9. Set the “Process Selection Switch” to LIFT TIG
10. Set the weld current control knob to the desired
amperage.
11. The tungsten must be ground to a blunt point in order
to achieve optimum welding results. It is critical
to grind the tungsten electrode in the direction the
grinding wheel is turning.
12. Install the tungsten with approximately 1/8” to ¼”
sticking out from the gas cup, ensuring you have
correct sized collet.
13. Tighten the back cap then open the valve on the
torch.
14. You are now ready to begin TIG Welding.
3.08 Firepower Flowmeter/Regulator
Pressure Flowmeter/Regulator (Figure 3-4) attached
to the cylinder valve reduce high cylinder pressures to
suitable low working pressures for welding, cutting, and
other applications.

WARNING
Use the Flowmeter/Regulator for the gas and
pressure for which it is designed. NEVER
alter a Flowmeter/Regulator for use with any
other gas.
NOTE
Flowmeter/Regulators purchased with open
1/8”, 1/4”, 3/8”, or 1/2” NPT ports must be
assembled to their intended system.
1. Note the maximum inlet pressure stamped on
the Flowmeter/Regulator. DO NOT attach the
Flowmeter/Regulator to a system that has a
higher pressure than the maximum rated pressure
stamped on the Flowmeter/Regulator.
2. The Flowmeter/Regulator body will be stamped
“IN” or “HP” at the inlet port. Attach the inlet port
to the system supply pressure connection.
3. Wrap pipe threads with Teflon tape 1 1/2 to 2
turns to effect a seal. If other sealants are used,
they must be compatible with the gas that will be
used in the system.
4. If gauges are to be attached to the Flowmeter/
Regulator and the Flowmeter/Regulator is
stamped and listed by a third party (i.e. “UL” or
“ETL”). The following requirements must be met:
a) Inlet gauges over 1000 PSIG (6.87 mPa) shall
conform with the requirements of UL 404,
“Indicating Pressure Gauges for Compressed
Gas Service.”
b) Low pressure gauges must be UL recognized
for the class of Flowmeter/Regulator they are
being used on according to UL252A.
!
WARNING
DO NOT use a Flowmeter/Regulator that
delivers pressure exceeding the pressure
rating of the downstream equipment unless
pro visions are made to prevent over-
pressurization (i.e. system relief valve). Make
sure the pressure rating of the down stream
equipment is compatible with the maximum
delivery pressure of the Flowmeter/Regulator.
5. Be sure that the Flowmeter/Regulator has the
correct pressure rating and gas service for the
cylinder used.
6. Carefully inspect the Flowmeter/Regulator for
damaged threads, dirt, dust, grease, oil, or other
flammable substances. Remove dust and dirt
with a clean cloth. Be sure the inlet swivel filter is
clean and in place. Attach the Flowmeter/Regulator
(Figure 3-5) to the cylinder valve. Tighten securely
with a wrench.
