PRECaUTIONS:

1) Some plasma or welding cables are strong sources of high frequency interference.

NEVER lay a plasma or welding cable across the controls of the machine.

2) Always physically separate the plasma or welding cable leads from the machine

cables. For example, the plasma or welding cable leads should NEVER be bundled

with a pendant cable or the machine power cord. Maximize the separation between

any machine cables and the plasma or welding cables.

3) Strictly follow the grounding procedures specified for the plasma or welding unit.

NOTE: Some plasma and welding units produce exceptionally large amounts of high

frequency noise. They may require a grounding rod be driven into the earth within six

feet (2 meters) of the plasma or welding unit to become compatible with an automatic

cutting or welding process.

4) If the high frequency is produced using a spark gap, adjust the points so the gap is as

small as possible. The larger the gap, the higher the voltage and the higher the inter-

ference.

5) Some plasma or welding units will inject high frequency interference into the AC

power line. Use separate power line branches whenever possible to power the

plasma or welding source and the machine. Do not plug them into the same outlet

box.

6) High frequency noise may enter the machine through the plasma or welding supply

remote contactor leads. Some plasma and welding sources can produce noise spikes

of up to several thousand volts. These sources are not compatible with automated

cutting and welding equipment. It is recommended that the remote contactor leads on

these plasma or welding sources not be connected to the machine. An alternate

solution is to purchase a separate remote contactor isolation box.
