Disconnect input plug or power before maintenance or repair on

machine.

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.

The compressed air should be reduced to the required pressure lest

the little parts in the welding machine be damaged.

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.
