Stainless, mild steel, chromalloy. its all 100% argon. the price differance for argon over c25 will never come close to the amount of money youll spend replacing tungsten, gas lenses and cups by running a co2 and argon mix. Now for explaining the gas labels. C25 or sometimes called 225 is 75% argon and 25% co2 C10 or 210 is 90% argon and 10% co2.

Argon pressure Hi blazehaze69, I use 336 cu ft tank and a full tank is about 2500 psi. I stop tig welding when it gets to about 100 psi just to be safe for my welds and also to make sure I bring back the tank with positive pressure to prevent possible contamination for the next fill cycle.

Excessive gas flow will not cause spatter, but it will burn up you wallet a lot faster. For CO2 15-20 cfh, if you are using mix gas or argon for short circuting somewhere between 25-35 cfh is a good starting point. If you want to get into spray transfer you are looking at a range of 45-55 cfh, as the arc is trasfered through the shielding gas only.

Apr 7, 2011 · The manual for the Millermatic 200 does NOT give any info on shielding gas adjustments. All it says is that different gas mixtures have different requirments as far as pressure and flow. This is a good source of info.

Feb 28, 2017 · Obviously welding out of a pickup bed is less desirable that off a flatbed, but I haven't got around to building a flatbed yet. I am trying to organize the space and I'm wondering if I can get input on whether or not an argon bottle can be laid on its side when used or if it has to be upright. I would appreciate any insight on this.

Apr 19, 2011 · The only mix I have ever used in 30+ years TIG welding is Argon/Helium and only once or twice. Other than that it's straight Argon or Helium. I only use Helium on copper welding. For MIG welding there are all kinds of mixes depending on what type of welding you're doing. For general MIG work a 75/25 or 80/20 (which I use) Argon/CO2 mix works best.

May 4, 2010 · The problem with Argon is the arc is tough to start/maintain on steel. CO2 is cheap and puts a lot of heat into the material. But its prone to spatter. The solution has traditionally been to mix the two. The smoothing running argon with the hot running CO2. Many LWS don't stock mixtures other than 75/25 and pure argon and pure CO2 in 80 cu ft ...

I use about 5 cfh, gas lens, #4 cup, 14 to 33 amps average purged at about 2 cfh on the steel tuned exhaust pipes I make. I used 10 to 12 cfh, 48 amps dc #6 cup gas lens, purged at 5 cfh when I was welding stainless tube in the dairies. More gas …

In fact with a smaller machine used only for short arc transfer co2 would work quite fine and would produce better penetration and allow slightly thicker metals to be welded. The one place were an argon mix would hold a significant advantage is on thinner gauge metals since the arc effectively runs cooler than it would with co2.

Argon: 1.78400 (g / l) = 0.111371482 pounds / (cu ft) So 120 cu ft should add 13.36 lbs. And then if you really care (roughly): pressure x volume = some_constant x temperature. The 'some_constant' depends on things like number of molecules. Just be aware that if you double the temperature, you will double the pressure.
