Welding Tips and Tricks

How a gas saver save the gas we used? By decreasing the flow rate? I mean, when we used Gas Saver we may decreased the flow rate to 40% compared to non gas saver? Or?..
Need info from you guys that used to use Gas Saver.
Thank you.

A gas lens diffuses the flow from your cup so that there is less turbulence. I use them almost exclusively.

When welding on the bench in calm air, you can get good results with flow rates down to 5 CFH. (Please don't ask me to convert that to LPM; I don't know that particular conversion.)

That's about 1/3 the flow a standard collet body requires.

Thanks Steve, but I mean gas saver, not gas lens. Or they are the same?

Rgds,
Steph.

Yep.

As far as I know, "gas saver" is a brand name for a gas lens.

If I'm wrong, I'm sure someone will let us know...

Steve

I think they're bit different. You can check them out on www.ckworldwide.com .
Would you tell the cup size you used with 5cfm argon flow, and on what position did you weld that? Anymore, 1/3 means you save 66%. Thats impresive.
I wanna change my regular collet body to gas saver because of that (save 40% gas). By the way, thanks for sharing Steve.

CK's "Gas Savers" are similar to gas lenses and operate on the same principle, with the primary difference being that CK's diffuser is matched to the cup size, where a gas lens is a single size that fits the torch body and will fit various sizes of cups.

I've run 5 CFH (Okay, I got curious and did the math. That's about 30 LPH, or 0.5 LPM, for anyone with a metric flowmeter.) with ceramic cups #5 through #10 on a small 18-series torch. This was in a shop during cool weather where the only air moving was due to exhaust fans high on the wall, so the air was very calm at workbench level.

I have one of CK's sales flyers somewhere; They make some impressive stuff. I do a lot of very restricted access welds where that Pyrex cup would be a blessing, particularly with their micro-torch.

I'd forgotten that was where I saw the thumb control I was going to recommend to a poster on another topic. Thanks for the reminder.

What a good information Steve,thank you for sharing. It's nice to learn from you.

hi Steve, been searching a while and found that 1CFH = 0.472LPM. So your 5CFH = 2.36LPM.
Are you sure tour flow is correct? Isn't it too low? I usually use 7-8LPM on #6-7 nozzles.

Thaks,
Stephanus

I skipped the last step-- I converted 1 CFH to 1 LPM (.47 approx), and forgot to multiply by 5 to get 2.35. Silly me...

Yes, I've welded at 5 CFH, in very calm air.

Steve

Well, that's pretty low mate...I wanna try it sometimes. O yea..on what material you used that flow setting?
Thank you Steve.

304 SS, schedule 5, 3 & 4 inch. I was walking the cup with a very short stick-out.

Steve

Ok, thanks Steve for sharing.
