I really don't want to spend 1500 bucks or more for a gas mixer and would rather just make something on my own that might work well. The heavier mix of Argon and Co2 allows for better penetration on thicker cuts of steel. MIG welding with argon yields poor and wide penetration. Carbon Dioxide (0.04%) Carbon is the most important element for building molecules essential for living things. pressure setting for Argon/CO2 mix on mig If this is your first visit, be sure to register . 1 0. aston. Most welders refer to this MIG-weld argon mixture as C25 and a lot of companies also produce the gas with this name. Short circuit mig welding can be done using straight co2 , 75/25 argon/co2, 80/20 argon /co2 and a few others. Refillable argon/CO2 cylinder; 20 cu. Flux core only (gas-less mig) is junk unless you don't care about your welds, it is full of porosity and slag. An Argon Regulator should also be used for Argon/Co2 Mixed gases. 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. Relevant identified uses of the substance or mixture and uses advised against Use of the substance/mixture : Industrial … The arc was very stable and controllable and the weld turned out quite neat. CO2 Gas Regulator Co2 Regulator. Lv 4. The additional oxygen also permits higher travel speeds. You’ll receive what is more like an opposite result with a MIG welder. The remaining 0.1 % is made up mostly of carbon dioxide and the inert "rare gases" such as neon, helium, krypton and xenon. All the other Regulators we have discussed have a Male thread to go into a Female Fitting on the cylinder. ft. However, since you are doing GMAW, you may want to look into a two part mix of 98/2 Argon/Co2 This gas mixture is being used more and more for GMAW Spray Transfer and Pulsed Spray with austenitic Stainless steels. the bottle i bought is full and i hate too waste it.

They produce better arc stability and reduce spatter compared to 100% CO2. MaxxiLine 98% Argon 2% Oxygen (Mix) disposable gas bottles are a handy, cost effective alternative to stationary industrial size gas cylinders. So, you can put CO2 in an argon tank, but no argon, or mix into a CO2 tank. 11 years ago. The purpose of the gas in the MIG process is to protect/shield the wire, the arc and the molten weld metal from the atmosphere. Argon-C02 mix gas offers better weldability for thin metals and … If the connection isn’t the one you need, then there are 2 routes available. 80% ARGON 20% CO2 Mix (Compressed) MATERIAL SAFETY DATA SHEET (MSDS Number – MGC P030012) Effective Date: July 2015 1. I probably would not do it, but they use nitrogen for some beers so I guess it would work as long as it could be forced into the liquid. It can also fit into popular brands’ gas holes. Beer gas delivers some of the characteristics of a completely inert gas like nitrogen, and some of the slightly reactive gas, carbon dioxide. Straight co2 welding gas is cheaper than mixed gas. : Ar 7440-37-1 CO2 124-38-9 Most of a Co2 Regulator is the same as an Argon Regulator. This gas is used primarily for small scale production or by hobbyists. Is Argon – Carbon Dioxide Mixture Worth It? Figure 3 MIXED GAS CYLINDER VALVE. Argon tanks (which store highly pressurized gas) need to be able to withstand a much higher pressure than CO2 tanks (which store mostly liquid CO2 in a similar way to an LP tank, but at a much higher pressure than LP), and any argon mix, is also a pressurized gas. 100% CO2 gas was used for the weld on the left. I have noticed the arc created by the welder is extremely loud. I know I use it all the time and it really makes a big difference when tig welding thicker aluminum. This gas, so called because it is used to serve draft beer “on nitro,” is a mixture of nitrogen and carbon dioxide. Your local welding supply is a bit chincy! G Size One Gas 80/20 (Argon/Co2 Mix) 80% Argon, 20% Co2. I would say close to double of the clarke even on comparable settings. Used to shield the weld from contamination, CO2 is plain-old carbon dioxide. Order today! Short-circuit MIG on carbon steel works with almost any combination from 100% CO2 to about 85% argon/15% CO2. A mixture of carbon dioxide and argon gases contains carbon dioxide at a partial pressure of 278 mm Hg and argon at a partial pressure of 588 mm Hg.What is the mole fraction of each gas in the mixture? Figure 4 MIXED GAS NUT & STEM. An Argon/Carbon dioxide mixture used for welding mild, carbon and alloy steels. Stargon SS blend is a carefully controlled blend of argon, carbon dioxide and nitrogen that is designed for joining a … Ever wonder why some welders prefer MIG welding with 100% CO2 shielding gas instead of using a blend of argon and CO2 that’s designed for MIG?. Argon / CO2 welding mix grades 5 , 12, SM , 20 SDS Ref. All Argon Co2 Mix available, Rent Free Gas Cylinders or to Rent. "In contrast to argon - oxy mixes, the argon 2% CO2 mix is very beneficial on multipass stainless welds, welds in which the build up of oxidation elements and slags that can result in weld porosity. In the states, the Yellow Pages telephone directory has a section for "Gas - Industrial & Medical - Cylinder & Bulk." Hes right on this one. Plain Co2 adds some carbon to the joint (not good for some metals). As a welder, I'd be pissed if I couldn't get pure Argon, Helium, Oxygen, Acetylene, Nitrogen, AND CO2 from any supplier (not to mention the common mixes like 75/25 Argon/CO2). The store will … Well it sounds like you know more about it than I do. It was nice and easy to do. The CO2 is much closer in density to argon, and getting a fairly accurate mix becomes simpler. Air is a mixture of gases, consisting primarily of nitrogen (78 %), oxygen (21 %) and the inert gas argon (0.9 %). Argon/CO2 blends are used mainly on carbon and low-alloy steels and have limited application on stainless steels. CHEMICAL PRODUCT AND COMPANY IDENTIFICATION PRODUCT NAME: 80% Argon 20% CO2 Mix CHEMICAL NAME: Argon Carbon Dioxide Mixture FORMULA: Ar/CO2 CAS No. Why test straight co2 gas? The shielding gas cylinder valve has CGA 580 fitting.

When you get some seat time and get really proficient you may find a mix of 50/50 argon/helium to be useful for welding aluminum 1/8" and thicker. I just bought a new welder. MIG Welding requires an Argon-CO2 mixture for higher penetration and heat. Adding an inline filter won't hurt, but moving gasses tend to mix very quickly due to turbulence in the hose, fittings, and torch lead. It is a “yes” if you can think beyond TIG welding. CO2 vs Argon/CO2 Mix (1.5mm steel or thicker) The weld to the right was made using 80% Argon, 20% CO2 shielding gas. Dansensor gas blenders & mixers for CO2, O2, Nitrogen and Argon help achieve the right mixture for MAP packaging for food, beverage and pharmaceuticals. I had a clarke 135 and have just gone to a GYS smartmig 162. The shielding gas mix is comprised of 75% Argon and 25% CO2. I now have a 9 litre hobby cylinder and unfortunately had to get a 5% Co2/Argon mix as they ran out of the 20% Co2/Argon mix. The one BIG difference is the Cylinder Fitting, which is Female. MaxxiLine 98% Argon 2% Oxygen (Mix) disposable gas bottles are Ideal for those situations where you don't use a lot of gas but need to have it for a particular job, or people who dont want to be tied into a gas contract. Stargon CS blend is a precise mixture of argon (Ar), carbon dioxide (CO 2) and oxygen (O 2) and is a universal shielding gas for carbon steel welding applications. If you've got a mix bottle allready you might as well use it though, although if it doesn't cost too much you might want to try the co2 for yourself. Argon Co2 mix is the best. Manufacturer #: SDS. DGreene. X CO2 = X Ar = 100% CO2 is sometimes used for this purpose, but this is a more “old school” approach used for specialty wires – for general MIG welding purposes, 72/25 Argon/CO2 or a tri-mix of CO2, argon, and helium is much more common. Mixed gases can also be used in the spray transfer process that, in turn, provides more visually appealing welds as well as increased productivity. It’s the same stuff used to extinguish fires, carbonate your beer and soda, and keep them cold. Argon is a good shielding agent but … CO 2 helps you with a weld puddle that is … the mix i have is 75% argon and 25% co2. Processes: MIG (Mild and carbon steels) Price includes gas.
