SAFETY

PROTECT YOURSELF AND OTHERS FROM SERIOUS INJURY OR DEATH.

KEEP CHILDREN AWAY. BE SURE THAT ALL INSTALLATION, OPERATION,

MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY

ELECTRIC SHOCK can kill.

1) The equipment is not waterproof.
Using the unit in a wet environ-
ment may result in serious injury.
Do not touch equipment when wet
or standing in a wet location.

2) The unused connectors have
power on them. Always keep the
unused connectors covered with
the supplied protective panels.
Operation of the machine without
the protective panels may result in
injury.

QUALIFIED INDIVIDUALS.

EQUIPMENT DAMAGE

POSSIBLE.

1) Do not plug in the power cord without

 rstverifyingtheequipmentisOFF

and the cord input voltage is the same
as required by the machine or serious
damage may result.

2) Always verity both the pinion and
wheels are fully engaged before apply­ ing power or equipment damage may
occur.

3) Never open the equipment without

  rstunpluggingthepowercordor

serious injury may result.

4) Verify the customer-supplied power
connections are made in accordance
with all applicable local and national
electrical safety codes. If none exist,
use International Electric Code (IEC)

950.

5) Never remove or bypass the equip­ ment power cord ground. Verify the
equipment is grounded in accor­ dance with all applicable local and
national electrical safety codes. If
none exist, use International Electric
Code (IEC) 950.

READ INSTRUCTIONS.

3) Do not leave the equipment
unattended.

4) Remove from the work site and store in
a safe location when not in use.

FALLING EQUIPMENT
can cause serious
personal injury and
equipment damage.

Faultyorcarelessuserinstallationis

possible. As a result, never stand or
walk underneath equipment.

MOVING PARTS can
cause serious injury.

1) Never try to stop the pinion from mov­ ing except by removing power or by
using the STOP control.

Read the instruction manual before
installing and using the equipment.

2) Do not remove any protective panels,
covers or guards and operate equip­ ment.

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 separation between any machine cables and the plasma or welding cables.

3) Strictlyfollowthegroundingproceduresspecied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.
