Many years ago I welded with 7024 drag (jet rods) rods that were 36 inches long on cargo ships.

I have only welded with 7018 and 6013 welding rods. I had no idea welding rods were as long as 36" inches let alone 4 footers!

My bad. They were 7024 rods.

That's not a puddle, it's a lake!
Steel mill I used to work for used 36 inch wide electrodes that were 20 feet long and would screw together to melt the scrap steel into a 300 ton puddle. This was called an EAF or electric arc furnace if your interested enough to look it up.

EAFs are impressive and frightening!
Arcing and sparking all around. It's been years for me, but I used to help run/service onsite oxygen plants at steel mills, etc.

You could weld the crack of dawn with an electrode that large!
Wow! Its still red while they were chipping away the slag!
I'm surprised a regular welding helmet is enough, could you even use auto darkening or would the brief flash be too much? Has to be a lot of UV coming off that rod.

Thinking the filter shade has to be a 12.

I remember when I was an apprentice, our class took a tour of Finkl Steel in Chicago. They had a huge carbon arc furnace they melted scrap in. They were just finishing loading it when we showed up.
The guy giving the tour said we would stay to watch the initial start up, it would be worth it. They loaded just about everything into that heat. From old engine blocks to just about any type of scrap you could think of.
When they finally cranked it up there was a loud crackling roar, and you could hear big pieces and whole engine blocks banging around inside. He told us the amount of electric it consumed, but I can't remember what it was. He did say it was so much that in the Summer they only ran it at night, because it was much more cost effective. This was back in the early 70's.
In the Summer it got so hot in the place, that the guys running the open die forging presses could go home without an excuse if the outside temperature was over 90F.

The shade isn't what protects from UV and IR even clear plastic protects from UV and IR. The shade is for comfort and to see the work clearly.

For comfort? I guess like keeping your eyes from the flashes.

Been over 30yrs since the shipyard for me,new work mostly. Main deck and hull seams were Veed with a track torch and then welded by a tacked welder running 1/4 wire through a bed of flux.Largest stick were 7/32 x 2'
I was able to bend 20-3/32-7018 rods behind my neck.
