MAINTENANCE

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 environments etc).

Always 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.

Check the hose for security and damage.

Wire feed unit

The feed roller wire guide plays an important part in obtaining consistent

results. Clean the rollers weekly, especially the feed roller groove, removing all

dust deposits.

Torch

Protect the torch hose assembly from mechanical wear. Clean the liner from

the machine forwards by using compressed air. If the liner is blocked 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.

WARNING: ELECTRICITY CAN KILL - NEVER TOUCH LIVE ELECTRICAL

COMPONENTS.

WARNING: DISCONNECT THE POWER SUPPLY BEFORE ALL INSPECTIONS

AND MAINTENANCE OPERATIONS. BEWARE HOT SURFACES.

WARNING: ALWAYS LET THE WELDER COOL DOWN BEFORE ACCESSING

INTERNAL COMPONENTS.
