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.
As a general rule the power supply should be inspected at least annually.
Consult your CLARKE dealer for advice if necessary.
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 (Part number: 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.
