wow, thanks for your diagram hen...that was exactly what i needed to see...and thanks blown86 and cerby and anyone else who put in their 2bobs for your help too...
i'm not sure what you call the welder i'm using...its on of those (sort of new style i think) where the wire feeds through the nosle by the push of a button and you can regulate the heat and the speed of the wire etc....this welder is suitable isn't it? (i hate the ones with the sticks...i can never do it right)...also what kind of metal is it that i'll be welding? should i just use a mild steel wire or would it be ok if i used stainless wire?
