Victor Regulator - ESAB Fabricator 181i Operating Manual

ESAB FABRICATOR 181i
in some countries where direct connection is not
permitted, the bonding should be achieved by suitable
capacitance, selected according to national regula-
tions.
6. Screening and Shielding
Selective screening and shielding of other cables
and equipment in the surrounding area may allevi-
ate problems of interference. Screening the entire
welding installation may be considered for special
applications.

3.06 Victor Regulator

Pressure regulator (Figure 3-1) attached to the cylinder valve
reduce high cylinder pressures to suitable low working pres-
sures for welding, cutting, and other applications.

WARNING
!
Use the regulator for the gas and pres-
sure for which it is designed. NEVER alter
a regulator for use with any other gas.
NOTE!
Regulators purchased with open 1/8",
1/4", 3/8", or 1/2" NPT ports must be as-
sembled to their intended system.
1. Note the maximum inlet pressure stamped on the
regulator. DO NOT attach the regulator to a system
that has a higher pressure than the maximum rated
pressure stamped on the regulator.
2. The regulator body will be stamped "IN" or "HP" at
the inlet port. Attach the inlet port to the system sup-
ply 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 regulator and the
regu lator 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."
INSTALLATION, OPERATION AND SETUP
b) Low pressure gauges must be UL recognized for
the class of regulator they are being used on ac-
cording to UL252A.
WARNING
!
DO NOT use a 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 regulator.
5. Be sure that the regulator has the correct pressure
rating and gas service for the cylinder used.
6. Carefully inspect the 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
regulator (Figure 3-2) to the cylinder valve. Tighten
securely with a wrench.
WARNING
!
DO NOT attach or use the regulator if oil,
grease, flamma ble substances or dam-
age is present! Have a qualified repair
technician clean the regulator or repair
any damage.

7. Before opening the cylinder valve, turn the regulator
adjusting screw counterclockwise until there is no
pressure on the adjusting spring and the screw turns
freely.
8. Relief Valve (where provided): The relief valve is
designed to protect the low pressure side of the
regulator from high pres sures. Relief valves are not
intended to protect down stream equipment from high
pressures.
