Mig troubleshooting for porosity

I'm having porosity no matter the settings on my machine. I've checked hoses, changed tips, been all over settings, etc. I'm not too experienced at mig; 25 years tig/stick. Some days i come in to work and nothing seems to work. other days, everything's fine. Help!


Swap gas cylinders and see what happens.

also , if you are doing open butt root welds, try using a smaller nozzle.
