I'm going to buy my first Mig welder. I have used various ones occasionally at my job for 30 yrs. I have an old stick machine. I am down to these two which are literally within $30 of each other. I am starting a vehicle restore which will require work on thin stuff and basically do the usual mechanic tinkerer repairs. Miller guy says his blue one is more durable and sells both. Lincoln guy says his red one has better product support after sale and sells both and is the authorized warranty center for both. This is the classic Ford vs Chevy/JD vs IH/ Mobil vs Rotella type question, so please keep it civil. thank you
