FUNCTION

This pressure regulator is ideal for use with most TIG welding machines, in particular, the CLARKE AT welder range.

The function of the pressure regulator is to reduce and stabilise the pressure of a gas supply stored in the cylinder. It is used to reduce the pressure to a level which is suitable for use with standard welding equipment.

The pressure regulator has been designed to be used exclusively with the type of gas, and at the pressure indicated in the Technical Specification on page 7.

IMPORTANT: To use the pressure regulator with types of gasses and pressures other than CO2 or Argon could be dangerous.

GENERAL SAFETY PRECAUTIONS

IMPORTANT! In addition to the following precautions, you should read, and fully comply with, all instructions and safety precautions that were supplied with your Welder. Please keep these instructions in a safe place for future reference.

1. Incorrect use of the pressure regulator can cause serious damage or injury.

2. Always check that the regulator is the correct model for the type of gas being used.

3. This pressure regulator must be treated as a precision instrument and be protected from impact, dust, oil and dirt.

4. Never use the pressure regulator if it is not in perfect working order.

5. When drawing gas from the cylinder, it must always be stood upright and be protected from falling.

6. Always ensure that any inlet connection gasket is in place and in good condition.

ASSEMBLY

CONNECTION OF THE PRESSURE REGULATOR

Note; The numbers in brackets refer to the parts diagram on page 6.

1. Check to ensure the pressure regulator is correct both for the type of gas and the pressure in the cylinder to be used.

2. Turn the pressure adjuster (4) fully anti-clockwise, (towards the - mark) to ensure the pressure adjuster valve is closed.

3. Before screwing on the pressure regulator, ensure that the outlet is absolutely free from any impurities or contamination.

4. Replace any gasket if damaged or lost (CO2 applications ONLY).

5. Screw the inlet connection (2) tightly to the cylinder valve, using a suitable spanner.

HOSE CONNECTION 1. Attach the hose to the hose outlet connection (5) and tighten with

suitable worm drive clamps (not provided), ensuring the connection is tight.

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.

MAINTENANCE

Do not attempt to carry out maintenance or repairs yourself.

Do not dismantle the regulator. Return it to your Clarke dealer for servicing.

Do not clean gauge lens with solvents/petrol etc.

MALFUNCTIONS Do not use the pressure regulator if:

The pressure regulator or any of its parts (gauge, inlet connection, outlet connection) are damaged or dirty, oily etc.

There are any leaky connections.

The pressure relief valve has been tampered with, or is leaking.

If the gauge malfunctions during use, (e.g. leaks) stop work immediately and close the cylinder valve.

Return the regulator to your dealer to be checked and repaired.

CHECKING FOR LEAKS Checking for leaks must be carried out only in the open air. Use soapy water as a gas leak detector. Do not use a flame.

Spray a suitable leak detector or apply soapy water onto the area to be checked.

The forming of any bubbles or foam is an indication of a leak.

STORAGE The pressure regulator must be treated as a precision instrument. When it is not to be used for long periods, store it in its packaging or in its box to prevent contact with dust, oil and other sources of contamination.
