8. TROUBLE SHOOTING
Thermal overload
If the pump, fan (and compressor) are working but the green READY lamp is not lit, the
thermal overload protection is active.
Let the machine cool down while switched on until the lamp lights. Now the machine is in
working order.
Malfunction
If the pilot arc does not strike:
• check and, if necessary, change nozzle, electrode and electrode insulator.
• check and, if necessary, adjust inlet air/gas pressure to 3,5-4 bar.
• If possible, check air/gas flow, approx. 18 l/min. Too high air/gas flow will
prevent the pilot arc from striking.
If the pilot arc is not stable:
• too high air/gas flow, adjust inlet pressure to 3,5-4 bar.
• the machine is working two-phase, check mains fuses.
Inferior performance or cutting quality:
• check inlet air/gas pressure, 3,5-4 bar.
• inspect torch body and hose assembly for damage and leaks.
• check nozzle, electrode and electrode insulator.
• check earth lead connection. If necessary, clean it from dirt, paint and oxide.
