.23 flux-core - Less Chance of Burn Through?

[kfriend]

When working on thin sheetmetal (such as autobody) will using a thinner flux-core wire such as .23 give you less chance of burning through?

[Ed Heimbach]

I've used .023 on autobody sheetmetal to very good results. I run this wire through my miller 30a spool gun.
I find that flux core works better for me on autobody sheet metal than solid core, this I attribute to the fact that flux core will tolerate a bit more dirt and paint than solid wire

Do they sell .023 fluxcore wire?

[kfriend]

I've found .24 and .25, but not .23.

Reason I asked was I was reading an article on doing suicide doors, and I was looking really close at the authors pictures, and his tacks really closely and it appeared that they were kind of "hollow" in the middle...kind of made me think of flux-core wire. He had stated he was using .23 wire, but not state whether or not he was using solid or flux core.

Third picture on the page, where he's doing the hinge pockets...I'm not really experienced, but it LOOKS like flux core to me.

Can anyone confirm this?

being a newbie welder.. my HH175 solid core .23 with c25 doing spot welds like that often get the same dimple in the middle if i get lazy with my gun technique (not lifting as i release trigger)
