INSTALLATION FLEXCUT™ 80
INPUT PLUG INSTALLATION
A 10 ft. (3m) power cord is provided with the
FLEXCUT™ 80.
Single Phase Input
Connect green lead to ground per National Electrical Code.
Connect black and red leads to power.
Wrap white lead with tape to provide 600V insulation.
Three Phase Input
Connect green lead to ground per National Electric Code.
Connect black, red and white leads to power.
In all cases, the green or green/yellow grounding wire must be
connected to the grounding pin of the plug, usually identified by a
green screw.
Attachment plugs must comply with the Standard for Attachment
Plugs and Receptacles, UL498.
The product is considered acceptable for use only when an
attachment plug as specified is properly attached to the supply cord.
POWER CORD REPLACEMENT
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 and
the connection diagrams. Failure to do so may result in
bodily injure or death.
If the input cord is damaged or needs to be replaced, the new cord
must be wired directly into the switch on the back of the machine.
Be sure to disconnect the cord from input power before working
on the machine.
Remove the sheetmetal wraparound from the
machine, loosen the strain relief on the rear of the machine, and
loosen the three input screws on the power switch as well as the
grounding nut. Remove the old cord and replace as shown below. Be
sure to torque the phillips screws on the input power switch and the
grounding nut to 18-25 in-lbs.
ALWAYS CONNECT THE GROUNDING LUG (LOCATED INSIDE THE
MACHINE) TO A PROPER SAFETY (EARTH) GROUND.
ENGINE DRIVEN GENERATOR
For use on engine drives, keep in mind the above input draw
restrictions and the following precaution.
The FLEXCUT™ 80 can be operated on engine driven generators as
long as the 230 volt auxiliary meets the following conditions:
• The AC waveform peak voltage is below 400 volts.
• The AC waveform frequency is between 45 and 65 Hz.
Lincoln Electric Vantage ® and Ranger ® engine drives meet these
specifications.
Operation of the FLEXCUT™ 80 is not recommended on engine drives
not conforming to these conditions. Such combinations may
overvoltage the FLEXCUT™ 80 power source.
GAS SUPPLY REQUIREMENTS
Supply the FLEXCUT™ 80 with clean, dry, oil-free compressed air or
nitrogen. A high pressure regulator MUST be used with a compressor
or a high pressure cylinder.
Supply pressure must be between 87-110 psi (6 - 7.6 bar) with flow
rates of at least 300 SCFH or 140 SLPM.
Air supply pressure should never exceed 110
psi or damage to the machine may occur!
The FLEXCUT™ 80 contains a built-in filter but depending on the
quality of the supply, additional filtration may be required. Be aware
that shop air systems are prone to oil and moisture contamination. If
shop air is used, it must be cleaned to ISO 8573-1:2010, Class 1.4.1.
Specify dry air when using compressed cylinders. Breathing quality
air conains moisture and should not be used.
A standard nominal 5 micron inline filter is recommended, but for
optimal performance, select a pre-filter with a 3 micron absolute
rating.
CYLINDER could explode if damaged.
• Keep cylinder upright and chained to a fixed support.
• Keep cylinder away from areas where
it could be damaged.
• Never lift machine with cylinder
attached.
• Never allow the cutting torch to touch the cylinder.
• Keep cylinder away from live electrical parts.
• Maximum inlet pressure 110 psi.
