4. Feed the end of the torch leads through the hole in the
front panel in the following order:
• Control Cable
• Gas lead
• Pilot Lead
5. Place the strain relief into the hole and secure with the
nut removed in Step 3 above.
6. Connect the torch gas/power lead fitting onto the Gas/
Power Lead Connection.

3.10 Work Cable And Ground
Connections
A. Electromagnetic Interference (EMI)
High frequency pilot arc initiation generates a certain
amount of electromagnetic interference (EMI), commonly
called RF noise. This RF may interfere with other elec-
tronic equipment such as CNC controllers, etc. To mini-
mize RF interference, follow these grounding procedures
when installing mechanized systems:
B. Creating an Earth Ground
1. Install a ground wire (not included) between the sys-
tem and a solid earth ground (also called star ground).
To create a solid earth ground, drive a 1/2 in (12 mm)
diameter copper rod approximately 6 - 8 ft (1.8 - 2.4
m) into the earth so that the rod contacts moist soil
over most of its length. The required depth will vary
depending on location. Locate the rod as close as pos-
sible to the power supply. The work table should be
connected to the same earth ground as the power sup-
ply.
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 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.
