of its length. The required depth will vary depend-
ing on location (see NOTE). Locate the rod as close as
possible to the power supply. The work table should
be connected to the same earth ground as the power
supply.
NOTE
A properly installed ground rod will have a resis-
tance of one ohm or less.
2. Connect the control device (CNC) to a separate earth
ground similar to the ground rod described above.
The ground cable should be at least 12 gauge (4 mm

wire.
3. To minimize RF interference, position torch leads as
far as possible (at least 1 ft or 0.3 m) from any CNC
components, drive motors, control cables, or primary
power lines.
4. Keep torch leads clean. Dirt and metal particles bleed
off energy, which causes difficult starting and in-
creased chance of RF interference.
5. Make sure work cable and ground cables are properly
connected. The work cable must have a solid connec-
tion to the workpiece or cutting table. The connec-
tion must be free from dirt, grease, oil and paint.
