"The American Welding Society (AWS) considers metal cored electrodes a part of GMAW, although metal cored electrodes are grouped with flux cored electrodes by foreign welding associations."

Kind of *** for tat.

That AWS section is referring to the "duel Shield" wires and NOT the Flux core self shielded wire which is NOT metal cored. Referring to self shielding wire as MIG only causes confusion and will not reflect very well on someone who does if talking about welding in a professional manner.

The Twenty Gauge is a "cored" wire but not a "gas-less" wire and requires the same C25 gas as the solid wire, also the polarity must be switched when using gas on either solid or Twenty Gauge.
LOL. I agree
Hey oldred did we not have are first talk on this one. It funny everyone has lump these to process together. But where it when wrong is you can weld flux core on a mig welder. So its miss used as to what one is really doing. Should not the welding machine say mig and flux core welder not just mig? The term mig is so miss used today.
So for the new people to welding read the posts on welding a lot of good stuff to be learned.
Go to your local welding supply do your home work tell them what you planing on doing they can get you a welding machine to fit you needs. Heck ask us old welder guys before you buy something thats not going to work for ya.

Take your time. Make couple short tach welds, put it down, come back do it again. Never let it get hot. Take your time you don't need heat sink. It is only something you have to clean off the metal latter. Take your time grinding . You can warp it just as fast gringing. Grind a little, put it down, never bear into it.

No warpage, no need for hammer dolly work when done:









Etch primer no filler, just after it was ground down:

See this is a guy with a good approach to welding body panels take you time don't get in a rush. no filler thats real cool. Pictures to boot.
You get one heck of a at-a-boy for doing all that welding.

Like Chevy said converting to MIG is about the only real option but some people do this successfully with flux core, it takes quite a bit of experience and even then it does not produce the best weld. On 22 gauge it could be a real problem

If you can possibly convert to MIG I guarantee you will not be sorry as the difference is nothing short of amazing. If you do convert then use the .023 solid wire until you get the hang of it then switch to Twenty Gauge and I think you will find you can weld better than you thought. Doing this conversion is not at all hard nor is it all that expensive to do with that little Lincoln which BTW is a good machine.

It can be done I welded caps on the stake bed pocks for my sons truck with flux core wire only because I ran out of CO2. I had a couple of burn through spots even being care full. Again if your not welding all the time you will get a little rusty.

Thats what I have in my Garage the Hobart. I have mine on the old work bench. I'm working on building my mobile cart out of 1" tubing. I have the material cut. But still know time to finish it.
I was thinking of buying one but hate to spent the 50-80 bucks for the bolt up ones.

I've never heard of the JW Harris 20 ga. welding wire. I'm sure it was nothing special you can't already easily find.

Your best best is to convert the welder to gas if you haven't already done so. Then and only then will you have a welder that can do it's best job.

Welding 20 ga. is very difficult. Why make it harder on yourself than you have too? .030 wire or larger is too big for that light material. You need to be using .023 wire.

Practice on some extra 20 ga. you have laying around. Get your welder set up so it works well for you. You will never be able to do a solid weld on light material without warping. Tack welds are the only way to do. Even then you will probably get some warping. Move around the panel to distribute the heat.

This is where you need to work the metal with a hammer and dolly before all the welding is finished. This will give you the best end results. Practice, practice, practice. Make sure the seams are as tight as you can get them. You will easily have enough penetration even with tack welds. Check this on your practice pieces.

Be careful grinding the panels when you are finished. You can still easily warp a panel after the welding has been completed with too much heat from the grinder. Patience is key along with a lot of practice.
