If however, having followed the instructions in this booklet carefully you still encounter problems, the following points should help identify and resolve them. DEFECT CAUSES SUGGESTIONS Spark will not start Bad clamp connection. Inverter PCB defective. Check clamp connection. Contact your nearest CLARKE dealer. No output voltage Overheated machine Wait for thermal cutout to be reset. Internal relay has failed. Contact your nearest CLARKE dealer. Inverter PCB defective. Contact your nearest CLARKE dealer. Wrong output current Current selector control is defective. Contact your nearest CLARKE dealer. Low power supply voltage. Have electrician check the mains supply. Porosity of welds Acid electrode on steel with high sulphur content. Electrode oscillates too much. Workpieces are too far apart. Workpiece being welded is cold. Use basic electrode. Move edges to be welded closer together. Move slowly at the beginning. Cracks in weld Material being welded is dirty (e.g.oil, paint, rust, oxides, moisture). Incorrect current/voltage. Clean workpiece before welding is an essential method of achieving neat weld beads. Also increase current output. Poor penetration Low welding current, high welding rate, Poor electrode inclination angle or too far from workpiece. Ensure operating parameters are regulated and improve preparation of work pieces. Profile defects Welding parameters are incorrect. Pass rate is not related to operating parameter requirements. Electrode not inclined constantly while welding. Follow basic and general welding principles. |
