Torch Shuts Off During Cut

Check Compressor Air Specifications

Reason: Air source cannot keep up with demand.

The Hypertherm plasma sources can detect inadequate air flow and will shut off the plasma arc if not enough air being provided to the unit.

• Check the specifications for your compressor to make sure that it can supply the CFM needed by your plasma source.

• Check for restrictive fittings or hoses on the air path to your plasma source.

Check Toolpath and Machine Settings to Avoid Open Water

Reason: Gaps in material being cut.

Most plasma sources will automatically shut off the arc when they encounter a gap while cutting unless placed in expanded metal / continuous pilot arc mode.

• If you are trying to cut across gaps or expanded metal, make sure your plasma source is in “expanded metal mode” and disable Torch Height Control in the PathPilot Settings menu.
