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.
