Firepower Regulator - Firepower MST 180i Operating Manual

Firepower MST 180i
5. Earthing of the Workpiece
Where the workpiece is not bonded to earth for
electrical safety, nor connected to earth because
of it's size and position, e.g. ship's hull or building
steelwork, a connection bonding the workpiece
to earth may reduce emissions in some, but not
all instances. Care should be taken to prevent the
earthing of the workpiece increasing the risk of injury
to users, or damage to other electrical equipment.
Where necessary, the connection of the workpiece
to earth should 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 regulations.
6. Screening and Shielding
Selective screening and shielding of other cables
and equipment in the surrounding area may alleviate
problems of interference. Screening the entire
welding installation may be considered for special
applications.
INSTALLATION, OPERATION AND SETUP

3.06 Firepower Regulator

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

Use the regulator for the gas and pressure for
which it is designed. NEVER alter a regulator for
use with any other gas.
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
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
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 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, "In-
dicating Pressure Gauges for Compressed Gas
Service."
b) Low pressure gauges must be UL recognized
for the class of regulator they are being used on
according to UL252A.
