Thank you Jody. BTW I used plasma off a mobil rig ONCE, bought a reg, used it off a single tall bottle of nitrogen, it's sucks it up pretty fast. But gets the job done. Wanna make sure there no leak$ in the fittings. Like you say "quick and dirty" . Also it can be handy to have a bottle of nitrogen for blowing stuff out.

Mobil Fire extinguisher refill guys use nitrogen to recharge several extinguishers on site.

More info on that flux information would be awesome 👌

We're those oxy-acetylene settings said to be 7&7 or 7 & 70 ?

I think I need safety glasses to watch this video.

6010 is funny, tight arc for roots/ groove Welds and and a variable 1/8 arc gap for lap joints and such. That's my two cents, I'm no pro-instuctor but yeah flatter weld usually happen with a decent 6010 arc gap. Also look into 6010 5p (red) it's supposed to be good old rusty dirty steel.

Run 7018as hot as you can control the puddle/bead.

Wishing him well too.

Not sure what you mean by all under D1.1, but from my understanding..

D1.1 covers structural steels and different joint parameters, meaning the beams may have a different base metal content which will have filler rod , processes and preheat parameters.

Same for the angle iron too. Only with the joint configuration there may be a minimum weld size listed as well . I'm no inspector so I can very well be wrong , but for sure D1.1 covers base metal, weld size requirements, preheat Temps

Pre-qualified joints, ect, but not beam sizes.

By the way thanks for the input on my last post I found it insightful as well.

Ok , 10' more ft of sch 80 .75 pipe and some expanded metal , few hours later and I'm ready pull bait 🤪. This is just for fun, but it work it's a plus #idontevenfish

Nice looking weĺd there for sure.
