You WILL notice a difference using a .023 (some make a .024) wire, over using a .030. Does much better on thin metal. What kind of wire is it? Solid, flux-core, flux-core gasless...and are you using gas?
Solid wire with a argon mix. Standard MIG setup, not flux.
Seems like the preference is the thinner .023/4 which I have a ten pound roll of. Will switch from .030 and see how it goes.
Thanks for the feedback.
