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
atmospheres, etc).
Always inspect the cables, both earth and torch cable, before use to ensure they
are in perfect condition.
Ensure the earth clamp is clean and secured correctly to the cable.
Check the hose for security and serviceability.
As a general rule the covers should br removed and the transformer, and other
components, should be inspected at least annually. Consult your CLARKE dealer
for advice if necessary.
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.
WELDING TIPS
1.
Try to maintain the tip of the nozzle at an angle of approx. 45
O
and at a constant
distance of approx 5-7mm from the workpiece.
2.
Try to maintain a constant speed of movement with the torch.
3.
Do not weld in windy conditions or in an area where ventilation is a problem,
or where air flow fluctuates.
4.
ALWAYS keep the wire and nozzle clean...NEVER use rusted wire.
5.
Avoid sharp bends or kinks in the welding hose.
6.
Whenever possible, clean out the wire liner with compressed air when
replacing the wire spool.
7.
Periodically remove the dust, using LOW PRESSURE compressed air, within the
casing. Adequate heat dissipation is essential during the welders operation.
