The regulator assembly serves as both a filter/water
trap, and an air regulator. The water trap with the
fine sediment filter is self draining. It is not designed
to dry the air, but rather serves the purpose of
catching any residual slug of water that may be
present in the air line and filtering any trash or
sediment that passes into the bowl of the regulator.
It is not designed to serve as an air dryer. A
separate air dryer must be placed between the
regulator and the air compressor.During the
assembly of the regulator, be sure to screw the 1/4”
automotive quick connect into the side that is
stamped on top with “IN” or that has been stamped
with an arrow pointing to the center of the regulator.
The small brass plug should screw into the center of
the regulator and the remaining push-to-connect
fitting should be screwed into the remaining hole.
Then, connect the clear tubing to the push-to-
connect. Make sure the shoulder of the tubing has
been cut squarely or the connection may leak as a
result. Screw the regulator bracket to the back of
the plasma cutter first before attaching the regulator
to the bracket. Make sure the screws located in the
accessory bag are the proper length and are
inserted with the accompanying lock and flat
washers. To adjust the regulator, simply pull the
knob up slightly until it clicks, and rotate the knob
clockwise to increase the pressure or counter
clockwise to decrease the pressure. To lock in the
setting, push the knob down until it clicks. Do not
exceed 90 psi supply pressure. Do not exceed 85
psi on the plasma cutter side of the regulator or
internal leakage may result. Operating air pressure
should be set between 70 and 75 psi while in to
“Test” mode.

The gas input line is connected to the Regulator
assembly via the clear tubing provided in the
accessory package. To attach, simply push the
tubing into the connector until it is firmly seated then
give a slight tug to make sure it has been captured
correctly by the fitting. Make sure that the tubing
shoulder is squarely cut and not cut at an angle. An
uneven or angular cut will cause leaking at the
connector. If the tubing must be removed, simply
push on the outer plastic collar back while holding
the tubing firmly in the other hand.
