Maintenance of the Welder and Generator Set

4.1  Regular Maintenance

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 maintenance to the set, please turn off the diesel engine. If it is 
necessary to run the diesel engine, its surrounding should be in good ventilation to 
discharge the gas that contains the poison carbon monoxide.
After using the set, it is necessary to wipe off dirt by using a clean cloth to prevent 
the corrosion and remove the sunk materials.

3.9. KDE180 SET

3.9.1 The updated AVR technology and IGBT module control technology are 

applied in KDE180 generators, which ensures stable welding current and 

generating voltage. And there won't be any interference between the generating 

and generating voltage. And there won't be any interference between the 

generating and welding condition when they are used simultaneously. The unit 

can be applied for welding and generating simultaneously, however, the total load 

of the unit cannot surpass the rated load.

The welding current data table:

3.9.2 Choose the welding current with selection button and a regulating knob 

according to the width of work piece and the diameter of the welding rod. When 

the small current for thin steel piece is required, first turn the regulating knob to

 

LOW

, and then choose the appropriate small current by regulating the regulation 

knob. The regulation range for this work condition is 50-140A. When big current 

for thick steel pieces is required, turn the regulating knob to 

HIGH

. Then you can 

choose a big current by regulating the regulating knob. Then regulation rage for 

this work condition is 80-180A.
