Part 6 Daily maintenance and checking
Daily maintenance
a) Remove dust regularly with dry compressed air. If the welding machine is used in surroundings with heavy
smoke and polluted air, it is necessary to remove dust at least one time one month.
b) Examine inside electric joints and ensure perfect contact (Especially plugs and sockets). Fasten the loosing
joints. In case of oxidation, remove oxide film with sand paper and connect again.
c) Prevent water from entering into the machine and prevent the machine from getting moist. If any, blow and
dry. Measure the insulation with megohmmeter to make sure it is qualified to use.
d) If the welding machine is not used for a long time, pack the machine in original package and store in dry
surroundings.
e) Every time the wire feeder operates for 300hours, grind the electrical carbon brush and clear up the
armature commutator. Rinse speed reducer, apply 2# Molybdenum Disulfide lubricant to the turbine,
whirlpool rod and bearing.
All the maintenance and testing must be carried out when the power supply is totally cut off. Please
make sure the power is off before opening the closure.
