90 amp HF welder help.

[Swamprat]

yes i know its a lost cause, but it was a free welder and it works! sort of, anyways im too retarded to understand the supplied diagram. can anyone with this welder post some pictures of how the speed controller should be wired up? or can someone help me understand it? i got it for free and the guys before i had it replaced the feed motor and bypassed the speed controller. which is inconvenient to me, but again free is free. so i'd like to get it working so i can fiddle around with steelmetal work and motorizing bikes and what not.


thanks

This is the basic one with speed control and a Min/Max switch for amperage, correct?

If you don't get info by this weekend I'll drag mine out and take a photo.

 

[Swamprat]

yup that one.

Is there a difference between the blue and the black one?

 

[GSequoia]

I'm pretty sure the black one is bigger.

Is there a difference between the blue and the black one?

not that i've found.

anyways i have the feed motor and the brown wires that go to the ground cable and gun right. but i cant seem to figure out why the two green wires go or the blue and brown one go either. obviously they dont go together cause nothing works when i wire them up

 

[Swamprat]

well i have it working, just had to rewire it like it was. now i have a single speed flux MIG. haha

i wouldnt worry about it too much, mine never leaves 5.5
min for sheet
max for everything else

 

[GSequoia]

i wouldnt worry about it too much, if I set mine above 5.5 it starts to stutter and feed like complete shit.
min for sheet
max for everything else

Fixed it for you.

thats what mine does unless everything is straight and not looped
