ArcGlide THC Instruction Manual 4-5
MAINTENANCE
WARNING
Do not disconnect cables when the system power is ON.
System grounding
Verify that all components of the system are individually grounded to a driven earth ground, as described in
Recommended grounding and shielding practices in the Installation section of this manual.
Check the work lead (+) connection, particularly where the work lead (+) connects to the cutting table. This must be a
good, clean connection because a poor connection can cause arc-transfer problems.
Cable connections
All cables should be checked regularly for chafing or unusual wear. If the outside insulation has been cut or otherwise
damaged, replace the cable.
In particular, check the Ohmic contact wire.
