SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK CAN KILL.
• Only qualified personnel should install
this machine.
• Turn the input power OFF at the
disconnect switch or fuse box and
discharge input capacitors before working inside the
equipment.
• Do not touch electrically hot parts.
®
• Turn the FLEXCUT 80 CCC Power Switch OFF when
connecting power cord to input power.

SELECT SUITABLE LOCATION

Place the FLEXCUT ® 80 CCC where clean cool air can freely circulate
in through the rear of the machine and out through the front and side
louvers. Maintain at least 10 inches of space on all sides of the unit.
Dirt, dust, or any foreign material that be drawn into the machine
should be kept to a minimum. A properly installed machine will allow
for dependable service and reduce periodic maintenance time. Failure
to observe these precautions may result in excessive operating
temperatures and nuisance shutdowns of the machine.

LIFTING

The FLEXCUT ® 80 CCC power supply should be lifted by two people
or a hoist. In order to prevent damage, the power supply should be
lifted by both handles while keeping the unit as horizontal as possible.
Only hoisting straps approved for the weight of the machine should be
used.

STACKING

The FLEXCUT ® 80 CCC cannot be stacked.

TILTING

The FLEXCUT ® 80 CCC must be placed on a stable, level surface so it
will not topple over.

HIGH FREQUENCY INTERFERENCE PROTECTION

The FLEXCUT ® 80 CCC employs a touch start mechanism for arc
initiation which eliminates high frequency emissions 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, high frequency
interference into the FLEXCUT
(1) Make sure the power supply chassis is connected to a good earth
ground. The work terminal ground does NOT ground the machine
frame.
(2) Keep the work clamp isolated from other work clamps that have
high frequency.
(3) If the work clamp cannot be isolated, then keep the clamp as far
as possible from other work clamp connections.
(4) When the machine is enclosed in a metal building, several good
earth driven grounds around the periphery of the building are
recommended.

INPUT CONNECTION

WARNING
Only a qualified electrician should connect the input leads to
®
the FLEXCUT 80 CCC. Connections should
be made in accordance with all local and
national electrical codes and the
connection diagrams. Failure to do so may
result in bodily injure or death.
The FLEXCUT ® 80 CCC is rated for 208 VAC through 575 VAC input
voltages, single or three phase and 50 or 60 Hertz. Before connecting
the machine to power, be sure the input supply voltage, phase and
frequency all match those listed on the machine's rating plate.
The FLEXCUT ® 80 CCC automatically senses and adjusts to work with
any input voltage, phase or frequency listed on the rating plate. No
reconnect switch settings are required.

MACHINE GROUNDING

The frame of the welder must be grounded. A ground terminal
marked with a ground symbol is located next to the
input power connection block.
See your local and national electrical codes for
proper grounding methods.
WARNING
®
The FLEXCUT 80 CCC ON/OFF switch is not intended as a
service disconnect for this equipment. Only a qualified
electrician should connect the input leads to the FLEXCUT
80. Connections should be made in accordance with all
local and national electrical codes. Failure to do so may
