Need wiring diagram for buffalo 110 amp. arc welder

They do not make it available. So a generic wirefeed such as this will be reasonably close.

Rarely will the circuit board schematic be shown. If however your wire feed circuit stopped, usually it is the SCR's that fail and they can be replaced with comparable units, or even higher voltage and current ratings than the original within reason. is a global vendor.

Hi well if it is blowing fuses and you are using it on a suitable circuit breaker, a FUSE really isn't suitable, unless a special Motor type slow blow fuse, etc esspecially with this much current draw, anyway if this is occurring the device must be short circuiting after it arc's, accordingly i would imagine that one or more of the output semiconductors, is shorting at this time, the only way to fix this will be to replace these semis? & possibly the drive circuit too? It's impossible to actually tell without actually examining the unit as i am sure you must understand?
However DIY in reality isn't really practical, unless you can obtain a service and repair manual, and then you maybe able to isolate and repair the unit, however in my experience the very best thing you can do is take it to a professional and get a "Quote" as top prospective costings and go from there? This way at least you will know what's wrong and how much it will cost, it may even be that replacement is better than repair in any event.

I have an ancient 125 amp AC arc welding machine on which the current is varied by moving the negative lead from to different terminals. However the terminals are in pairs and joined by slotted metal...


Since you did not mention here brand or model of welder; I'm pretty sure that your machine it's an AC/DC machine, the series of slotted plates means that the machine will output 50 amps in AC or 80 on DC. 60 in AC or 125 in DC.
If you want to work with lowest amps available, just put the selector on AC and connect your cables to the 50/80 amp side.
You should have a selector lever to switch back and forth from AC to DC in front of the unit.

Hope this work for you.

Problems with welding with a Forney 180 amp. Arc Stick Welder

check your input power connections on the primary side of the welders transformer, then if its an infinite control welder check that control,otherwise if it's a plug- in selectable amperage check these connections,it sounds like the infinite control is getting dirty and not passing all the current it shows on the control, also double your O.C.V. on the secondary and see if its with-in welder specs
