CARE AND MAINTENANCE

The machine requires no maintenance other than the following guidelines. Cleaning

at frequent intervals is advisable if the unit is operating in a very dusty environment.

Avoid getting particles of metal inside the machine since they could cause short

circuits and be alert to any unusual noises or smells.

1. Keep the louvres clean to avoid a build up of dirt inside the machine which can

reduce machine output or become a hazard.

2. Check all cables periodically for good condition and security.

3. Inspect the earth cable and torch hose before use, to ensure they are in perfect

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

4. Check the hose for security and damage.

Wire feed unit:

The feed roller / wire guide plays an important part in achieving consistent results.

Periodically check the contact surfaces including the feed roller groove, removing any

deposits. and checking the smoothness of rotation. Note that poor wire feeding can

cause the welding arc to be unstable.

Check that the centre of the feed tube and the centre of the wire feed wheel groove

line up exactly.

Torch:

Protect the torch hose assembly from mechanical wear. If the liner is blocked or

damaged it must be replaced.

Contact tip:

The contact tip is a consumable item and must be replaced when the bore becomes

enlarged or oval. The contact tip must be kept free from spatter to ensure an

unimpeded flow of gas.

To keep the contact tip free from spatter, we recommend the use of anti-spatter spray

(6000715) available from your CLARKE dealer.

Torch shroud:

The torch shroud must also be kept clean and free from spatter. Build-up of spatter

inside the gas cup can cause a short circuit at the contact tip which will result in

expensive machine repairs.
