Is that set up built from a steak welder cup ?

xXSanderXx

I'm a beginner and definitely need a foot peddle.

Luserkid

It is made from excess of a part we make jb welded to one of my weld cups.

This is my cup and collet box.

This is what I use for all steel, stainless alloys, and inconel alloys.
Small gas lens, #12 cup. White scotch brite held on by a ss ring, usually run 35cfh.

Only time I change my setup is for welding aluminum.

Is it better than a lense? Certainly uses more gas? I don't figure how the pad doesn't melt!

THIS is what I have been looking for. The SMALL lense #12 setup. I didnt want the large lens #12 setup. Where can I get that for my #9?

ghostchild316

Incase anybody else is wondering, the no.12 small gas lens cup is made by CNI www.ceramicnozzles.com

It is part # SP-20070

Would the smaller gas lens with the #12 cup function and provide as good gas coverage compared to the larger size/diameter higher flowing large gas lens with the #12 cup?

I personally never got great results with the #12 on the medium gas lens. If you ever saw the flow from a gas lens, it comes out like a "tube" of gas. So if the cup size gradually increases, I don't see how that would work. That's my guess as to why it doesn't work as well.

Maybe that's why you guys are using extra diffusion? (the scotchbrite),.

if anyone has time i dont have pics but try this. I use a small gas lens and take a #12 big cup turn it around and the small part of the cup will slide snug over the cup you use. i use a #8 then i put a piece of white/green scotchbrite inside the cup where the threads are and it holds it in place without falling out. I run 35cfh also with perfect coverage. wish i had pics to show. all in all got around 8 bux into it instead of 30 for a big gas lense or champagne nozzle for 80.


p.s all done on a wp20 torch body

Yes the extra diffuser is mandatory with the larger cups.

I first started with a brass screen pushed inside the cup. It was ok.

Then I switched to white scotch brite. Better.

Finally scotch brite over the outside as shown. This worked the best.

Its the diffuser that's doing all the work. You want the gas to have the least amount of turbulance with the most coverage.

It works great, I even use it on welds that get radiographic inspection. Excellent on tight areas/joints as you can stick out the tungsten quite a bit.

If it made my welds dark/black, I wouldn't even be running it. I'm not that kinda welder

batboyvaj

with a #12 I've tried 15-25cfh and my welds were always really dull and gray. So I stuck with my #8 and my welds are fine? weird

Flexer

On Sch10 SS pipe, what size tungsten are you generally using?

SLMachine

I use a #8 cup 30-35cfm 90% of the time w/ perfectly fine results in my opinion. Control your heat, travel speed, and torch angle and most your problems will solve themself. For the new guys in my opinion throwing on a huge cup is just a bandaid to poor habits/technique.

I also use the No. 8 cup....exactly the same as Agtronic....and I don;t have any issues with it.

Agtronic

Don't get me wrong, I get great results with the #12 on the LARGE gas lens, but not on the medium one. I don't believe a cup with a larger outlet than the size of the screen inside will ever be able to give you the results you get with the large lens. (Unless you run another diffuser at the end like the white scotchbrite posted above.)

RadekSkylark

Did bit of welding today and found out that 9 l/min (19cfh) works best for me with normal tungsten stick-out. SR9 Torch, large gas lens, cup #12.

SovXietday

That is a lot of gas flow, when I can get the same if not better results with ~20cfm on a large lense and #12 cup. I can also travel much farther on pipe and get a consistent color, whereas with the #8 I was using never really gave me much range.

Boosted_B_Series

Little update on my gas flow. With my #12, I normally use 15cfh for normal stick out on just about everything, and 20-25cfh for excessive stick out.

But, today I was welding some really thin stainless with normal stick out and 15cfh just wasn't enough. 20cfh worked much better and got me the color I was wanting.

I normally just try to use as little gas flow as possible to save argon.

Flexer

Just currious..... I usually use 1/8th tungsten size for sch10 SS. Is this the size you guys are generally using?

HellaFab

1/16" good for pretty much everything up to the limits of my precision 185

EJAYATE

I had to get one of those champagne cups after seeing everybody had one. First weld turned out ok but its a little strange moving with such a large cup when im used to micro torches.

EJAYATE

I feel like i would get better coverage with a straight barrel large
Cup with large gas lens instead of flaring out to a largr size. It doe work fine for what it is.

Boosted_B_Series

Damn what a weld, I can't even see the start and stops.

Where did you purchase the champagne cup/lens pictured?
