INSTALLATION FLEXCUT™ 125
Read entire Installation Section before installing the
FLEXCUT™ 125 .
INSTALLATION
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 Power Switch OFF when
connecting power cord to input power.
SELECT SUITABLE LOCATION
Place the FLEXCUT™ 125 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.
Keep machine dry.
Shelter from rain and snow. Do not place on wet ground or
in puddles.
LIFTING
The FLEXCUT™ 125 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
cannot
be stacked.
TILTING
The FLEXCUT™ 125 must be placed on a stable, level surface so it
will not topple over.
HIGH FREQUENCY INTERFERENCE PROTECTION
The FLEXCUT™ 125 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™ 125 can be minimized:
(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
Only a qualified electrician should connect the input leads to
the FLEXCUT 125. 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 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.
The FLEXCUT 125 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 125. Connections should be made in accordance
with all local and national electrical codes. Failure to do so
may result in bodily injury or death.
