125 CCC .
INSTALLATION
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
125 CCC Power Switch OFF when
connecting power cord to input power.
SELECT SUITABLE LOCATION
®
Place the FLEXCUT
125 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 can 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.
CAUTION
Keep machine dry.
Shelter from rain and snow. Do not place on wet ground or
in puddles.
LIFTING
®
The FLEXCUT
125 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
125 CCC cannot be stacked.
TILTING
®
The FLEXCUT
125 CCC must be placed on a stable, level surface so
it will not topple over.
HIGH FREQUENCY INTERFERENCE PROTECTION
®
The FLEXCUT
125 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 125 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
125 CCC is rated for 380 VAC through 575 VAC input
voltages, 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.
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.
