The cut settings are not correct.
One or more of the following settings is not correct:
Arc current
Arc voltage
Travel speed
Motion delay
Gas flow rates
Initial torch height
Use the correct settings for the type and thickness of the metal that you are cutting. Refer to the cut charts
in the XPR Cut Charts Instruction Manual (809830).
The cutting material is magnetic.
When possible, do not cut metal that is magnetic or that can easily become magnetic. For example, do not
cut armor plate that has a high nickel content.
Cutting faults that can occur frequently
Hypertherm recommends these steps when you have one of these cutting problems.
The pilot arc starts but does not transfer to the workpiece.
Make sure that the work cable is correctly connected to the cutting table and is fully tightened.
Lower the torch so that it is closer to the workpiece.
Make sure that the system is not in a fault condition.
Refer to Diagnostic codes on page 278.
The plasma arc does not cut completely through the workpiece, and there is too much
sparking on top of the workpiece.
Increase the arc current.
Refer to the XPR Cut Charts Instruction Manual (809830).
Decrease the cut speed.
Refer to the XPR Cut Charts Instruction Manual (809830).
Replace consumables that are worn or have damage.
