As above really looking for a decent mig welder but don't want to break the bank nothing to big as getting bored waiting for people to do it for me.

Unfortunately its a bit of a dilemma as a cheap welder wont be up to much, i had an SIP mig but anything over 1mm it wouldnt weld it very well, so i bit the bullet and spent nearly £600 on a decent set up but what a difference it makes, and second hand ones are few and far between, so my advice would be save up for a while and buy the best you can afford and you wont regret it.
