2.4 START-UP
Only qualified persons are to install, operate or ser-
vice this unit according to all applicable codes and
safety pratices.

2.4.1 INSTALLATION

Position the plasma machine so you do not to limit the
cooling.
Do not place the plasma machine on floor with inclination
greater than 10°.
Make sure that the supply voltage is 120V 50/60Hz
and a minimum of 20 amp service. If connected to a cir-
cuit protected by fuses, use time delay fuse marked "D".
Connect the air supply to the fitting B.
• If the system air contains a considerable amount of
moisture and oil, it is best to use a drying filter to avoid
excessive oxidation and wear of the consumer parts, dam-
aging the torch and reducing the cutting speed and quality.

• If the air supply comes from a pressure regulator of a
compressor or centralized system, the regulator must be
set to an output pressure of no more than 116 P.S.I.
• If the air supply comes from a compressed air cylinder,
the cylinder must be equipped with a pressure regula-
tor. Never connect a compressed air cylinder directly
to the regulator on the machine! The pressure could
exceed the capacity of the regulator, which might ex-
plode!
Connect the power cord A: the plug must be connected
to an efficient grounding socket on the system.
The capacity of the cut-out switch or fuses installed in
series with the switch must be equal to the current I1 ab-
sorbed by the machine.
The absorbed current I1 may be determined by reading
the technical specifications shown on the machine under
the available supply voltage U1.
Any extension cords must be sized appropriately for the
absorbed current I1.

3 USE

Make sure the trigger has not been pressed.
Turn the machine on using the switch C. The warning
lamp D will light to indicate that the machine is on.
Press the torch button to start the pilot arc.
Now adjust the pressure, shown on the pressure gauge F,
to 50 P.S.I , using the knob E on the regulator, then lock
the knob by pressing it downward.
Connect the ground clamp to the workpiece.
The cutting circuit must not be deliberately placed in di-
rect or indirect contact with the protective wire except in
the workpiece.
Fig.2
are in good electrical contact, especially with painted
or oxidized metal or with insulated coating; Connect the
clamp as close as possible to the cutting area.
Do not connect the grounding clamp to the part of the
material that is to be removed.
Press the torch trigger to strike the pilot arc.
If cutting does not begin within 2 seconds, the pilot arc
goes out; press the trigger again to re-strike it.
Begin cutting.
Hold the torch upright while cutting.
When you have finished cutting and released the trigger,
air will continue to leave the torch for approximately 30
If the workpiece is deliber-
ately grounded using the
protective conductor, the
connection must be as di-
rect as possible and use
a wire of at least the same
size as the cutting current
return wire. Every precau-
tion must be taken to avoid
stray currents. Use the knob
M to adjust the cutting cur-
rent from 5 to 20 A based on
the work at hand.
Make sure that the ground
clamp and the workpiece
