6 TROUBLESHOOTING WARNING There are extremely dangerous voltage and power levels present inside this unit. Do not attempt to diagnose or repair unless you have had training in power electronics measurement and troubleshooting techniques.
6.1 Power lamp and temperature lamp is on.
6.1.1 Check for blocked air flow around the unit and it is in good working order.
6.1.2 Fan blocked – check and correct condition.
6.1.3 Unit is overheated – allow it to cool down for at least 5 minutes and make sure the unit has not been operated beyond Duty Cycle limit. Refer to Technical Information in Section 2. 6.1.4 Faulty components in unit – return to your distributor for repair or have a qualified technician repair using the Service Manual.
6.2 Torch fails to ignite the arc when torch switch is activated.
6.2.1 System is in ‘SET’ mode – change to ‘RUN’ mode.
6.2.2 Faulty torch parts – inspect torch parts and replace if necessary.
6.2.3 Gas pressure is too high or too low – adjust to correct pressure.
6.2.4 Faulty components in unit – return to your distributor for repair or have a qualified technician repair using the Service Manual.
6.3 No cutting output. Torch is activated, power source is on, gas flows and fan operates
6.3.1 Torch not properly connected to power supply – check that torch leads are properly connected to power supply. 6.3.2 Work cable not connected to work piece, or connection is poor – make sure that work cable has a proper connection to a clean, dry area of the workpiece. 6.3.3 Faulty components in unit – return to your distributor for repair or have a qualified technician repair using the Service Manual. 6.3.4 Faulty Torch – return to your distributor for repair or have a qualified technician repair using the Service Manual.
6.4 Low cutting output
6.4.1 Incorrect setting of CURRENT control – check and adjust to correct setting.
6.4.2 Faulty components in unit. Return to your distributor for repair or have a qualified technician repair using the Service Manual.
6.5 Difficulty Starting
6.5.1 Worn torch parts (consumables). Shut off input power. Remove and inspect torch shield cup, tip and electrode. Replace electrode or tip if worn. Replace shield cup if excessive spatter adheres to it.
12
STEALTH DIGI-CUT 60-1
6.6 Arc shuts off during operation. Arc will not restart when torch switch is activated.
6.6.1 Power Supply is overheated (OC/OT lamp is lit) – allow unit to cool down for at least 5 minutes. Make sure the unit has not been operated beyond Duty Cycle limit. Refer to Section 2 for duty cycle specifications. 6.6.2 Gas pressure too low (the TIP/GUN/GAS lamp is lit when torch is switched on) – check source for at least 4bar/60psi and adjust as required (the machine cover will require opening). 6.6.3 Torch consumables worn – check torch shield cup, tip, starter element and electrode. Replace as required. 6.6.4 Faulty components in unit – return to your distributor for repair or have a qualified technician repair using the Service Manual.
6.7 No gas flow, the power lamp is on and fan operates
6.7.1 Gas not connected or pressure too low – check gas connections. Adjust gas pressure to correct setting. 6.7.2 Faulty components in unit – return to your distributor for repair or have a qualified technician repair using the Service Manual.
6.8 Torch cuts but low quality
6.8.1 CURRENT control set too low – increase current setting.
6.8.2 Torch is being moved too fast across workpiece – reduce cutting speed.
6.8.3 Excessive oil or moisture in torch – hold torch 3 mm from clean surface while purging and observe oil or moisture buildup (do not activate torch). If there are contaminants in the gas additional filtering may be required.
