Spot Welding Machine Troubleshooting

We can't help but encounter various problems in the project of using the spot welder, so what should we do to repair and eliminate the spot welder? Let's briefly introduce it for us next. The power indicator light is on, the workpiece is not tightly welded, check whether the foot pedal travel is in place, whether the foot switch is exquisite, and whether the pressure spring bolt is adjusted properly.

There should be undesired spatters during spot welding, check whether the electrode tip is oxidized seriously, and check whether the welded workpiece is severely rusted and bad. Check if the gear of the conditioning switch is too high. (Check if the electrode pressure is too low and the welding steps are accurate.

The spot welding machine does not work when the pedal welding machine is stepped on, and the power indicator light is off to check whether the power voltage is normal; check whether the control system is normal. Check whether the contacts of the foot switch, the contacts of the AC weapon, and the split-shift switch can be exquisite or burned. The spot weld of the spot welder is severely indented and there is an extrudate to check whether the current is too large. Check whether the welding workpiece has unevenness. Check whether the electrode pressure is too high, and whether the electrode tip shape and cross section are appropriate.

When the spot welding machine is welding, the AC weapon is abnormally squeaked. Check whether the incoming voltage of the AC weapon is lower than its own release voltage by 300 volts during welding. Check whether the power lead is too thin or too long, which constitutes a too large voltage drop. Check if the network voltage is too low for normal operation. Check whether the main transformer is short-circuited and constitutes too much current.
