POWER SUPPLY CONNECTION
The machine must be connected to a Line-Neutral system with a "PE" protected grounding wire. Check
that the relevant socket terminal is actually connected to the distribution system grounding.
CONNECTION TO GROUND CABLE
Connect the dinse plug to the socket and the work cable clamp to the piece to be cut or to the metallic
workbench. Take following precautions:
√ Verify that there is a good electrical contact particularly if insulated or oxidated coated sheets
are cut.
√ Make ground connections as close as possible to the cutting area. The use of the metallic struc-
tures which are not part of the workpiece, such as the return cable of the cutting current, may
endanger the safety system and give poor cutting results.
√ Do not make a ground connection on the piece which has to be removed.
TORCH CONNECTION
WARNING!: Before starting the cutting operations verify that the parts are properly assembled
by inspecting the head of the torch as shown on paragraph "Torch Maintenance"
LOCATION AND HANDLING OF THE POWER SOURCE
√ Choose location verifying that there is a good air fl ow and no dust, smoke or gas is present.
√ Make sure that obstacles do not prevent the cooling air fl ow out of front and rear openings of
the machine.
√ Arrange an open space of at least 5m around the machine.
√ In the case the machine has to be moved, always disconnect the plug from the outlet and gather
the cables and pipes so as not to damage them.
COMPRESSED AIR
A source of clean, dry air or nitrogen must be supplied to your plasma cutting unit. The supply pres-
sure must be between 72.5 and 150 psi (5 and10.3 bar). The fl ow rate is approximately 3.5 cu.ft./
min. (100L/min.). Failure to observe these precautions could result in excessive operating tempera-
tures or damage to the torch.
An air regulator is included with the unit with optimum pressure setting set to 65 PSI, 4.5 Bar.
Note: the regulator should never be set above 6 bar.
AUTOMATIC PURGE
Oil in the air is a severe problem and must be avoided.
The unit is also equipped with an air fi lter which captures water and oil vapor. The vapor collected
will be automatically drained out through the drain knob located on the bottom of the unit.
Note: The unit will not operate if the input air pressure is below 55 PSI, 3.8 Bar.
