Installation
3.08 Using a Shielding Gas for
(GMAW) Process
NOTE:
Shielding Gas is not required if the unit is
used with self shielded FCAW (flux cored
arc welding) wires.
Cylinder positioning
Chain the gas cylinder to a wall or other support to
prevent the cylinder from falling over. If an optional
portable mounting is used, follow the instructions
provided with it. Remove the cap from the cylinder.
Regulators – fitting to cylinders
Screw the regulator into the appropriate cylinder as
shown in Figure 3-4. The nuts on the regulator and
hose connections are right hand (RH) threaded and
need to be turned in a clockwise direction in order to
tighten. Tighten with a spanner.
CAUTION
Match regulator to cylinder. NEVER
CONNECT a regulator designed for a
particular gas or gases to a cylinder
containing any other gas.

Figure 3-3: Fit Regulator to Cylinder
Regulators – fitting to welder.
Blow out the hose before connecting to the regulator
and rear of welding power source – to remove dust,
talc, etc. The nut on the hose connection is right hand
(RH) threaded and needs to be turned in a clockwise
direction in order to tighten.
Adjusting Regulator
Adjust the control knob on the regulator to the required
flow rate, indicated on the gauge dial (approximately
10 - 15 LPM). Refer to Figure 3-5.
NOTE:
All valves downstream of the regulator
must he opened to obtain a true flow rate
reading on the outlet gauge. The welding
power source must also be triggered.
Close the valves after the pressure has
been set.
Art: A-05088_AB
Figure 3-4: Adjust Flow Rate
A slight readjustment to the setting may be required
when equipment is in operation. Refer to the Welding
Setting Selection Guide in section 4.
!
WARNING
Only use the correct inert shielding gas
as recomended by the Mig welding wire
or shielding gas manufacturer.
