5 – Maintenance and Troubleshooting
Common cutting issues
Problem Solution
The circuit breaker trips
while you are cutting.
• Turn down the cutting current. See Step 3 – Adjust the output current on
page 43.
• Operate the system on a 240 VAC input circuit whenever possible.
• Avoid stretching the arc. Drag the torch on the workpiece. See Edge start
on a workpiece on page 50.
• Operate the system without using an extension cord. If you must use an
extension cord, use a heavy conductor cord of the shortest possible
length. See Extension cord recommendations on page 29.
• Make sure nothing else is drawing power on the same circuit.
The cut quality is poor. • Make sure the torch is being used correctly. See Hand torch operation on
page 48.
• Make sure the correct consumables are installed. See Consumable use
on page 33.
• Inspect the consumables and replace as necessary. See Inspect the
consumables on page 55.
• Loosen the consumables about 1/8th of a turn and try again.
• Make sure the work lead connection is secure and there is no damage to
the work lead.
• Operate the system without using an extension cord. If you must use an
extension cord, use a heavy conductor cord of the shortest possible
length. See Extension cord recommendations on page 29.
The torch does not cut
completely through the
workpiece.
• Make sure the torch is being used correctly. See Hand torch operation on
page 48.
• Inspect the consumables and replace as necessary. See Inspect the
consumables on page 55.
The arc does not transfer
to the workpiece.
• Clean the area where the ground clamp contacts the workpiece to ensure
a good metal-to-metal contact.
• Inspect the ground clamp for damage and repair it if necessary.
• Move the torch closer to the workpiece and fire the torch again. See Hand
torch operation on page 48.
The arc blows out but
re-ignites when the torch
trigger is pulled again, or
the arc sputters and
hisses.
• First, inspect the consumables for signs of moisture. If moisture is present,
fire the torch approximately 5 times in succession.
• If the problem persists, inspect and replace the consumable parts if they
are worn or damaged. See Inspect the consumables on page 55.
