In order to keep that the welder and generator set is in a good state, the regular inspection
and maintenance is very important. The set is composed of the diesel engine, welder generator,
control cabinet, frame and so on. For the details about the inspection and maintenance, please
read the operation and maintenance manual for each assembling section.
Before carrying out the maintenance to the set, please turn off the diesel engine. If it is

corrosion and remove the sink materials.
