Victor Flowmeter/ Regulator - ESAB fabricator 141i Operating Manual

ESAB FABRICATOR 141i
be made by direct connection to the workpiece, but
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 Flowmeter/ Regulator

Flowmeter/ Regulator (Figure 3-1) attached to the cylinder
valve reduces 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!
Flowmeters/ Regulators supplied with
5/8" -18 standard inert gas connections.
Flowmeters/ 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 flowme-
ter/ 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/ regula-
tor 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
INSTALLATION, OPERATION AND SETUP
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 pres-
sure 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 dam-
aged threads, dirt, dust, grease, oil, or other flam-
mable 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 3-2) to
the cylinder valve. Tighten securely with a wrench.
WARNING
!
DO NOT attach or use the flowmeter/
regulator if oil, grease, flamma ble sub-
stances or damage is present! Have a
qualified repair technician clean the flow-
meter/ 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.
7. Relief Valve (where provided): The relief valve is
designed to protect the low pressure side of the flow-
meter/ regulator from high pres sures. Relief valves
are not intended to protect down stream equipment
from high pressures.
