Has anyone tried the new Star Gold Aluminium gas????
Picked up one this week( Friday) and will start using Monday morning!!!

Must be some flavor Argon/Helium mix... maybe a dash of Hydrogen for flavor..??

But I could not find it in the Praxair Gas Manual

http://www.prest-o-sales.com/other_links/gases/PDF/ShieldingGases/Manuals/Shielding%20Gas%20Selection%20Manual.pdf

Any more info..??

Could not find it on their website either

New Welding Gas

From what I could find its argon with ppm of o2 and n2o

[USMCPOP]

Final Blend; 200ppm O2/ 200ppm N2O / Argon

From the powerpoint presentation here:

http://awo.aws.org/wp-content/uploads/2014/aluminumconference/14ShieldingGastoImproveCharacteristicsWhenWeldingAluminum_praxair.pdf

The Nitrous Oxide and Oxygen are just to make the welder feel better. Happy Gold gas.

Another Marekting Mix??

Final Blend; 200ppm O2/ 200ppm N2O / Argon

From the powerpoint presentation here:

http://awo.aws.org/wp-content/uploads/2014/aluminumconference/14ShieldingGastoImproveCharacteristicsWhenWeldingAluminum_praxair.pdf

The Nitrous Oxide and Oxygen are just to make the welder feel better. Happy Gold gas.

Went over the presentation and saw no major performance improvement...
actually degraded in some areas...

am I missing something?? or is this a marketing play..??...

is this yet another entry in the welding gas mix bingo??

The addition of the n20 helps calm the anxious welder😌 lol

does not say much there too. hn80 you may be right (again) as the marketing thing.

with some N2O welders might have a smile too (laughing gas)

I think anticosti guide will have to report his experience with it.

Helium is kind of spend these days. I bet this magic mix is even more expensive. Here's some info I've found interesting from Jody and his dad gum good videos on the subject, watch them both if you have time--near the end of the first video is a link to the second video on the top right hand corner of the video window:

http://www.weldingtipsandtricks.com/tig-welding-aluminum-helium-mix.html

I bring this up mainly because its a good video on this, but also because there is some contradictory information in the powerpoint. On pages 11 & 12 of the ppt, they tell us that with helium and argon mixed, there is considerable difference in the width of the weld bead but no significant difference in penetration. In the second of Jody's videos you'll see a significant difference in penetration when he cross sections the weld and etches it. Plus I wonder how width and penetration differ between filler metals and base metal compositions.

Not saying that is the case here... but the industry has made gas mixture and selection a very confusing proposition in the past...
they juggle the gas proportions slightly ...then...give them magical sounding names... and they have the latest miracle to arm the sales staff..

If you want to see how muddy that water is... here is a gas mix cross reference that you might find interesting

The best reference I have found thus far is still the Praxair Gas Selection Manual...

while it does not go into any great depth... it does explain the basic physics of shielding gas behavior...

When I see mixtures in the "parts per million" range, I think contamination more than some mix with a purpose. Is the discussion seriously about "parts per million?" That's almost down to counting the molecules of oxygen and nitrous oxide to be found in your tank of the stuff.

I see an opportunity here to invent a whole line of "ppm" mixes of gases, none of which can be told from the other.

Ed Craig has some rather strong opinions on what he calls "Wonder Mix" gases

A 244cf bottle of N20 cost about $185 to refill, Just FYI.
