IIn past decades, stick welders did not have much information about gases with regards to welding. This whole concept changed with the invention of TIG and MIG welding machines and their constant rise in usage. Gas is now considered a common commodity in most welding workshops. But how much does welding gas cost? If you’re just setting up shop, you’ve come to the right place. We’ll break down where to get welding gas and the costs associated with it.

Welding gases can be outsourced from various vendors depending on your location and the type of gas you require. Most vendors provide the option of free delivery for local orders and charge a few bucks for regional deliveries.

Welders use welding gases for several reasons, with the main one being shielding the arc from impurities such as dust. Gases are also used to heat metals during welding and to keep the welds clean.

Inert gases are known for not causing any changes to the materials. They also remain in the same state during welding. This ability makes welding more comfortable without weakening or distorting the welds. Reactive gases are the opposite of inert gases. They react by changing their states and causing changes to the materials. This property makes these gases ideal for enhancing the fusion of metals.

What is a CO2 Tank Cylinder?

You might have noticed that most bars and pubs use a CO2 tank cylinder, where the drink is to be served. CO2 tank cylinders are used to pressurize the beer draft system. CO2 tank cylinder which is used for brewing, are mostly made from aluminum. They also come in steel tank is a variety is sizes.

The quality of a CO2 tank cylinder should be really good. It all depends on what type of tank you have because it will surely affect the taste of your drink. Once you get the idea of how to use your cylinder properly, you can easily make new beverages with lots of bubbles, and you can also design plans for your beverages, keeping safety in mind of course.

Well here is the perfect answer to your question. CO2 gas forced into this cylinder, the more it’s forced, and the more inner molecules get close to each other. The molecules inside the cylinder get so close that crowding of gas happens and the movement of the molecules become very slow. When the molecules slow down, they lose heat energy and hence get cold.

When the temperature reaches 880 psi (pounds per square inch), the molecules release enough heat energy to get cold enough to turn into liquid. When these liquids go through some temperature changes, like an increase in temperature, the volume of the liquids expands. In the liquid state, CO2 can be stored in it a lot more than in the gas state. In short, you get to store a huge amount of CO2 in the tank cylinder.

Pressure plays a huge role in this cylinder. It’s all about the pressure; it is the key thing to note. To provide a push for your draft beer system, the pressure has to be nearly 880 psi. Initially, at this pressure, only CO2 is stored inside the tank cylinder, but once you open the lid of the tank, some of the CO2 is released in the form of vapors and turns back to its previous state that is gas. This gas is then allowed to flow into the gas side of your draft beer system.

Unlike growlers, CO2 tanks don’t have a good system of insulation. They have to be handled with a lot of care. A sudden temperature increase can expand the liquid inside it; hence, it can make the tank so hot that it can burn your fingers. So safety measures should be taken properly. This can be done by having a CO2 regulator; the regulator controls the high pressure of the gas to a manageable and prevents the tank from heating up drastically.
