Setup Guide
Getting Started
Connecting Argon shielding gas for versus
connecting compressed air.
This unit is equipped with only one inlet in the rear for gas supply.
This means that both shielding gas for TIG welding and the Air sup-
ply for plasma cutting uses the same fitting.
With that said here are some things to keep in mind.
1) Never, under any circumstance run the shielding gas through
the air regulator. Gas flow will be inconsistent and difficult to
regulate.
2) As equipped, you will need to disconnect the air regulator at the
bottom rear inlet on the unit and reconnect the shielding gas
cylinder fitting to the bottom inlet and vice versa when you
change between processes.
3) Since the connection TIG connection and Air Compressor con-
nection is shared at the bottom rear of the unit, and the same
solenoid and tubing govern the delivery of both gases to the
torches, special care should be exercised to keep the compres-
sor air dry. Any residual moisture in the lines while welding TIG
can create contamination problems. This is also true for oil
from worn compressors getting into the line. Make sure that
Air compressors and dryers are drained or serviced regularly to
eliminate the possibility of contaminating the lines with both oil
and water.
4) Install a separate air dryer before the air reaches the regulator
on the unit. It is best to place it 2 or 3 feet away and use a
short jumper hose between the air dryer and the regulator. If
this cannot be done, then install a dryer directly at the compres-
sor.
5) Use a dedicated air hose intended for use only while plasma
cutting. This will reduce the change of cross contamination
when automatic tool oilers are used in the system.
6) You may install a Y valve, or a ball valve and T fitting at the rear
of the unit if you do not want to switch fittings back and forth
when changing processes. If a valve is desired to switch gases
more quickly, consider using an inert gas Y valve, such as a
Western #411 or similar model valve.
7) The pressure gauge on the front of the welder may register-
some pressure while in TIG welding mode with the shielding
gas connected. The presence of, the absence of, or the amount
of pressure registered is not relevant or of concern while TIG
welding. Use only the flow meter included with this unit to
measure and regulate the actual shielding gas flow rate. The
pressure gauge on the regulator only registers cylinder pres-
sure and is used to determine a relative amount of cylinder
contents remaining.
