5 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) The pressure of compressed air shall fall to required level to prevent damage to small
components in the machine.
c) 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.
d) 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.
e) If the welding machine is not used for a long time, pack the machine in original package and
store in dry surroundings.
f) 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.
