First post, new to this. I have a 1985 miller big 40 machine and it randomly quit welding without any sign of it quitting. Crunk it up one day and it would barely arc up. Wide open amperage would barley hold an arc. Took it to a local shop and they diagnosed it as being the diodes. I replaced all 6 not paying attention that three were different… me thinking they were …
I've been a hobby/farm welder for many years. I've always begged and borrowed engine drives to finish work here and there. I would like to pick up a machine of my own and start picking up some more side work. I really think I want a Miller Big 20. The plan would be to trailer mount it. Most uses would be pipe fences, entrances, trailer repair, etc.

I have a miller big 20 that runs but does not produce any power on the welder part or the 120v outlets. the auto idle does not work either. I unplugged the solenoid and it will go to low idle when the wires are hooked to a 12v battery. I have flashed the armeture with a 12v battery and it had a small arc when I lifted the wires. I tried plugging in a drill and turning it by …

The newer big 40's with the CC/CV option are the cats ***. The old CC only machines suck, but they have one redeming quality, you can take the F163 out of it and couple it up to a SA200. lol I do quite a bit of AC aluminum work so the big 40 works great for me. but if all you are doing is DC stick the SA200 will blow the miller away.
I got a miller big 40 and it wont hardly weld even turned up to 400 amp. It will idle up when when you strike a weld but it is pretty hard to even get it to do that. On high it will burn rod but very …

My 1970 Miller big 40 will start up and run but won't weld now. Just got done doing some work to the motor but didn't really touch the generator side of it except that I put a new range selector switch in it.

Hello, I have a 1996 Big 40 G with the TM 20 with 1255 hours. It has just stated to not come up to weld speed automatically when a tool is plugged in or an arc is struck. The power is fine and it welds fine when it is done manually. ... Miller big 40g wont come up to idle speed automatically 05-30-2017, 09:33 AM. Hello,
Ive got an older Big 40, gas engine. The engine runs great, but after sitting without being used for quite some time, it doesnt weld. If I turn the Fine Current Adjustment up to , it will weld, but not anywhere else on the dial. I would appreciate any advice. Thanks
So, I bought an old BIG 40 welder 1976 and I picked it up for a steal, because the old man who owned it couldn't get it running.....4 years ago. It sat outside the back of the shop since then! So he sold it to me for a 100 dollar bill. ... Miller Big 40 Welder NO POWER from generator side... 01-22-2022, 09:10 PM.
the welder uses three brushes. center is common. one is the weld and the other is aux power. clip a meter to each set of brushes drape leads away from anything that moves and start it up. measure the DC voltage on each set. make sure brush is making contact with the slip ring. a stuck brush or very dirty slip ring can cause your problem. start with the excitation circuit.
OK, I've been going back too far in diagrams, you still have 2 boards, one is a voltage field board, the other being the idle. The idle board in question may not look like a circuit card (over serial# JH300534), rather it will be a little 1 1/2"x 1 1/2" red (or black) module with 6 terminals on it.
miller big 40 Back from short trip. Checked continuity from slip rings back to rectifier. All checked out at less than 1 ohm. Additional history is unit was working, was towed a few miles and engine would not start. Fuse at hold in to start was blown. Fuse was replaced but welder has no output. Is this and indication of some component failure?

I bought this advertised as a Miller Big 40 that would run and generate 110v but would not weld. There is no plate on the unit and it has been covered with black paint. I am first trying to find out what it is before I begin the trouble shooting process. Several folks have had it. Last seller could not get it going. The person he got it from could not get it going either.
