0.030 wire is too small for welding 3/8” material. 0.030 can only carry so many amps until wire speed has no more effect on amperage output. With the wire feed speed in the 400-500 range you are well above the maximum current carrying capacity of this wire and joint penetration has not increased as one would assume. You are however depositing more weld metal on the surface of the weld. But penetration is limited.
I don't think that applys to pulse mig as the current is a average between peak and background. That would be interesting to experiment with. Perhaps I can do a video experiment with this. I have used smaller diameter wires on pulse and achieve high amp outputs.
Ok

Thank you for the information. Very much appreciated
@@dragonweldingfabricationll8080 interesting. Yes make more videos and experiment. I enjoy learning from others.
