Is argon more expensive than CO2?
The most commonly used Inert gas is Argon. Co2 is the lowest cost of the Active Gases, but is far from the best. Co2 produces a cooler, coarser, more spattery arc and a marginally harder weld. Co2 is a more challenging gas to use on thin material and not all Mig Welders perform well with 100\% Co2 as a shielding gas!
How much is CO2 gas for welding?
Welding Gas
| Gas type | Cylinder size | As Low As |
|---|---|---|
| Acetylene | #3 | $55.00 |
| Argon | Q | $38.00 |
| Argon | M | $40.00 |
| Carbon Dioxide | 10 lb | $20.00 |
What is the advantage of using an argon CO2 mix shielding gas?
Benefits of Argon and CO2 mix You can expect a smooth output. The arc will be more stable compared to using pure carbon dioxide. The weld pool will be melted better, allowing deeper penetration. The argon and carbon dioxide mixture will allow just the right amount of heat for material bending and twisting.
What are the benefits of 75\% argon 25\% carbon dioxide gas?
The 75/25 Ar/CO2 is somewhat of a compromise, giving you better weld appearance, reduced splatter, and bead control (helps to keep warpage to a minimum too, from what I was once told). TIG: Oxygen and nitrogen are not your friends here (leading to oxidation & embrittlement).

Is CO2 OK for welding?
Pure CO2 provides very deep weld penetration, which is useful for welding thick material. However, it also produces a less stable arc and more spatter than when it is mixed with other gases. It is also limited to only the short circuit process.

Is CO2 good for MIG welding?
The most common of the reactive gases used in MIG welding is Carbon Dioxide (CO2). Pure CO2 provides very deep weld penetration, which is useful for welding thick material. However, it also produces a less stable arc and more spatter than when it is mixed with other gases.
What is the best gas to use for MIG welding?
argon
A 75/25 argon and CO2 blend is typically considered to be the best overall option for MIG welding, so that’s our top recommendation at Vern Lewis Welding Supply. A “tri-mix” of helium, argon, and CO2 is also sometimes used.
What is the best gas for MIG welding?
What is the cheapest gas for MIG welding?
In MIG welding, carbon dioxide is the most common reactive gas. It’s the only gas you can use in its pure form without adding a noble gas. carbon dioxide is also the cheapest among the shielding gases, making it an appealing choice when material costs are the top priority.
Is argon or CO2 better for welding?
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.
Does argon mix run smoother than straight C02?
I will agree that an argon mix does run a little smoother than straight c02, but I cant say the difference is as immense as some make it out to be. 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.
Should I use 75/25 Ar/CO2 or 100\%?
On mild steels, I’ve seen people use 100\% CO2, but the splatter was terrible – so don’t consider 100\% CO2. The 75/25 Ar/CO2 is somewhat of a compromise, giving you better weld appearance, reduced splatter, and bead control (helps to keep warpage to a minimum too, from what I was once told).
Is 100\% argon OK for MIG welding?
100\% pure Argon would be fine, from a “metallurgical” aspect. Although Argon does yield a somewhat unstable arc (mild steels, etc) – personally, it’s not my first choice for MIG. It’s acceptable – when I’m aware of what the arc is going to do & watch my puddle.
