Hi all,
As my MIG machine is stored in a fairly damp environment, and I can't be bothered removing the wire after use every time, I've fitted one of these enclosure heating elements:

It's only 15W, which, by my reckoning works our at about 0.3p per hour, 50p per week, and it is self regulating at 70C.
They are designed for anti-condensation of electrical cabinets etc. and can be left powered on for years.
I've screwed it to the base of my MIG welder, and wired it through a switch and in-line fuse mounted on the back of the machine, connected to the permanently live mains input.
I've had it on for the whole of this winter, and not noticed any rusting of the wire like I normally get.
Oh, and I've also fitted a short 3/4" tube to the side of the machine and put the nozzle in there when not in use so that should stop the nozzle end wire and liner rusting as well, I hope.
Hope that helps someone else.
Cheers,
Robin.
