Does copper weld steel wire need to be longer than plain copper wire?

No, solid Copperweld (R) is electrically the same as plain copper wire at HF. If the wire is stranded, the copper plating may become thin enough that you start to see a little more loss that pure copper. The ARRL Lab saw this effect when we measured window line made out of stranded copper wire. Window line made out of solid CCS was more cost effective than stranded CCS.

Has anyone ever tried MIG welding wire? It comes in various diameters, the most common being .035 and .045. It is steel wire, but copper coated to prevent rusting. I have never heard of it being used and I was wondering if there is a reason why this is so?

It rusts very quickly in typical ham environments.
