10. MAINTENANCE.
10.1
Disconnect input plug or power before maintenance
or repair on machine.
10.2 Be sure input ground wire is properly connected to a
ground terminal.
10.3 Check whether the inner gas-electricity connection is
well (esp. the plugs), and tighten the loose connection; if
there is oxidization, remove it with sand paper and then
re-connect.
10.4
Keep hands, hair, loose clothing, and tools away from
electrical parts such as fans, wires when the machine is
switched on.
10.5
Clear the dust at regular intervals with clean and dry
compressed air; if the working condition is with heavy
smoke and air pollution, the welding machine should be
cleaned daily.
10.6
The compressed air should be reduced to the
required pressure lest the little parts in the welding
machine be damaged.
10.7
To avoid water and rain, if there is, dry it in time, and
check the insulation with mega-meter (including that
between the connection and that between the case and
the connection). Only when there is no abnormal
phenomenon should the welding continue.
10.8
If the machine is not used for a long time, put it into
the original packing in dry condition.
11. DAILY CHECK.
To make best use of the machine, daily checking is very important. During the daily checking, please check in
the order of torch, wire-feeding vehicle, all kinds of PCB, the gas hole, and so on. Remove the dust or replace
some parts if necessary. To maintain the purity of the machine, please use original welding parts.
