I have a 1985 millermatic 200 I need cr1 pinout
Here is a post that talks about the problem you are having.

SOURCE: millermatic 200 won't weld
first check on the plate that tells imfo of unit ,there is what is called duty cycle.If the duty cycle says per say 30%,that means you can weld full power for 3 minuets before unit will shut down to cool.if it says 100% duty cycle there is no limit on weld time.this is the first thing to understand,if that is not the case check the main contactor where the power imput wires go,pull the gun trigger see if the contactor is pulling in , it should if not no welding amperage.

There can be a few different reasons for it, but here are the top ones.
1. Remove the nozzle from the trigger end and remove tip and defuser. If you can. Some models the defuser is part of the gun.
2. make sure the lead is as straight as you can get it.
3. Check to make sure the tension is tight enough for the wire.
4. Make sure the spool tension is not to tight.
5. If all the above steps have been followed to no success, look into buying a new liner for the lead. When removing the liner check it for any major kinks or bends. Sometimes you may not have any but you can find a real flimsy spot by inspecting the liner and this can often cause a mis feed.
5. If
SOURCE: Wire Speed Increases when voltage increases
What is it doing? stabbing the wire into the work? The voltage is too low for the speed of the wire feed.. Turn up your voltage and slow down the wire. then increase your wire according to the speed of travel of weld. That is an awesome machine but it is still up to you to get the settings dialed in. Good Luck, Ned.
SOURCE: millermatic 140 w/ auto set powers on but will not
If its a new unit its probably nothing. Miller makes good stuff. Open the side so you can see the spool. With the machine on, press the trigger for a second. Did the little wheel spin (trying to feed the wire) if it did then your problem could be kinked wire, **** on tip, or spring on small spool is loose and wire is slipping. Let me know.
