Single-phase AC welding power supply
| Control type/weld mode | Multiple cycles | Single cycle | Half cycle |
| Power supply voltage fluctuation correction control | |||
| Secondary constant current control | - | - |
The max. current setting is automatically configured through test run, in order to optimise the performance of the device.
The upper and lower current limits can be fixed. This will aid the quality control.
CE and CCC supported. There are also 480V version for USA.

Timer
This displays the number to be resistered with a certain weld schedule, and the number assigned for a resistered weld-schedule for operation.
Even steel plates, that are relativery difficult to weld, can be handled by combining the 3-stage welding.
Displays the welding current settings and measured currents at "W1: Weld I" to "Weld III".
The current monitor allows you to set the upper and lower limits within ±1 to 49% in reference to the set current and it monitors the current fluctuation. The conduction angle monitor allows you to set its monitoring range between 1° to 180° and it monitors the maximum conduction angle.
Various settings can be made by selecting a mode from 0 to 5.

You can check the current timer status.
When "Pressurize" is set for tip replacement or electrode polishing, while Run is input, Pressurize is output. When "Weld" is switched Off, only the sequence operates. Switches the count On and Off with "Count".
If it is switched off while tip dressing or test opration, only the sequency will be ran.
Pressing this key while malfunction occured will deactivate malfunction status.
