10.MAINTENANCE
1. Disconnect input plug or power before maintenance or repair on
machine.
2. Be sure input ground wire is properly connected to a ground
terminal.
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 sandpaper and then re
‐ connect.
4. Keep hands, hair, loose clothing, and tools away from electrical
parts such as fans, wires when the machine is switched on.
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.
6. The compressed air should be reduced to the required pressure
lest the little parts in the welding machine be damaged.
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.
8. If the machine is not used for a long time, put it into the original
packing in dry condition.
