Cable connections
Examine all cables regularly for chafing or unusual wear. If the outside insulation has been cut or otherwise damaged,
replace the cable. In particular, examine the ohmic contact wire.
System grounding
Verify that all components of the system are individually grounded to a driven earth ground. See Recommended
grounding and shielding practices on page 55. Examine the work lead (+) connection, particularly where the
work lead (+) connects to the cutting machine. This must be a good, clean connection because a poor connection can
interfere with arc transfer.
WARNING!
ELECTRIC SHOCK CAN KILL
Do not disconnect cables when the system power is turned ON.
