POSSIBLE CAUSES
Torch incorrectly connected to the power source.
Incorrect compressed-air pressure.
Missing consumable part (nozzle, contact tip electrode
or diffuser, etc.).
Consumables are not installed correctly.
Earth clamp not properly connected (if disconnected
after a few seconds of cutting).
Inappropriate cutting-feed speed.
The distance between workpiece and torch's nozzle is
too great.
The compressed-air supply has been cut off.
Damaged consumable in the torch.
Insufficient air pressure.
The cutting-feed speed is too fast.
Impurities or moisture in the compressed air.
Soiled cutting surface.
The cutting-feed speed is too fast.
Incorrect compressed-air pressure.
The cutting current is too low for the thickness of the
workpiece.
Torch not held perpendicular to the surface of the
workpiece.
Consumables incorrectly fitted in the torch (loose
nozzle, etc.).
The cutting current is too low for the thickness of the
workpiece.
SOLUTIONS
Check the torch's conenction to the power source.
Adjust the air pressure to the recommended value.
Replace missing parts.
The electrode is not in contact with the contact tip.
Check that the earth clamp is connected to one of the
sheet metal's clean surfaces to be cut effectively.
Adjust the cutting speed.
Bring the torch closer to the workpiece.
Check the compressed-air supply.
Inspect the torch's consumable parts and replace them.
Adjust the air pressure.
Adjust the cutting speed.
Check the power source's air filter.
Clean and strip the surface of the sheet metal to be cut.
Adjust the cutting speed.
Adjust the air pressure to the recommended value.
Adjust the cutting current value on the power source.
Improving torch support.
Readjust the fitting and tightening of consumables.
Adjust the cutting current value on the power source.
