    Thanks for all the replies. I was aware of the "block of wood test" for setting the roller tension and that is exactly what my machine would not do even with the tensioner tightened all the way. I also realized that this would destroy the feed motor. I took the suggestions and started from there. When I adjusted the roller alignment I was able to back off the tension and still get proper feeding against a block of wood. So in this case the alignment was off and you could see that it was quite easily when viewing the roller from the top of the machine. Cruizer, the knurled roller makes sense, I will do some research and post the part number for anyone who might need it. As an aside my MM252 came with a 12' M-25 gun and I replaced it with a 15' Bernard 300 amp gun. Again thanks for the advice.

    I'm glad you got working! I sure like mine. I did about a half hour of welding on some brackets yesterday to hold steel tubing for a project that I'm doing. The machine welds beautifully and is a delight to operate. It's a keeper!

    I found the drive roller kit for 0.35 wire the number is 079-606. Please let me know if this is the correct part number. In addition Cruizer said to use just one roller, is it possible to just purchase a sinle knurled roller. If so does anyone know that part number?
    Thanks,
    Nick

    Here is a link to Miller Mig machines. Somewhere around page 18 there is a chart showing that P/N 079-606 is a .035 V-knurled for hard shell cored wires. They give numbers for a 22A kit (079-606) and a 24A kit (046-792) but I don't know the difference. The roll kits come with two identical rollers.

    Be patient when downloading the link. It takes a while.

    If you really want a single, v-knurled drive roll,

    But, according to the manual for the 22a and 24a wire feeders (which use same drive rolls as the 252, at least on 2-drive rolls), the knurled rolls are for hard-shelled cored wires.

    The wire feeder manual is here

    and has much more complete info on this @ page 33 or so... Steve

    Oh, the 24A kit is for a FOUR roll feeder. The 22a feeder has 2 rolls, same as the 252.
