FIREPOWER TIG 200 AC/DC INSTALLATION

Installation
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. 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.
4. Be sure that the Flowmeter/Regulator has the correct pressure rating and gas service for the cylinder used.
5. 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 3-9) to the cylinder valve. Tighten securely with a wrench.
!
WARNING
DO NOT attach or use the Flowmeter/Regulator if oil, grease, flamma ble substances or damage is
present! Have a qualified repair technician clean the Flowmeter/Regulator or repair any damage.

6. Before opening the cylinder valve, turn the Flowmeter/Regulator adjusting screw counterclockwise until
there is no pressure on the adjusting spring and the screw turns freely.
