INPUT VOLTAGE SELECTION
The Flexcut™ 125 is shipped connected for 460 VAC input. To
reconfigure the machine for a different input voltage see the panel on
the rear of the unit (Figure A.2). With input power removed from the
machine, move the Auxiliary (“A”) lead from the 460V tap to the
desired input voltage. Always replace the cover when finished.
If the “A” lead is not connected to the proper voltage tap, the machine
may not power on, it may throw an error, or the fuse may open.
Should the fuse open, replace the fuse, reconnect the “A” lead to the
correct voltage and re-apply power.
GAS SUPPLY REQUIREMENTS
Supply the FLEXCUT™ 125 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 90-120 psi (6.21 - 8.27 bar) with
flow rates of at least 550 SCFH or 260 SLPM.
Air supply pressure should never exceed 130
psi or damage to the machine may occur!
The FLEXCUT™ 125 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.
See the Maintenance Gas Supply Section for information on changing
the internal filter element.
Specify dry air when using compressed cylinders. Breathing quality
air contains 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 130 psi.
CONNECTING THE GAS SUPPLY
Air or gas must be supplied to the FLEXCUT™ 125 with 3/8” inside
diameter tubing and a ¼” NPT quick disconnect coupler.
OUTPUT CONNECTIONS
The FLEXCUT™ 125 is sent from the factory with a work clamp
included. The work clamp must be securely connected to the work
piece. If the work piece is painted or extremely dirty it may be
necessary to expose the bare metal in order to make a good electrical
connection.
