Additional Safety Precautions - Hobart Welders GMAW Manual

4. Additional Safety Precautions

Use regulator only for Gas Metal Arc Welding (GMAW). Do not
!
use this regulator with gases other than those for which it is in-
tended. Contact the gas supplier and consult the MSDS sheet to
be sure the compressed gas is compatible with regulator com-
ponents. Do not interchange regulators or other equipment un-
less the gases that were used are compatible.
Inspect all equipment before use. Do not use damaged, defect-
!
ive, or improperly adjusted equipment. Make sure levers and
valves work properly, threads on equipment are clean (no grease
or oil) and not deformed, gauges are intact and easy to read, reg-
ulator is clean and free of oil or dirt, and fittings are properly sized
for the cylinder. Make sure hoses are clean (no grease or oil) and
ferrules are properly installed so the fitting does not slip inside
the hose. Be sure all connections are tight.
Check compressed gas system for leaks with an approved leak
!
detection solution or leak detector.
Do not lubricate regulator, gauges, or compressed gas fittings.
!
Stop using the regulator immediately and contact the gas suppli-
er if oil or grease is found in these components. Take regulator
and other components to a qualified repair station for cleaning.
Do not use sealing tape on cylinder connections.
Do not use adapters on cylinder connections. Use a regulator
!
with the correct compressed gas fitting.
Do not open the cylinder valve more than necessary to clear the
!
valve port. Opening the valve too much may cause the cylinder
to tip over due to the force of the escaping gas. Never stand in
front of the valve port.
Do not stand in front of or behind a regulator when opening the
!
cylinder valve.
Do not use regulator as a shut-off device. Close cylinder valve
!
when system is not in use.
