Though I noticed yesterday that the deep-throat ones, ooh err, that would probably work better, are apparently "Malleable steel":

If I do it, I may spend a bit more and use these:

Sailah may well be right however.

Either way, they welded just fine. I think I used stick with 7018 rod. Tools like this generally aren't as important as a mission critical application (engine block or suspension component).

Are they supposed to glow when you're done?

9 passes without breaking arc. 2 guys on the same machine, each have our own stinger hooked up to a Y. Keep going in circles and passing the arc off to each other, change your rod while the weld is on the other side. No chipping slag.

I "Think" they are boiler tubes. I hope they are thick because I "think" I see undercutting on the red one.

They are boiler tubes. 2.25" OD, 1.25" ID. So 1/2" thick. The undercut happens when you run them out that fast, as the metal heats it will flow down and sag at the top. After the slag is chipped off and the tube stops glowing one more pass will dress the top up. They don't get left as pictured, I just wanted to get a shot of it glowing.

The reason we ring them like this is because rod angle is terrible on some of the back sides, and you can just barely reach it. Restarts aren't feasible normally, so we just keep the weld going. Sometimes just one round at a time, it depends kn the situation.

out of position welding

Back ground Im a gorilla welder welds are ugly and usually strong.
machine hobart champion


I want to weld some stake pockets to my trailer and cant get the vertical welds to stick.
I've tried 7018 1/8, 3/32 6013 1/8 3/32 with no luck
the frame is 5x2 x 11ga box steel and stake pockets are 3/32 thick

On the flat I can get 7018 to run ok (they are old rods) but on up hill they just don't stick.

Gorilla welder,

Both pieces need to be clean as in fresh ground no rust or scale, even mill scale. Keep a short arc and work your UP with a weave.

Vertical up is a learned skill. Get the hang of it then weld your stake pockets in. FRESH DRY 3/32 7018 @ 80 amps is what I would use. You could also use 6010 or 6011 but I don't' know how many amps. The machine should do the job.

It took ma a semester to learn vertical up. Once you have it, any position is a piece of cake.

Good luck
David

Thanks I'll get some new rods and try again.

Point the rod straight in or a little up.

Pics please

Just use 6010 rod run vertical up with a whip technic.

I've had good luck with ones from Grizzly. They have a little one pictured in their catalog(it's orange), but they have a bigger one that I have bought a bunch of that isn't pictured. I think they're like $15 each, and I can't break them.

That is a weld? Cripes, I have oxy-acetylene welds that look like a TIG weld and I do this as a hobby. I'll be plugging in my new Everlast PowerTIG 250 EX soon. I always wanted a TIG.

I don't know about 'water tide' but it looks like it'll hold corn at least.

Seriously though, I'd get fired for that. At the very minimum they'd pull my welding certifications. Might even get put on the next drug test.
