Lincoln arc welder AC-225-S (wire disconnected from on/off switch??)

admin

Hello,I just picked up a used AC-225-S from FB marketplace.  I'm new to arc welding, but I tried out the used welder and it worked okay.  Then I must have had something goofy going on and it tripped my circuit breaker.  I reset the circuit breaker and continued on for a few minutes and it was fine.  Long story short, I tried to start the welder today, and there was no humming, etc. to indicated the welder was active.  I checked all the usual spots and I do have power right up to the on/off switch.  So I opened up the welder and the first thing I notice was a red wire labeled "H2" which was not connected to anything(it had a blade connector on it).  I imagine you are saying "Get off your duff and connect it!".  Well, I am confused on where it would go?  There might be an insertion point on the on/off switch, but I am unsure.  Plus the blade connector is inside one of those heat shrink rubber protectors.  So I just could not see how it would easily connect inside the on/off switch.  But the length of the disconnected wire only seems to reach the on/off switch.  Please see the picture attachments.  Thanks in advance for any tips, Steve
