SAFETY PRECAUTIONS
ELECTRIC SHOCK can kill.
• Turn the input power OFF at the
disconnect switch or fuse box
and discharge input capacitors
before working inside the equip-
ment.
• Do not touch electrically hot parts or electrodes with
your skin or wet clothing.
• Always connect the 80 grounding terminal (located
on the side of the Case Back Assembly) to a good
electrical earth ground.
• Always wear dry, insulating gloves.
• Turn the 80 Power Switch OFF when connecting
power cord to input power.
Only qualified personnel should install, use, or ser-
vice this equipment.
SELECT SUITABLE LOCATION
Place the PRO-CUT 80 where clean cool air can freely
circulate in through the rear louvers and out through
the front/bottom opening. Dirt, dust or any foreign
material that can be drawn into the machine should be
kept at a minimum. Failure to observe these precau-
tions can result in excessive operating temperatures
and nuisance shutdown of the machine.
A source of clean, dry air or nitrogen must be supplied
to the PRO-CUT 80. Oil in the air is a severe problem
and must be avoided. The supply pressure must be
between 80 and 150 psi. The flow rate is approximate-
ly 6.0 cfm (170 l/min.). Failure to observe these pre-
cautions could result in excessive operating tempera-
tures or damage to the torch.
STACKING
The PRO-CUT 80 cannot be stacked.
LIFTING AND MOVING
FALLING EQUIPMENT can cause
injury.
• Do not use the pull handle on the
optional undercarriage, if installed,
to lift the machine. This handle is
not designed to support the full
weight of the machine. Using it to
lift the machine could cause per-
sonal injury or damage to the
machine.
• Either the front or rear handles or both may be used
to lift or move the machine.
TILTING
The PRO-CUT 80 must be placed on a stable, level
surface so it will not topple over.
HIGH FREQUENCY INTERFERENCE
PROTECTION
The PRO-CUT 80 employs a touch start mechanism
for arc initiation. This eliminates high frequency emis-
sions from the machine as compared with spark gap
and solid state type high frequency generators. Keep
in mind, though, that these machines may be used in
an environment where other high frequency generating
machines are operating. By taking the following steps,
you can minimize high frequency interference.
• Make sure the power supply chassis is connected to
a good earth ground. The work terminal ground does
NOT ground the machine frame.
• Keep the work ground clamp isolated from other work
clamps that have high frequency.
• If the ground clamp cannot be isolated, then keep the
clamp as far as possible from other work clamp con-
nections.
• When the machine is enclosed in a metal building,
several good earth driven electrical grounds around
the periphery of the building are recommended.
Failure to observe these recommended installation pro-
cedures may cause improper function of the Pro-Cut or
possibly even damage the control system or power
supply components.
