9 Routine 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 megaohmmeter 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 300 hours, 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.
