Hello; I just joined this site. I have a tech problem with my Ranger. Its been loosing welding current. I had to keep turning up the dial for the same current setting. Now I can't even stike an arc. I opened up the machine and took some voltage readings. I get 90vdc at the rectifier output and input to the chopper. But only 19vdc at the chopper output and the welder cable lugs. I assume its suppose to be 28vdc at full current? And the voltage should vary with the current control pot? It remains at 19vdc and does not vary. This machine only has 45 hours on it. I paid $3500 new for it back in 2001. I have seldom welded with it (maybe 25 hours of welding) and was mainly used for emergency standby power on my home. The aux 240vac side works just fine. So I am thinking maybe the welding control board went dead or the chopper board is the problem? Any ideas? Does anyone know how much the parts will cost? I am very disapointed with Lincoln.
