found this site just now, maybe helpful to people who are just starting to weld a chassis?

http://www.mig-welding.co.uk/

good info on mig welding steel, and aluminium, setting current, wire speeds, what patterns to use, all good info for the beginners (like me!)

Very useful mate.

I, for one will be buying me a new MIG welder next week, I've used gasless since i was 14 for tacking (although mine has had very little use over the years) I think its time to move up. was looking for info on mig welding aluminium, and found that site. handy video clips on there too
