Agreed, the MIG doesn't penetrate like a stick especially if you're using
5P. BUT that being said, plenty of snow plow repairs have been made
successfully with MIG. Pre heat is a good idea. Especially if just coming
in from the outside. AND if you're welding the high carbon cutting edge,
then stick with special alloys is really the only way that will last.

a. warm the helmet and lens first, your warm breath on the cold glass
is what causes the fogging.
b. use a MIG instead of stick welder, there's no smoke.

Be careful with that MIG. Unless you are using flux cored wire, it may be
difficult to get good penetration and fusion without preheating the metal.
And even with FCAW, I'd heat it up first with a torch, otherwise it
doesn't do as well. Steve's right about the smoke part, though.
