7. MAINTENANCE.
WARNING: The following operation requires sufficient professional knowledge on electric
aspect and comprehensive safety knowledge. Operators should be holders of valid
qualification certificates(still in validation) which can prove their skills and knowledge. Make
sure the input cable of the machine is disconnected from the electricity utility before
uncovering the welding machine.
1) Check periodically whether inner circuit connection is in good condition (esp. plugs). Tighten the loose
connection. If there is oxidization, remove it with sandpaper and then reconnect.
2) Keep hands, hair and tools away from the moving parts such as the fan to avoid personal injury or machine
damage.
3) Clean the dust periodically with dry and clean compressed air. If welding environment with heavy smoke and
pollution, the machine should be cleaned daily. The pressure of compressed air should be at a proper level in
order to avoid the small parts inside the machine being damaged.
4) Avoid rain, water and vapor infiltrating the machine. If there is, dry it and check the insulation of the equipment
(including that between the connections and that between the connection and the enclosure). Only when there
are no abnormal phenomena anymore, the machine can be used.
5) Check periodically whether the insulation cover of all cables is in good condition. If there is any dilapidation,
rewrap it or replace it.
6) Replace the contact tip and drive roll timely. Clean the wire feeding tube periodically.
7) Check periodically whether the gas hose is in good condition. If there are any cracks, replace it.
8) Put the machine into the original packing in dry location if it is not used for long time.
