Power Supply (PW-30D)＞

Resistance Weld Power Supply "PW-30D" is born as the crystallization of our 30 years of weld technology. By combining the use of our designed weld-head, precise and minute weld can be achieved.

Stable Output (no intermittent output)
High quality weld under short period of time.
Continuous high speed feedback control for Flowing voltage/current
10 times faster Control response Speed compared to Inverter type power supply.
Precise rise/fall control
Fewer explosions caused by rapid rise of current.
3 control selections
Selection from "Constant Voltage", "Constant Power", "Constant Current" can be made according to work material and shape.
Small EMI(Electromagnetic Interference) level
Less electromagnetic radiation from power supply. (Less interference to other equipment.)
RS232C is equipped.
Can output weld current and weld voltage data. Also can change the weld setting from outside.

New product is added to our Power supply family. Arc Weld Power Supply "PW-05Arc" which uses the arc discharge for welding. It enables the satisfying weld even though the material and shape are difficult for spot weld.

Pre-heat function : electrical contact before arc discharge
Equalize resistance of contact surface to minimize the fluctuation of electrical contact current.
Start arc discharge between two subjects separated by magnetic force.
Less influence of electromagnetic interference caused by high voltage discharge.
Arc discharge main circuit is independent from magnet control circuit which triggers the arc weld.
The space between subjects for arc discharge is stable (fixed) because of independent magnetic control circuit, thus allows the stable discharge.
Constant current property is achieved within discharge area.
The space for arc current is stable (fixed), thus stable discharge is achieved.
Less fluctuation of the current during discharge, which makes the weld stable.
Keypad to make setting of arc current and output time
Easy arc discharge output condition setting.
Charging voltage/time can be controlled by Magnet control circuit
Easier to find the best weld condition by making change on Supply voltage/time by rotation POT.
Output Current/Voltage of magnet and arc discharge to weld wave monitor terminal(rear panel)
Magnet and arc current, voltage, timing can be visualized by use of oscilloscope
