Oh yes, you can't weld through rust or paint! Also I have a bottle of something like 80% argon which seems to improve matters greatly. I taught my mate here how to mig weld. Well, when I say I taught him, he got me to do a few bits for him, then I showed him how to do it and he was borrowing my welder but he got fed up with bothering me so he bought his own and now he's much better at it than I am
Take it steady on the outer, what usually happens is it puts too much heat into the metal and it expands and distorts. The almighty great mig at my mate's workshop has an adjustable timer in it to cut the weld every few seconds for this reason (it's bluddy hard to weld like that!)
I have two huge and two small cherries; 5 large, two medium and 5 small apples; 3 small pears, plus one peach that I've only ever had one peach off. Sometimes I can really see the appeal of concrete
