3 – Basic System Operations
Attach the ground clamp to the workpiece
The ground clamp must be connected to the workpiece while you are cutting. If you are using the Powermax with a
cutting table, you can connect the work lead directly to the table instead of attaching the ground clamp to the workpiece.
See your table manufacturer’s instructions.
Make sure that the ground clamp and the workpiece make good metal-to-metal contact.
Remove rust, dirt, paint, coatings, and other debris to ensure the work lead makes proper
contact with the workpiece.
For the best cut quality, attach the ground clamp as close as possible to the area being
cut.
Turn on the system
Set the ON/OFF switch to the ON (I) position.
CAUTION!
Do not attach the ground clamp to the portion of the workpiece to be cut away.
