have a Lincoln 225-S AC welder that is really old, not sure on the year, it was given to me by a friend that has three Arc welders and couldn't remember when he had used this one last (Honest guy so nothing funny going on) Anyway when I cracked the case it looked like it was wired up wrong. This seemed to be confirmed once I turned on the power it blew the main breaker on my 100 amp box. Anyway I'm wondering if you guys can tell me what I'm doing wrong or whether or not this unit is shot.
The directions say For 230 volts Connect H3 & Fan Motor to Switch and insulate Lead H2.
For Low line voltage Connect H2 to Switch and insulate connection of lead H3 & Fan Motor.
What exactly does "Insulate" mean? because according to the wiring diagram I connected the White wire to left side of the switch (H1) the Black wire to the right side of the switch (H3) and then connected the red wire to H2 and bolted and taped them together off to the side. If I connect just the black wire or just the red wire (only one at a time) then the welder works but I am only getting 36 volts at the stick.
DOES THIS MAKE SENSE? Can anyone post a 500 kb image of the wiring diagram for me?
