Whilst flicking through the frost catalogue I spotted this.

Would this be ok for general welding on a bug, seems a bit to good to be true. What are the advantages/disadvantages with MIG v ARC welding?

not suited for automotive repairs. It's for thick metals, no good for the thin sheetmetal a car is mostly made of. MIG is the way to go.

Arc welders are unbeatable in heavy duty construction and especially outdoor work, where the slightest wind would blow the shield gas of a MIG away and render a MIG useless.

Arc is for fenceposts, not capable of welding what "we" generally would need to. (Some pros with 30 years of arc experience say they can, but what good does that do ya). The heat produced by an arc welder is too much for thin sheetmetal, it will burn through, and/or warp the surrounding area.

An arc welder also produces TONS of "flash" or slag, hard crusty residue that likes to stick to the metal around the seam. Takes some extra labor to get it off. Again, if one was welding heavy steel stock, a pro with years of experience could reduce this problem as well. And once again, deducting from the fact that you needed to ask, I dare guess that you are not one.

Thanks Jan,

I've done some mig welding in the past but wasn't sure if that welder would be worth the expense. I'll keep saving & get myself a decent mig welder.

Again thanks for the reply
