WARNING
Dangerous high voltage is present when the power supply is connected to input
power. Do not connect input power or operate the power supply unless the connec-
tions cover is fastened in place.
5. Increasing the ground rod length beyond 20 - 30 ft (6.1 – 9.1 m) does not generally increase the effectiveness
of the ground rod. A larger diameter rod which has more surface area may help. Sometimes keeping the soil
around the ground rod moist by continuously running a small amount of water into it will work. Adding salt
to the soil by soaking it in salt water may also reduce its resistance. When these methods are used, periodic
checking of the ground resistance is required to make sure the ground is still good.
E. Routing Of Torch Leads
1. To minimize RF interference, position torch leads as far as possible from any CNC components, drive motors,
control cables, or primary power lines. If cables have to pass over torch leads, do so at an angle. Do not run the
plasma control or other control cables in parallel with the torch leads in power tracts.
2. Keep torch leads clean. Dirt and metal particles bleed off energy, which causes difficult starting and increased
chance of RF interference.
