Like a few have mentioned, 0.6 should be fine for mini bodywork.
It is just a matter of not trying to do long runs, I'm no welder, but I've done bodywork on 4 minis now and the trick seems to be very short runs joined to keep the heat down.

I agree with short runs if it's a big flat panel.

Must say, I use 0.8mm wire, with co2/argon. Seems to work for me with excellent penetration (heh he). Practice makes perfect, PLEASE get it right on scrap first, you're just making extra work for yourself!
Every machine is different, you'll only know when the settings are right by trial and error.

I recommend the auto-darkening helmet too, makes it so much easier

I use .8 gauge, for everything. Not sure if that's the ideal, but it's what I've always used and not had any problems on panel work or heavier stuff.

on my car i use 0.8 and it works fine just short tacks

and then at work i use 1.0 or 1.2 for heavier stuff right up to 50mm steel

My brother spent many years as a welder and fabricator and has also spent many years welding cars at the mot station he works at,he told me to only ever use .8 and i have had no problems with it.Used to struggle a bit sometimes with the .6.Been using .8 now for about 3 years with just co2 because its cheaper about 15 quid for a pub bottle size.

I do shed loads of welding with very little trouble.

I love my spotwelder though if i can get it in.Can't beat having nice spotwelds down the wings and sills to door step edges.

I also do loads of welding and always use 0.8 on everything from mazdas to minis. Make sure the earth strap is in good condition if half of the wire is hanging of it won't help the quality of welding. Having the welder set on the lowest setting only a starting point and the moe experienced you get a t welding the higher power you can use. I can do pretty much the same welding job with power setting lowish or relatively high. I think it's mostly experience then you know/see and hear when a good job is done. Remeber the power cycle is low on a cheaper welder meaning power is actually getting lowr under continuous welding.

Ive got hang of things now and settings, and also the fact that i can now see helps as i got some better lighting around car. havn't got much wire left so ill probs get some .8 and see which i find best.
