ASSEMBLY & INSTALLATION

D. Gas Supply

It is necessary to procure a cylinder of gas, suitable for the job in hand.

Locate the gas cylinder on the platform at the rear of the unit, and secure using

the chain provided.

A regulator is provided, complete with outlet pressure gauge for use with argon or

argon mix gas bottles. Should you require to use Carbon Dioxide, it will be necessary

for you to purchase an appropriate regulator with a female connector. Your Clarke

dealer will be happy to advise in this regard.

Ensure the outlet of the gas bottle is clean, then screw on the regulator and nip

up... do not overtighten.

Always use the appropriate gas for the material being welded. If you are unsure,

consult a qualified tradesman, or a suitable reference book.

Attach the nut and tail to the gas hose, using the worm drive clip provided, then

screw the nut on to the regulator outlet and tighten.

Open the gas valve and screw in the regulator knob allow gas into the system to

check for gas leaks. If any are apparent, they must be rectified before proceeding.

Turn off the gas when satisfied the system is leak free.

C. Hose & Earth Cable

Simply screw the Torch Hose connector into the adapter on the front panel (see Fig

4.), taking care to ensure the pins are correctly aligned. DO NOT force it into place.

Tighten the large plastic round nut.

The earth cable plug is inserted into its receptacle on the lower front panel, ensuring

the key lines up with the keyway, and then rotated through 90 degrees to lock

into place.

MAINTENANCE

WARNING!

ELECTRICITY CAN KILL....NEVER TOUCH LIVE ELECTRICAL COMPONENTS

DISCONNECT THE POWER SUPPLY BEFORE ALL INSPECTIONS AND

MAINTENANCE OPERATIONS

BEWARE HOT SURFACES.....ALWAYS LET THE POWER SUPPLY COOL DOWN

BEFORE ACCESSING INTERNAL COMPONENTS.

Frequency of maintenance operations depends on the operating conditions, how

intensively the welder is used, and how clean or dirty the welding site is (aggressive

atmospheres, etc.).

Always inspect the earth return and torch hose, before use to ensure they are in perfect

condition and earth clamp is clean and secured correctly to the cable.

Check the gas hose and Pressure Regulator for security and serviceability, and

ensure there is sufficient gas to complete the job in hand.

As a general rule the power supply should be inspected internally at least annually.

Consult your CLARKE dealer

THE WELDING SHIELD

Always maintain the welding mask in good condition. If the clear glass protection lens

becomes badly pitted, sufficient to interfere with vision, or cracked, have it replaced

immediately. Replacement clear and dark lenses are available from your Clarke dealer

- see Parts Lists for details. NEVER use any dark filter lens other than that provided by

CLARKE International, or one with the same certified ‘Optical class’ (degree of protection).

The shield should always be cleaned with a clean soft cloth after use, ensuring the lenses

are clean. Remove any dust that may have accumulated and store it in a safe place

where it cannot be damaged. NEVER use a shield that is not in perfect condition.

If the liner becomes damaged or kinked, it will be

necessary to replace it.

1. Remove the welding wire from the hose and

torch assembly, either by cutting it at the wire

spool and pulling through from the nozzle end,

or rewinding it back on to the spool.

2. Disconnect the hose from the machine.

3. Unscrew the end nut shown in Fig. 11 using

RENEWING THE WIRE LINER

a 12mm spanner, and, having

straightened the hose assembly, pull

the liner completely out of the hose.

4. Thread the new liner into the hose fully, then

screw the end nut back into place.
