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 cables, both earth return and torch cable, 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.
