INSTRUCTIONS FOR USE

OPENING THE PRESSURE VALVE

1. Check to ensure the regulator is completely closed (turn the pressure

adjuster knob (4) fully anticlockwise).

WARNING: OPENING THE CYLINDER VALVE TOO QUICKLY MAY CAUSE

THE GAUGE TO MALFUNCTION.

2.

Turn the pressure adjuster (4) very slowly clockwise. The pressure gauge

(3) will indicate the outlet pressure.

3. To increase pressure, slowly turn the pressure adjuster (4) clockwise until

the reading on the gauge is at the pressure you require.

4. To decrease pressure, slowly turn the pressure adjuster (4) anti-clockwise.

5. As the gas is used up and the pressure drops, compensate by screwing

the pressure adjuster (4) clockwise to maintain the outlet pressure.

6. Outlet pressure must not be adjusted higher than the pressure you need to

use.

SHUTTING DOWN

1. ALWAYS release the pressure from the regulator when not in use, and

remember to turn OFF the gas supply as soon as you have finished

welding.

2. Close the cylinder valve (1).

3. Release the gas pressure, by operating the welding equipment until the

regulator gauge indicates “zero” and no more gas can be heard

exhausting.

4. Turn the pressure adjuster (4) anti-clockwise until it is completely closed.

Note; ALWAYS close the cylinder valve before attempting to change an

empty cylinder.

RELIEF VALVE

For safety reasons, the pressure regulator is equipped with a pressure relief

valve.

In case of malfunction, this valve allows gas delivered at excessive pressure

to escape.

WARNING: DO NOT TAMPER WITH THE PRESSURE RELIEF VALVE.
