yup it definately did when i had one.... i think i posted a thread exactly like this one, and that is why i went to lincoln wire
I've got a pick on my old computer that has a direct side by side comparison, HF wire and Lincoln wire. I just laid a bead of each on a piece of steel. HUGE difference! HF bead was dirty, had a ton of slag holes, etc. Lincoln bead was nice and clean.
