MAITENANCE

WARNING:

All maintenance and checking work should be carded out

under the circumstance of light off .Make sure the power plug is pulled off

before you open the case.

1) Use clear and dry compressed air to remove the dust in certain period, if the

machine is working under heavy-polluted environment, clear it daily.

2) The pressure of the compressed air should be in a suitable level lest it

damages the little parts in the machine.

3) Check the inner circuit connection in the welding machine, and make sure

the connections are right and firm (esp. plug-in or parts) ; if there is rust or

loose, use the sand-paper to rub off the rust or oxidized coating and

re-connect it firmly.

4) Avoid water or water gas into the inner of the machine, if happens, please

first dry it, and then measure the insulation situation with Omen meter.

(Including the joints and joint vs. case) .Do not continues until you make

sure there is no abnormal phenomenon.

5) If the machine is not used for long time, please put it into the original box

and keep it in dry condition.

PRE-CHECKING

WARNING

Blind experiment and incautious checking may cause trouble for formal repair

and make the breakdown area bigger. And the inner bare parts of the machine

have voltage that may cause dangers if it has power supply, so any direct or

indirect touch may cause accidents of electric shock, and heavy shock may

even cause death!

Caution: During the maintenance period, if not authorized, any

personal wrong repair to the welders may cause the maintenance

invalid.
