Troubleshooting - Husky CUT20P Guía De Uso Y Cuidado

Troubleshooting

NOTE: When yellow tripped protection/alert indicator turns on, the possible causes are 1) tripped overheat protection; 2) tripped
overvoltage protection; 3) missing outer nozzle alert; 4) missing inner nozzle and electrode tip alert. Please refer to a quali ed
electrician to check your machine.
Problem
No output when switched
on and neither indicator LED
is illuminated.
No output when switched
on and indicator LED is
illuminated.
No gas ows.
The arc does not ignite.
Insuf cient cutting
penetration.
Possible Cause
□
Loose ground clamp
connection.
□
No input power supply.
□
Tripped thermal protector by
overheating (tripped
protection/alert indicator LED
turns on).
□
Overheating caused by
environmental factor (high
room temperature or
insuf cient air ow).
□
Incorrect input voltage.
□ Plugged nozzle.
□
Blocked air supply hose.
□
Poor ground clamp
connection.
□
Too low input power.
□
Output current is too low.
□
Workpieces are too thick.
□
Cutting speed is too fast.
□
During cutting process,
plasma torch is too tilted.
□ Plasma torch consumable
parts are worn out.
□
Check and make sure the ground clamp is well attached to
the workpiece.
□
Check and make sure machine is plugged in.
□
Verify outlet output power.
□
Check the circuit breaker to see whether it is tripped or not.
Reset if necessary.
□
Reduce the duration of the cutting period, or duty cycle, or

□
Check the air supply hose (including the part inside the
cutting torch cable).
□
Check connection of ground cable to ensure it is well
connected.
□
Make sure your power source provides enough amperage
or reduce the length of your extension cord.
□ Increase the cutting current by adjusting the amperage
adjustment knob.
□
Make sure your power source provides enough amperage
or reduce the length of your extension cord.
□
Choose workpieces within the operational limits of the
cutting machine.
□
Decrease your torch travel speed.
□
Ensure your plasma torch is perpendicular to the workpiece
when cutting.
□
Check consumable parts for wear and replace worn parts.
