It's only going to be used for body and chassis work

i would go with the smaller wire for body and the bigger wire for chassis
is it a brand new welder?
what is it set up for now?(drive spools,torch tip, and hose liner) often if the liner is set up for the bigger wire you can run the smaller wire without chaging the hoses liner.
you will just need to change the drive spools and torch tip, when you switch wire.

but thats just what i would do
you can use each wire for both body and chassis

It is funny cause we all have done that type of thing. I personally have never done that one but I have my own stories. Got to be able to laugh at yourself.

The welder's set up for the higher gauge

I'll switch to the lower

Is it just the drive spool and tip that need switching out?

What's a drive spool anyway? Is it the small wheel inside the body that the wire feeds through?

yes the little wheel inside, that guides/pushes the wire through the torch hose/handle

you should confirm that the only things needed to change is the little wheel and the tip of your handle, in the owners manual or check with your welding supply store

if you have to buy other stuff to switch it (spool and tips) i would buy both size wire, because it will be easy to switch (you already have the big wire stuff)

I set my jeans on fire a couple months ago and Ive been doing it over thirty years...(welding not setting myself on fire) The guys are still lighting matches and saying hey whats this??? its Mikey on fire............It happens....
I still remember how it felt waaaaaay back when I bought my first set of ox/ace torches ....Your batman....

my only advise is buy something brand name, miller, lincoln,or hobart, etc.
good welder = good welds, cheap-o bad welder = bad welds
