Hey, y'all. Wasn't sure where to post this, but I was hoping someone here has some experience with welder/generators.
I'm working on a Lincoln Ranger 9 Welder that is putting out low voltage, like 70 VAC. I know the problem isn't the engine, or the governor settings, but on the generator side of things. It has been sitting a lot, so I thought that maybe the capacitors needed to be flashed (flashing the exciter field). I used two methods. First, i unhooked the leads from the capacitor bank, and flashed the capacitors with AC house current. The capacitors are rated at 50 volts, so I decided to flash the whole bank as a unit so as not to overload anything. I hooked everything back up, and started it up. Thought I fixed it for a brief second, got 117 volts, but it immediately started slowly dropping back down to 70. Tried another method, where with the engine off, I plug in a typical drill, and while holding the drill's power switch, I hand crank the drill in reverse for a little bit (like 15 - 20 seconds), and then start the welder up. That too had limited success, started out around 96, and once again dropped to 70.
Did any of that make sense to anyone here? Does it sound like a typical problem? I'm thinking maybe a bad capacitor or two, if not, it could be circuit board or regulator. Any thoughts?
