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 ...

Apr 21, 2011 · 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.

Aug 29, 2010 · 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 …

Feb 1, 2015 · New Dynasty 280DX, bad argon gas solenoid? Don't feel bad. I ran my 350-p for 2-years and was in middle of a cyl when lost 75% of gas flow. Was almost 1/2 day till found small piece crud where hose goes into rear of Michine. In hind sight sounds simple but sure took me awhile to find it.

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.

Mar 9, 2015 · A high pressure Argon flow meter will work with CO2, after all cfm is cfm on any bottled gas. However, a low pressure CO2 meter will not work with high pressure Argon. Because the bottles have different pressures, the bottle outputs are different. Kinda get it now....

Mar 8, 2008 · 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.

I originally went to Air Liquid when I started welding (8 months ago) and they wanted the $80 for 80cf (argon). To make a long story short, after approaching Air Liquid they would not budge on any of their prices. I.E. 5 times more for filler rod, 4.5 times more for gas, $100 more for helmet, 4-5 times for all other accessories.

Jul 25, 2010 · Can our Argon welding gas bottles be stored horizontally? Our new supplier of E size bottles dropped off their first one on Friday. I tried to install over the weekend but quickly discovered that their bottles are 100mm or 4" to tall to fit under my welding bench like the old bottles do. The only way now is to lay it down on the floor.

Aug 20, 2007 · I picked up a tank of straight Helium, to mix with Argon, for 200-250amp aluminum TIG on 1/8" aluminum ramps. Can the setup be as simple as a 2nd regulator, and Teeing the lines together before they go into the welder? A Y may facilitate better mixing. My Sync 250 came with a Smith HM2051A-580 regulator, where can these be purchased seperately?
