    Do not read between the lines, there is nothing there!

    Don, Thanks for getting back Don. I like knowing what finally fixed it. However, I assure you no argument was EVER intended on my part. Why would I fight with Kevin anyway? He is in perfect position to provide input as to what information we operators of their equipment need in the manuals they produce. That is the rational behind my questions. Better manuals. I felt no fighting was started and thus I was not ending one.
    If what was in the manual for your serial numbered machine was actually what you had under the cover of the machine, all of this could have been avoided. I'm glad Kevin posted with additional information to help get you welding again and I took an opportunity to improve their literature for all our benefit.
    On top of that I thanked Kevin twice. I will do so again. Thanks Kevin!

    On this note the questions of my prior post still beg an answer.

    NO FIGHTING NOW!, I downloaded one manual said it was a 1985 machine 230/460 machine.Miss placed that manual ,downloaded a second book when steve asked for the numbers,said it was a 1987 machine 220/230 volt. my machine has 3 jumper lugs,wired center and right ,pulled trigger 12 volt to relay and just buzzing ,thought 230/460 machine wired 460 half voltage etc.,switched jumpers ,loud buzz!!!!!!definatly not right. book says wire according to decal.Surprise ,used in shop all decals long gone.I need to get it going ,so it went the welding repair shop on the 13th. But if you have any ideas please let me know. I will also post the outcome from the repair shop.

    Thanks Don

    Goodness gracious!

    Miller Kevin, Thanks for pointing that out. Makes sense to me.
    However we have a problem. I down loaded the operators manual for Don's machine using it's serial number. I checked it twice to be sure and double checked the serial number. The manual refers you to the name plate on the machine for sure I will grant that. But the circuit diagram only shows two input taps, one for 200 and one for 230volts and no taps for 460.
    My questions are these:
    1. Could you down load the same operators manual that is available to me, read it, and using only that info advise Don correctly?
    2. Should I refrain from assisting people with welder problems using only Miller operating manuals as this one is apparently incomplete as far as the circuit diagram goes?
    3. How can I use my electronics expertise to effectively render assistance to others?


    If Don had the same manual I downloaded, it's no wonder he's scraching his head. Good thing is I got him to the input power even If I didn't know it was a 230/460 machine cause as far as the book goes , It's a 200/230.
    Thanks again for setting it straight.

    Don,

    I had the serial number checked and the unit you have is a 230/460 volt machine. I am pretty confident that it is linked for 460 at this point and that is why all of your control voltages are halved.

    Check the primary link board inside the unit, there is only 3 studs and the jumper should be on the middle and left stud for 230 volt operation.

    Kevin

    Finally caught on to PMs. See public apology thread. Got correct print. This Millermatic, according to the manual and serial number, originally came with three prong polarized plug with outlet provided. The input transformer only shows jumper for 200v or 230v. I think some one else put a different plug on to fit their outlet.

    Cut and pasted from Miller Motorsports board:

    Sombody on the projects board can't get output on their mm200.
    I'd like to suggest they check the input "jumpers", if it came from
    a larger shop they may be set for 440volts rather than 220/240.
    If anybody can cross post to that board please pass this along.
    I don't have time to register right now.
    Thanks
    Dave P.

    Go from the known to the unknown

    Ok not waiting. Understand I am using the generic prints for your Machine. This information provided may not be correct for your model.
    A recap: Wired for 220, turned on machine and had buzzing noise, Relay in top of machine not closed so replaced it with with same problems. Checked across relay had 12 volts.
    Using a generic print for the Millermatic 200, It has 4 relays under the hood not withstanding a few on a circuit card. Relay W takes 115 v off T1 to operate. It is the main contactor used to turn on the welding current. CR 1,2,3 are used to control various unknown functions to me but are 24 volt relays. There power comes crost CB1, CB3 from T1. This should be 24 volts at 30 and 31 from the T1. If you have 12 volts then you need to check S1 5 and 6 for 220. If you have 115, you need to rewire your input plugs. You might be feeding the machine 115 volts and not 220. Happy hunting.

    thanks steve ,I will write them down when I get home.If I recall correctly it checked out as a 1985 millermatic 200 with all options except spool gun. I will get the numbers and get back to you to verify.

    Gonwhln, If you will provide the model and serial number of your machine, I will down load the manual, go over the prints and maybe can give you some more places to look. Steve
