The part no. for a 10 # spool is TGE5 and to avoid confusion that Twenty (NOT 20) gauge name is just that, the name of the wire and it does not refer to the size of anything. If you do use solid then go for .023 but the Twenty Gauge .030 will be a lot easier to use and because it is a cored wire it uses even less current in that size as the smaller solid wire.
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.
