2.5 WORK AND GROUND CONNECTIONS

Machine torch systems are equipped with shielded torch
leads to minimize RF interference from high frequency
pilot arc initiation. Follow these grounding procedures
when installing machine torch systems:

1. Connect the ground wire (from the front panel) to a

solid earth ground, which is created by driving a
copper rod approximately 7 ft (2 m) into the earth.
Locate the rod as close as possible to the power supply.
Cut the ground wire to the appropriate length.

2. The power supply and work table should be grounded

to the same earth ground. The control device should be
grounded separately to a similar earth ground.

3. To minimize RF interference, torch leads should be run

as far as possible from any CNC components, control
lines, or primary power lines.

4. Connect work ground cables as shown (Figure 2-E).
