Actually posted this on my first post but figured it needs to be here.
aluminum backed, no filler, 3/32 e3 sharpened to a needle point, 15 cfh, 5 amps

dsmabe, that is beautiful!

Can you tell us what machine you used to accomplish this, I currently only have a dialarc 300HF that was built in 84. I have been very successful welding all materials I wanted to far down to some thin stuff but only about 24 gauge steel.

It's lowest setting allows for some very fine arc control starting at 10amps per the dial, I would not bet the farm it is 1000% accurate but I am able to start the arc and keep it cool enough not to even puddle of the material until I ramp it up with the pedal.

Razor blades will be next to try, that weld is flawless.

The brand of razor blade makes a difference. HF and China made blades don't work as well as s better quality ones.

is anyone welding these without an inverter machine?

If any of you can stick weld one, I'd be impressed. Where is the dude that was stock welding rusty car bodies? I haven't heard from him in a few months

Maybe with some 1/16" 6013

I would think it would be very difficult.

Yeah. I was thinking that too... I was being serious though, if anyone could successfully do it, it would be the dude from eastern Europe that was welding that Opel sheet metal.

Sam,
I'd be willing to try it, will have to look and see if I have any 1/16" 6013, or 1/16" anything for that matter. I do have some SS rod, I could try that. Will give it a go Monday if I don't forget.

I think they have even smaller stick electrodes that are made for the cheap $99 110v welders

Are we allowed any trickery that we can cone up.with for this challenge?

If something is silly but it works, it's not silly.

Well, technically, they're welded. 2x Stanley knife blades and 1x cheap azz hacksaw blades.
2mm 316 ss electrode at approx 20 amps. Power arc 200.

Now I never have to do it again.

Superiorwelding · Tue Sep 30, 2014 9:09 pm

Mick,
Looks, umm, good?

Did you use any backing material like copper? I plan on using copper or brass when I get to try it. Not bad considering the process really.

You're thinking of Djorge (qwerty12), the Bosnian Serb. Haven't heard from him in a while.

Clamped to a 20mm block of alum. Cant say I expected it go any better.

Second shot at razor blades. 1/16 tungsten and filler. Set machine to 25 amps and used a foot control, not sure about exact amps

I might have to try adding filler next time, i just fused mine.

O-1Stroke · Fri Oct 03, 2014 8:22 pm

That's a nice job on yours with no filler. I never even considered no filler. Ill try that next time.

Been seeing this so thought I would give it a try, considering I am using a Dialarc 300 from the mid 80's I was not sure I could do it due to lack of the arc control on startup.

You can see on the left where it just blew through the material on first try, I started again on the other side but started the arc on a copper spoon and gave the material a copper backing to absorb the heat.

Was very surprised how easy it was to get the bead running once started, this is my first time ever welding something this thin.

I then played with a bead along the edge etc just for the hell of it.

I thought I'd give this a shot. My first attempt isn't fit to be seen by anyone

This is my second try using my Miller 280DX set on 30 amps and using a thumb wheel amp control. 1/16 E3 tungsten. 10 CFH argon. .030 ER70S2 (6?) mig wire for filler. I was shaking like a...a...something that shakes a lot.

Eldon,
You where shaking like a dog shitting, wait for it, razor blades.
