How To Choose The Best MIG Wire

The quality of welding can come down to the type of wire you choose. In theory, you can join any two metals with a MIG welder. However, the durability and quality of the work you do will depend on the right selection of the electrode (wire). 

Aside from securing better welding results, choosing the right wire also secures improved efficiency. That means you can weld more metals during the same time frame. That is particularly important if you are planning to use your welder often.

There are two types of MIG welding wires you can choose:

Flux-C​​​​ored Wires

If you aren't using shielding gas for your welding operations, your choice should be a flux-cored wire. In most cases, this electrode has silver steel on the outer part and a flux core on the inside. Its task is to keep any contamination from happening while welding and protect the area where you weld. Flux-cored wires are suitable for outdoor use since the wind can’t affect the quality of work. 

You can use these electrodes for materials that are painted, rusty, or dirty. As for the thickness of materials, it is recommended to go up to 18-gauge. While it can provide more heat than solid carbon steel wires, you should be cautious when dealing with thick materials. Some of the metals might require multiple passes before you are satisfied with the quality.

Gas-Shielded W​​​​ires

The alternative to flux-cored electrodes is using gas-shielded wires. There are three choices in this category:

Gas-Shielded Wires

The alternative to flux-cored electrodes is using gas-shielded wires. There are three choices in this category:

  • Carbon-dioxide – CO2 shielding gas is affordable. However, you should be aware that you will get less radiated heat and less attractive beads if you go with this option. Carbon-dioxide electrodes also produce higher fume levels and spatter than other available alternatives. While they secure deep penetration, spray transfer and pulse welding are not an option.

  • Argon-CO2 – the combination of carbon dioxide and argon gas enables low fume levels, but it only delivers shallow penetration. The arc transfer is smooth, and the welder radiates high heat. The beads also look fairly attractive, and you can perform pulse welding and spray transfer.

  • Argon – O2 – this is the most expensive, but also the best option for welding. You will get most heat and the lowest fume levels and spatter with a combination of argon and oxygen. The arc transfer will be smooth, and the penetration rounded.

Another thing to keep in mind is that the material you weld should be the same as the materials of the electrode. For example, if you are welding stainless steel, you will want that type of wire. Hope it’s become easy to choose best welds welding wire.

Welding Wire Size Guide

Another thing to keep in mind is that the material you weld should be the same as the materials of the electrode. For example, if you are welding stainless steel, you will want that type of wire. Hope it’s become easy to choose best MIG Wires now.

You should also consider the size of the electrodes you use. The thickness of the material you are welding determines the wire size you need. 

Gasless Flux-Cored ​​​​Wires

When it comes to flux-cored electrodes, you should go with at least .030” of thickness. With that size, you can choose materials that vary from 20-gauge (.037) up to 14 gauge (.078). If you are planning on welding thicker materials, other alternatives are more suitable. You can use .035” wires for materials from 18-gauge (.050) to 3/16 (.188) of thickness. 

The thickest materials recommended to weld with flux-cored electrodes are of ¼” (.25) thickness. To deal with them, you can use .045 wires. These electrodes can also be used for thinner materials all the way to 16-gauge thickness. However, .045 wires are not appropriate for structures thinner than that. 

MIG Solid Wir​​​​es

As for MIG Solid wires, you can use them on a broad range of materials. Material thickness anywhere from 22-gauge (.031) up to ¼” is suitable for this type. However, you should choose a wire size depending on the size of the material you want to weld. The thinnest wire you should select shouldn’t be below .023”. You can use them for thin materials from 22-gauge (.031) up to 18 gauge (.050). As you can see, the versatility of this wire is not great.

That is why a far better option is using the .030” wire. You can use them for applications from 22-gauge (.031) up to 1/8” (.125). If you don’t plan to deal with thin materials, you can also choose the .035” electrode. They are suitable for thick applications up to 1.4” (.25). However, they should be used for materials thinner than 18-gauge (.050).

Don’t forget to also choose the right amperage. The general rule is that low amperage is suitable for thin materials, while thick applications will require high heat output.
