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. Maxi-
mize 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 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 recom-
mended 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.
HIGH FREQUENCY WARNINGS
WARNING: HIGH FREQUENCY CAN EFFECT MACHINE
OPERATION AND THEREFORE, WELD QUALITY.
SPECIAL PRECAUTIONS ARE REQUIRED WHEN USING PLASMA,
TIG OR ANY WELDING PROCESS THAT USES HIGH FREQUENCY
TO STRIKE AN ARC.
Read the precautions below before installing and using the equipment.
