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 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.
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.
