Why is there no welding current in my Lampert PUK04?
- JJasmine HardinAug 20, 2025
The absence of welding current in your Lampert Welding System could stem from several factors. It may be due to an interrupted mains cable, so check the cable and voltage. The device fuse might be blown and need replacing with an identical one. Welding cable connections could be interrupted, so inspect those connections. There might be poor or zero contact with the workpiece; ensure a solid connection, fastening contact clamps directly to the workpiece. A leakage current fault could also be the cause; try switching the device off and on again. If the issue persists, arrange for servicing.
