Power/Air/Water Requirements - Lincoln Electric Torchmate 4400 User Manual

Power/Air/Water Requirements

Please refer to the FlexCut operators manual for complete installation and operation guidelines. Only a qualified
electrician should connect the input leads to the Torchmate 4400/4800 CNC unit and FlexCut Plasma unit.
Connections should be made in accordance with all local and national electrical codes. Failure to do so may result in
bodily injury or death.
The FlexCut 80 is rated for 208 VAC through 575 VAC input voltages, single or three phase and 50 or 60 Hz. The
FlexCut 125 is rated for 380 VAC through 575 VAC input voltage, three phase only and 50 or 60 Hz. Before connecting
the machine to power, be sure the input supply voltage, phase and frequency all match those listed on the machine
rating plate.
The FlexCut 80 automatically senses and adjusts to work with any input voltage, phase or frequency listed on the
rating plate. No reconnect switch settings are required. The power supply cord is supplied without an attachment
plug to accommodate single phase or three phase installations.
Warning:
The FlexCut on/off switch
is not intended as a service
disconnect for this equipment.
Only a qualified electrician
should connect the input leads
to the Torchmate 4400-4800.
The Torchmate 4400-4800 CNC machine requires clean, dry, oil-free compressed air or nitrogen. A high pressure
regulator MUST be used with a compressor or high pressure cylinder.
Supply pressure must be between 87-110 psi (6-7.6 bar) with flow rated rates of at least 300 SCFH or 140 SLPM.
AIR SUPPLY PRESSURE SHOULD NEVER EXCEED 110 PSI OR DAMAGE TO THE MACHINE MAY OCCUR!
A standard nominal 5 micron in-line filter is recommended, but for optimal performance, select a pre-filter with
a 3 micron absolute rating. Air must be supplied to the plasma with 3/8" inside diameter tubing and 1/4 NPT quick
disconnect coupler. Air lines should be run as to not create a trip hazard.
Water should be installed in the table pan before operation. Rust inhibitors such as non sodium nitrite based
products may be used as a corrosion inhibitor in CNC plasma water tables. Operators are encouraged to use a
readily available product designed for use in CNC plasma tables.
Water Capacity
• 4400 models hold approximately 60 gals or 230 liters.
