INSTALLATION
A. Unpacking
Unpack all items and verify that all items
have been received according to the
packing list enclosed.
B. Operating Environment
Make sure working area is well
ventilated.
The unit is cooled by an axial-
flow fan which provides airflow through the
back panel over the electronics and out the
machine cover vents.
(NOTE! The cover
must be installed with the vents closest to
the front of the machine)
Provide at least 6
inches in the rear and 6 inches on each side
for clearance. If unit is operated without
sufficient cooling the duty cycle will be
greatly reduced.
C. Input Cable Connection
Every machine includes a primary input
power cable capable of handling the input
voltage and current for this unit. If the unit is
connected to power that exceeds the
required voltage, or is of the incorrect phase,
serious damage will be incurred and
warranty will become void.
This machine may operate on either 220 or
110/220 volts single phase 50/60hz
depending upon which version you have.
Proper input voltage can be determined by
observing the labels next to the power cord
strain relief and will be labeled 220 V or
110/220 volts for the dual-voltage machines.
Service must be fused for at least 40mps.
Neutral (Ground) wire is yellow with a green
stripe or solid green. This wire must be
connected to the “ground” terminal of the
power plug you use.
If using an extension cord, make sure that it
meets
or
exceeds
the
following
recommendations:
For 220 VAC Service Up to 50 ft. 14 AWG
Up to 100 ft 12 AWG
Note
: The input current required to produce the
same output power is inversely proportional to
the input voltage. Example: If the machine draws
22 amps @ 220 volts it will draw 44 amps @ 110
volts to produce the same power output. This is a
law of electronics theory… Power = Volts * Amps
D. Torch Connection
Connect the Torch to the inverter by
screwing the air line fitting on the end of
the torch to the torch connector fitting on
the front of the machine.
Secure by tightening with wrench slightly.
DO NOT OVER TIGHTEN!
TORCH ASSEMBLY
A. Torch Assembly Procedure
Position the torch with the shield cup
facing upward and unscrew and remove
the shield cup from the torch head
assembly (The shield cup holds the tip,
ceramic swirl ring, and electrode in place).
Remove the tip, ceramic swirl ring, and
electrode.
Install the electrode, ceramic swirl ring, and
tip. Replace worn parts, as necessary.
Install and hand tighten the shield cup until it
is seated on the torch head. If resistance is
felt when installing the cup, check the
threads and parts configuration before
proceeding.
Note:
On some torches that do not have reversible
electrodes it will be necessary to secure the
electrode by slightly tightening with pliers to
assure reliable electrical connection.
OPERATION
A. To Begin
Turn the Power Switch to the ON position.
