HIGH FREQUENCY WARNINGS

SPECIAL PRECAUTIONS ARE REQUIRED WHEN USING PLASMA,

TIG OR ANY WELDING PROCESS THAT USES HIGH FREQUENCY

TO STRIKE AN ARC.

WARNING: HIGH FREQUENCY CAN EFFECT MACHINE

OPERATION AND THEREFORE, WELD QUALITY

Read the precautions below before installing and using the equipment.

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 separa-
tion 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 interference.

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.
