Check the connection of input and output cables and the earth (ground) connection, etc.
Maintenance should be conducted by the trained personnel.
The newly installed machine or the welder not in use for some time needs to be checked by

multimeter have the right insulation resistance between each winding and the case.

When the welder is used outdoors, it should be kept from rain or long exposure to the sun.
Check is needed from time to time to make sure the welding cable is in good condition if the

welding machine is in frequent use. Check at least once each month if the welder is in
regular use. It is necessary to check when the welder is in mobile use.

If the welder is not in use either for a long time or temporarily, it should be kept dry and have

good ventilation to free it from moisture, erodible or toxic gas.

Dust removal is needed every year. Check the machine's fasteners, moving-iron, current

regulation screws, etc to make sure there are no loose connection problems.

The dust, acid and erodible dirt in the air at the job site can not exceed the amount required

by the norm (excluding the emission from the welder).

The welder must be installed in the place where it can not be exposed to sun and rain. Also it

must be stored in less humid place with the temperature.

When the machine is operating, the temperature must not be higher than 40 C or lower

than 10 C.

There should be 50 cm space about for the welding machine to have good ventilation.
Make sure that there is no metal-like foreign body to enter the welding machine.
Electrode must be taken down from holder when no welding.
No violent vibration in the welder's surrounding area.
Make sure that there is no interference with the surrounding area at the installation site.

Each item listed below must be carefully checked before operation:

Make sure that there is no short circuit connection with welder's both outputs.

Make sure that there is always sound output and input wire connection instead of exposing it
outside.

Regular check needs to be conducted by the qualified personnel after the welding machine has

been installed over a long period or re-operation, which involves as follows:

Check the welding cable to see if it can continue to be used before it is worn out.
Replace the welder's input cable as soon as it is found to be broken or damaged.

Make sure whether there is enough power supply to make the welding machine work properly.

Any power source required to access the welding machine must be installed with some
protective equipments.

Please do not hesitate to contact us for technical assistance whenever you come across the
problems you can not work out or you may deem difficult to fix.
