Troubleshooting
The power indicator light does not light up
1、Incoming line380VThe power is not turned on.
2, The power indicator light is broken.
1, Troubleshoot the incoming power supply failure.
2, Replace the indicator light with a new one.
The power indicator light is on and the controller does not work.
1、The travel switch is not turned on.
2、The travel switch is damaged.
3、The controller is damaged.
1、Turn on the travel switch.
2、Replace the travel switch.
3、Replace the controller.
The controller is active, but the current on the workpiece is too small or there is no current.
1、The surface of the workpiece is severely oxidized or contaminated.
2、Electrode is severely oxidized
3、Each connection point is severely oxidized or the screws are loose.
4、Damage to secondary insulation
5、Damaged thyristor
6、Controller damaged
1、Remove oil stains from workpiece surface
2、Polish the electrode surface oxide
3、Polish each connection point and tighten the screws
4、Re-insulate the secondary insulation
5、Replace thyristor
6、Replace controller
The solder joints burned through and there was serious spatter between the electrodes.
1、Current adjustment is too large
2、Power-on time is too long
3、Electrode pressure is too small
4、The surface of the electrode tip is serious
1、Turn down the current
2、Shorten power-on time
