Why is there porosity in welds with my Clarke Welding System?
Porosity in welds can be due to several factors: * Using an acid electrode on steel with high sulphur content. Use a basic electrode instead. * The electrode oscillates too much or workpieces are too far apart. Move edges to be welded closer together. * The workpiece being welded is cold. Move slowly at the beginning.
What to do if my Clarke Welding System has no output voltage?
No output voltage may be due to: * The machine is overheated (the red LED should be on). Wait for thermal cutout to be reset. * Internal relay has failed. Contact your nearest CLARKE dealer. * Inverter printed circuit is defective. Contact your nearest CLARKE dealer.
What to do if my Clarke Welding System has the wrong output current?
The wrong output current could be due to a defective current selector control, in which case you should contact your nearest CLARKE dealer. It may also be due to low power supply voltage. Check the mains distribution system.
How to troubleshoot unstable arc in Clarke Welding System?
An unstable arc can be caused by insufficient current. Check the condition of the electrode and the earth wire connection.
What to do if Clarke Welding System spark will not start?
If the spark won't start, check the clamp connection. If problem persists, contact your nearest CLARKE dealer, as the inverter printed circuit may be defective.
What causes high sprays in Clarke Welding System?
High sprays can occur if the electrode is too inclined. Make appropriate corrections.
Why does the electrode melt obliquely in my Clarke Welding System?
If the electrode melts obliquely, it could be because the electrode core is not centered; in this case, replace the electrode. It could also be due to a magnetic blow phenomenon; connect two earth wires to opposite sites of the work piece.
What causes profile defects in my Clarke Welding System?
Profile defects can occur if the welding parameters are incorrect, the pass rate is not related to operating parameter requirements, or the electrode is not inclined constantly while welding. Follow basic and general welding principles.
