Great project, and nice job guys!

What gas are you running when welding DS with the Lincoln Outershield that JD mentioned? Great info guys, thanks!

I'd like to try DS on my ESAB Rebel 205 AC/DC, but it has no DS settings that I can find in the menu. Forgive my ignorance, but can I simply use it in the standard GMAW mode, and set the volts/wire speed/inductance manually, that way the gas solenoid works as normal? I'll assume that I should use the knurled flux core drive wheels as well? 

Great video Brad! Are you ganging the 12 bottles of N, due to the shear amount of cutting you do on that 5'x10' table, or is it to prevent the 95psi from dropping while cutting?

Real nice repair, and explanation of why you did it. Good work!

Sam Gotcha, thanks Sam!

Really helpful info Brad, thank you!

Great explanation of how AC frequency affects heat input. 👍

In cases where welding on a casting is problematic, is boring the hole out oversize, and install a cryo'd sleeve in a hot casting an option?

Beautiful! That finish on the last bead was excellent.
