Why is there no welding current in my Lampert PUK04?
- J
  Jasmine 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.

  Michelle FloresAug 22, 2025
  If the mains fuse blows or the automatic circuit breaker trips with your Lampert Welding System, it could be due to the mains not being sufficiently fused or an incorrect automatic circuit breaker being used. Ensure the mains are properly fused. If the mains protection trips during idling, arrange for servicing of the device.

Why does the Tungsten electrode weld to the workpiece in my Lampert Welding System?
- E
  Elizabeth WrightAug 25, 2025
  The Tungsten electrode welding to the workpiece in your Lampert Welding System is caused by excessive pressure of the electrodes on the workpiece. Touch workpiece with extremely light pressure.

Why does my Lampert Welding System have poor welding characteristics?
- T
  Troy NguyenAug 26, 2025
  Poor welding characteristics in your Lampert Welding System can be due to using the incorrect shielding gas. Use inert shielding gas (Argon 4.6).

  If the tungsten electrode melts off immediately in your Lampert Welding System, it may be because the electrode is sharpened too steeply. Use the recommended angle of grinding (approx. 15°).

Why does my Lampert PUK04 Welding System cause oxidation and rusting?
- J
  Jennifer AllenAug 30, 2025
  Oxidation and rusting with your Lampert Welding System may be due to excessive gas pressure. Reduce the flow rate; approximately 2 l/min is recommended.

What causes Tungsten inclusions in base material when using Lampert Welding System?
- J
  Jennifer LynchSep 2, 2025
  Tungsten inclusions in the base material when using your Lampert Welding System are caused by excessive pressure of the electrodes on the workpiece. Touch workpiece with extremely light pressure.

What to do if my Lampert PUK04 Welding System starts welding immediately upon touching the workpiece?
- K
  Kayla ColeSep 4, 2025
  If your Lampert Welding System begins to weld immediately when touching the workpiece (without gas pre-flow), immediately shut down the device and arrange for servicing, as this indicates a fault.

How to fix poor ignition characteristics in my Lampert Welding System?
- N
  Natalie Jordan DDSSep 6, 2025
  Poor ignition characteristics in your Lampert Welding System can be caused by the electrode being clamped loosely in the hand piece. Tighten the clamping nut in the handpiece by hand, however, tighten firmly.
