function. Some panels vary slightly.
1. Air regulator/filter/water trap. To adjust
air pressure, pull up slightly on the control
knob on the top of the regulator until a click is
heard. Twist clockwise to increase pressure
or counter clockwise to decrease pressure.
Note: Do not exceed 80 psi. When installing
observe directional arrow for air flow. A step
down regulator at the tank is highly recom-
mended as well as an additional air dryer at
the tank. A tank side air filter/dryer will in-
crease consumable life and help keep mois-
ture out of air lines. On the PowerPro series,
be sure to install air pressure gauge in the
middle plug on the regulator housing.
2. Gas Inlet. This port is a dual purpose port
to provide the unit with either Argon or com-
pressed air. As configured in the picture, it
is set up for compressed air. To use Argon,
you must remove air line (5) from port (2)
and install the line from the argon regulator.
Alternately, you may install a T-fitting with
two shut off valves at the inlet to eliminate the

need to change out the plumbing when
switching functions. Do not attempt to oper-
ate the plasma cutter with argon connected
and do not operate TIG with air pressure con-
nected unless a suitable shut-off mechanism
is in place and the lines have been sufficiently
purged. Also, quick disconnect fittings may
be used, but care must be taken not to intro-
duce moisture to the system that collects on
the couplings during change out.
3. High Frequency Ground. This unit pro-
vides a separate grounding point for the high
frequency to help control interference that
high frequency may cause. This ground must
be connected to a separate wire that is
grounded to a metal rod driven into the
ground. It is strongly recommended that you
connect this to a separate ground as pre-
scribed. This will assist in draining the HF
and help prevent interference with electronic
products. Do not ground to cart, table or
ground to the ground wire in the power sup-
ply circuit. Ground only to separate ground
rod. Do not ground back to panel box! When
operating with a generator the above ground-
ing methods must be followed to ensure safe
and correct operation of the unit.
4. Specifications and Serial number. These
specifications override any other published
specifications, as changes may occur from
time to time. Register your unit's serial num-
ber online and record it here in the manual.
5. Switch. Flip switch up to turn the unit on.
If the switch needs to be reset, due to over
current or overheating, flip the switch fully
down then back up to resume normal opera-
tion.
6. Fan Area. Keep area from being blocked.
.Air flow must be free and unobstructed. Al-
low 12 inches of clearance behind fan area.
7. Power cord. The power cord must not be
placed in a strain or the unit pulled by the
cord at any time. To wire, use a standard
NEMA 6-50 P male plug. Most plugs have
wire color coding included in the instruction
manual or printed on the plug itself. Howev-
er, the white is typically wired to the smaller
blade and the black wire to the larger flat
blade. The green wire is for ground only
(middle post). Other types of plugs may be
used, but it is suggested to use the 6-50 se-
ries plugs as it meets most codes.
