  • PraxAir proprietary gas question Stargon VS

    I need to renew my bottle leases and happened to see this gas demonstrated at an open house on Friday. I was wondering if any one has experience with StargonVS gas in a 350P machine. Their paper literature has set up parameters for my machine and the weld samples they had looked good but I would still like some real world user input. Thanks, JEFF

    What is the mix ratio?

    Miller tested the 350P and found it to run best on 90/10 Ar/CO2, which is what they recommend to use in the manual. When I talked to them about using alternative mixes, they said that in testing the 350P with various other gas mixes, their second choice is 95/5 Ar/CO2. I asked them about using 92/8 Ar/CO2 and 98/2 Ar/O2 and they didn't recommend those or anything else. I have always mine on 98/2 and it does take some adjusting of the settings to make it run good. Next time I have the bottle filled, I'm going to try 95/5.

      Desert; I think " Stargon VS " by Praxair is - 82% Argon- 10%Helium-8%Co2
      I could be wrong, but that is what I was lead to believe ?

        Stargon CS or Stargon SS

        Good evening everyone,Stargon CS for steel is 90%Argon/8%co2/2%oxygen.Possible typo maybe?For SS Stargon SS is 80%argon/10%co2/10%Nitrogen,Frank

          Frank , Hi; I dunno, there was a thread about this quite a while ago, I just jotted it down. Now that I think about it , it was for Stainless Steel ?
          To be honest I can't remember ? Yes I'm looking at my notes, the other reference was to your first example of Helium 90%- Co2- 8% & O2- 8% ?

          .............. Norm : PS. I hope you are Not as Confused as I am !!!

                OK, Ed; Will Do ! Ed , Prior to 1-1/2 yrs. ago I'd never touched a computer ! Still learnin' how to use this thing ?

                Back to the Gas Blends, Do you think they have enough ??

                  Enough gases?

                  Hey Norm,as if its this is not enough,you can go in there and one time your C-25 will be called Autoweld,the next time it'll be called Stargold etc...

                      Well, the Stargon VS gas from Praxair is definitely:

                      Argon - 82%
                      Carbon Dioxide - 8%
                      Helium - 10%

                      I have used this gas before, and it is great, I have no problems with it. It does run hotter than C-25, so using this on thin stuff isn't as good as a choice as C-25. But this is a multi purpose gas they say, You can run mild steel or stainless with this, and I assume you can use it for Gas-Shielded Flux Core as well. The only reason I did get it, cause sometimes, very rarely I mess with Stainless MIG.

                        Thanks for the response guys, The reps said that they didn't know the actual mix ratio and the gas was hooked to a standard Esab mig machine so I couldn't actually run it as I would on my Miller. The Miller rep did indicate that it will work so based on what you all said and his opinion I will give it a shot. The only thing that worries me is that they change mixes to keep their marketing guys busy! thanks, JEFF

                          Sheesh! I'm glad I don't have to deal with Praxair out here!

                          With Airgas, the most I have to remember is 'Steel Mix' is 85/15, or 84/16, close enough either way. Everything else, they name it by the mix ratio.

                            Jeff renewing your bottle lease shouldn't have anything to do with it. I lease mine from airgas and I lease 5 hi-pressure cylinders. Some are the 200 size and some are 300's. I can trade different sizes of one gas for different sizes of another. Ex: Take in 2 empty 300 sizes argon bottles and exchange for a 50# CO2 and a 200 bottle of argon. I only get charged for the gas because the lease is the same for all ''large'' cylinders.

                            My point is, you should be able to try a bottle of the gas and if you don't like it then, when its empty, exchange it for a bottle of the gas you currently use.

                              Rig, I think that PraxAir will do that. I am changing from one gas company to another so that is the difference I am concerned about before making a switch. Myistar's mix ratio claims definitely confirms the lack of spatter over a wide range of set up conditions. Thanks, JEFF
