Really good info there Roy, thank you! Have you ever tried stuff like painting on Solar Flux for protecting the back side of a weld like that? I have a can, but have not tested it out yet. I suspect it will be a mess to clean up afterwards. I suppose it's a matter of A.) Is it effective for starters, and B.) Is it still a time saver over fussing around with improvised barriers and gas? 

Cool to see an Alaskan WS instructor! ( I live in Wasilla ) Welcome. Would be great if you could do some instructional info and expand on the use of Silicon-Bronze MIG. I volunteer on a steam locomotive restoration, and that sounds like it could be a hell of a time saver, over gas brazing to build up wear surfaces.

A little Flex Seal on there, and she'll be water tight!😀

JODY COLLIER Thanks Jody! The starting setting will be great to work from. Also watch JD Brewer video. Very helpful!!

Thanks JD(and Joey), appreciate you guys bringing this video to my attention! Good stuff.👍

Brad Goodman Thanks Brad.👍

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?
