Operating Instructions 

 

 
 
 

This welder is a hydraulically driven welder and it is extremely important that 
the hydraulic system can supply the proper flow and pressure to maintain a 
welder speed of 3,600 RPM under load.  If the welder drops below 3600 RPM, 
it cannot perform properly. 

 

 

‰ 

Start Hydraulic system 

 

‰ 

Turn welder hydraulic system on 

 

‰ 

Allow welder 2-3 minutes for warm-up 

 

‰ 

Be sure the red light between the 2 AC receptacles is lit 

 

‰ 

This will show you that the welder is close to the proper RPM and that 

you have AC generator output 

 

‰ 

Insert welding leads into welding receptacles 

 

 

CAUTION 

– Be sure that the positive cable is in the positive receptacle and 

the negative cable in the negative receptive. 

 

 

Set Range Selector switch to the position that is in the amperage range you 
need for your welding job.  Then set the Amp Selector switch to the amperage 
that is nearest your desired amperage.  Begin to weld.  You may have to 
switch one position up or down to get the desired amperage. 

 

 

NEVER  MOVE  ANY SWITCHES DURING  WELDING
