I pick up 2 rolls of wire today .o30/.035....Will I have to have 2 differant liners for my 251 mm..or will they work in the same one. and when will i have to change a liner for what size wire ...ex alu..going spool gun on that 1. Is it called a liner or cable?

I'm sure someone will correct me if I'm wrong. But I believe the MM251 comes with an "M25" gun, the same as my MM210. My gun came with a liner for .030"/.035". You have to get a bigger liner for .045" I run .030" in mine. If you change between .030" and .035" be sure to change to the appropiate contact tip.

Jim, you are correct.

You'll also have to flip the drive roll in the machine, as it is for .030 and .035. David

Been reading posts about wire sizes. Anybody out there got an opinion as to the best wire size to run in my MM210, .030 vs .035? Pro's and cons? Under what circumstances is one better than the other? I'm a newbie and have been running .035 with satisfactory results, I think! All things being equal, what will I notice if I swap to .030?

First things first: what are you welding?
For heavier materials (probably like 3/16" and up), use the .035" wire. For anything lighter than that, consider switching to smaller wire.
Truth is, I run .035" for everything CRS/SS, and 3/64" for alum. in my MM251. I am more than pleased. I have yet to try the thinner stuff on this machine, so I cannot say for certain how much difference there would be, if any.
But I tried everything on my HH175, and .035" was the trick. ;)

Most of the work I do with my MM210 is light, 1/4" down to sheet metal, both steel and aluminum. I use .030" in both the mig and spoolgun. Any heavier I still use .030". Really heavy, I use stick.

Just started using the Hobart Brand mig welding wire as recommended by the dark side forum. After many years of using brand "b" wire, I was quite impressed with this wire. Mentality was wire is wire. Not so. Less splatter, nicer looking welds with the Hobart wire. If you are doing autobody sheet metal, get the .023 wire. Less heat, less distortion and warpage. HTH
