I still have that box somewhere in storage . I need to try it again using copper ball bearings.  I think copper might work really well for certain small parts provided they don't fuse to back side

I think you covered all the main things. I think one of the main things is lingering too long while fiddling with a flimsy filler rod.  Back in the day, I would use .063" (1.6mm) ams4951 wire on this thickness with good results and no melt thru. The .045" wire is better for a smaller bead but I just liked the bigger wire for stiffness.  thanks

Very cool video Sam

I love digging into the science but I’m not sure I’m even scratching the surface of the physics behind it. We will keep the conversations going

that's my friend Lee.  an old friend of mine.  makes filming video a lot more fun than filming by myself.  We went to welding school together 45 years ago so I might just do a podcast with him reminiscing about the old days in school.

I will upload a video on feeding in just a bit...here it is https://welderskills.com/programs/ws-feeding-tig-rod-9b7465

Nice work

I will bring your question up. Brad has a great understanding of this topic

Rule of 33 works better on steels.

Thanks Martin
