Grounding Requirements
IMPORTANT GROUNDING TEST
VERIFY BEFORE OPERATING THE PLASMA CUTTER
To avoid possible damage to electronic components, motors or the PC, it is imperative
that good grounding be verified prior to operating the plasma generator. Failure to
properly ground the machine will void the warranty and may cause costly damage to the
drive system.
The plasma arc produced by this plasma torch on this machine is controlled
lightning. Proper grounding serves as a lightning rod to provide a predetermined and
safe path for electrostatic discharge. Improper grounding may result in electronic
component failure, electric shock, and possibly death.
Tin Knocker strongly recommends that the customer install a ground rod into the earth
within 12 feet of the machine.
After Installing the ground rod run a large (#6) ground wire from the plasma leads and
table frame to the ground rod. Use a ground lead (at least #12) for the 110 circuit that
drives the PC and control system to this same ground. See illustration.
All grounding wires should be short in length and larger than 8 awg wire.
Preferred grounding procedure is shown on the next page.
