    So you're saying that the only way it's bad is that it was bad when bottled?...............and the shelf life of argon is ?

      I'm no gas engineer, but I've never heard of argon expiring or going bad. How did you discover it went bad? Does it have a foul odor or something?

        +1...... it is INERT ...... Argon does NOT degrade

          That's how I figure it. Plus being under pressure, it's unlikely to be contaminated after being transferred to that cylinder unless there was already something else in the cylinder or the gas was contaminated to begin with.

            Pretty sure it can't go bad after a year...
            I leased a 300cu/ft bottle of C25 Argon/Co2 in 2013... still using the same bottle with the same original fill. So 4 years later no problems with gas coverage.

              Funny thing is I have a 300 cf and a 150 cf 100% Argon that are owner bottles that I exchange with Air Gas when needed......The rep stops by when I have a welding question...and in this case My old Miller Dial Arc 250 I thought was having an issue as the weld quality just was not normal.........after looking he specifically ask how old was the gas in the bottle I was using.........I mark them with the date I receive them and also the date I change it over to the welder............The large bottle was on the machine and had been there for two years..........he said lets change it over to the newer filled 150 cf bottle..........we did and the welding issue went away.............he also said he never runs a bottle below 250 psi.............and exchanged the 300 cf bottle for free and never sniveled about the cost? ............so I'm not really sure what to make of all that... but he was definitely leaning towards the age of the gas?

                Eeeek....I have a couple of old bottles of gas that I use infrequently, like Tri-mix and pure helium, I hope this is not contagious.

                  Now the reverse of that is I have had Oxygen and Acetylene in bottles for years on the cart with no issue..

                    Exactly, it doesn't. It's an elemental gas (with minor traces of impurities of course).

                    I got the TIG button today for my HTP 221. I should have a chance to use it this weekend.

                      So I was stoked to try this Tig Button out. Everything looked good.....


                      So that green wire has to be grounded to the case of the welder (which should be grounded via case-grounding inside the machine). Well my case is grounded but the screws have sufficient black-oxide coating that I don't feel they will "pick up" what I would consider a good ground.

                      Zinc-plated screws are better, IMO, so I used a screw and a nut to sandwich the ground wire real good. I can't say I'm crazy about how this looks, but it will have to do for now. I know I can easily figure out a way to simply incorporate it in a much more aesthetic way into the welder.




                      That was actually yesterday, but it was much too windy to try it out. I'm still at work as I type this, so if I get home early enough, I hope to try it out! Stay tuned!

                        You're killing me brother. Bring that sap sucker over here and we can do it inside.

                          That is interesting about not running completely empty. I've never heard of that with shielding gases. I've certainly emptied a many oxy/acetylene tanks and never thought twice about it.

                          There is a rule of thumb for scuba tanks to not let me run below a couple hundred psi or some dive shops will charge you because they will have to visually inspect the tanks before the next fill. Something about keeping them with contents prevents moisture from entering the tank. If the tanks get moisture in them, they can rust and then have to be tumbled and then hydro-static tested again. I can see that making sense being underwater, but for welding I'm wondering how it would apply.
                          So I'm wondering what his reasoning is for not using up all the shielding gas?

                            I think it's just to make sure the pressure always stays above atmospheric pressure so no contaminates can possibly get into the bottle.

                              Looks like a good start to some testing!

                              Really the installation that needs the ground wire is just the Miller Syncrowave when running AC on Aluminum with the High Frequency on full time. That machine has a fearsome high frequency and we find it is induced into the TigButton brand amperage control cable by being in close physical proximetry with the torch leads.

                              For most of the inverter type machines, I don't believe it is really necessary. We include that because as of current, most of our customers run Miller Syncrowaves. . How many of those do aluminum welding, I don,t know.

                              Connecting the ground wire does not seem to have any effect upon the control box or the welder at all from extensive testing that we have done.

                              Hopefully you get a chance to give that a good run soon. We are quite hoping that we have gotten it right for that welder!

                                Have you tried FERRITE BEADS on the control cable to knock down some that pesky RFI....???

                                might drop it a few DB ..............
