Learning how your welding tool operates with a MIG welding gas may be intimidating, especially when you don’t know how to use it. Worry no more because we’re here to share its features in detail. At the same time, we will guide you in terms of choosing the best MIG welding gas products for your tools. Read on to find out more.

What Is a MIG Welding Gas?

A metal inert gas (MIG) welding tool often uses a shielding gas for MIG and a solid wire electrode for clean and slag-free welding. Since the 1920s, welders have been using shielding gases to protect both their work and themselves. At the start of World War II, using these gases had been a niche practice. But in the succeeding years, they have become an industry standard.

If you don’t know what a shielding gas is, it is a welding accessory that prevents the molten weld pool from exposure to a variety of gases in the atmosphere, such as oxygen, nitrogen, and hydrogen.

Should these elements be in contact with each other, the reaction will lead to numerous problems such as an excessive release of spatter, porosity, and hole formation within the weld bead.

Kinds of MIG Gas

Despite several guides that show how simple it is to use MIG gases, many welders are still intimidated by it. The most common question is what type of gas they should be using and how to mix them to yield more options.

You must be aware of your shielding gas’s functions, especially because it is crucial in your welding activity. Let’s have a closer look at their purposes.

  • Clearing the arc of impurities, including dirt, dust, and other gases
  • Improving arc stability and ensuring proper metal transfer
  • Ensuring that the welding pool remains clean and below the seam (purging) for blanketing and heating

In terms of the kinds of gases, there are two main types: inert and reactive gases.

  1. Inert gases: Chemists define this as a “non-reactive gas under a certain set of circumstances or conditions.” The inert gases include noble gases or pure elements. They are not limited to those, however, because sometimes gas can still be inert even as a compound.
  2. Reactive gases: As the name implies, reactive gases react physically and chemically when in contact with other elements or compounds. We usually observe these reactive gases during the cutting or joining process of metallic scraps and surfaces.

Gas Selection

Because there are multiple MIG welding applications, there is also a variety of choices for gas. You can even perform MIG welding without gas.

When choosing a gas for a particular welding application, there are a few things you need to consider to meet your welding goals.

  • The base material’s properties
  • The cost of the gas type
  • The finished properties
  • The mode of transfer
  • The preparation and cleanup

Although new gases are under development to accommodate emerging metals and welding needs, the most commonly used gases are still carbon dioxide, argon, oxygen, and helium.

Below are two essential points regarding gas selection.

  1. A gas mixture with 25–75% argon has an excellent effect on your shielding gas. Using gases with this component will leave a clean look on your workpiece.
  2. Carbon dioxide is the most economical choice if you are short on cash or if you need a readily available source from your nearest welding essentials store. Compared to argon, carbon dioxide has a firmer and deeper welding power.

The MIG Gun

Considering the above factors, welders choose a MIG gun for its ability to create successful MIG welds. Before we head over to its features, here are some things you need to know about preparing your MIG tool for the welding activity.

  1. Take a look at the cables. Check if your cables are tight-fitting and free of any damage. Then, monitor your MIG welding gas setting to know if your equipment is ready to use.
  • Choose the electrode polarity. Not all welding tools have the same electrode polarity. For MIG welding, you will need a DC electrode positive or reverse polarity. You can find your tool’s polarity connections inside the machine.
  • Set a gas flow for your tool. You can adjust the shielding gas for your MIG tool to a flow rate of 20 to 25 cubic feet per hour. Should you be concerned about leaks in your gas hose, you may apply a soapy water solution to your gas hose and search for bubbles. If you find a leak, discard your hose and replace it with a new one.
  • Check your welding tool’s pressure. Whether your tool has too much or too little pressure, you’ll need to change it. The key to getting the right MIG welding gas pressure is by following the manufacturer’s manual.
  • Inspect its consumables. As you examine your welding equipment, you might notice spatter form after being in contact with tubes. You’ll need to remove this, as well as the rusty wires, and replace the contact tips and liners. Once done, you’re ready to start welding.
