Understanding Mig Welding Inductance

Mig welding is a popular welding process that is used in both industrial and hobby welding applications. It is a reliable, cost-effective way to join two pieces of metal together. However, a key factor in successful mig welding is understanding the role of inductance. In this article, we’ll look at what mig welding inductance is, how it affects the welding process, and how to set it correctly.

What is Mig Welding Inductance?

Mig welding inductance is the relationship between the voltage and current of the weld. It is a measure of the resistance of the welding wire to changes in current. The higher the inductance, the lower the current flow, and the lower the heat generated.

Inductance can also influence the arc stability, arc length, and travel speed. A higher inductance setting reduces the current and can result in a more stable arc. A lower inductance can result in a shorter arc and faster travel speed.

How Does Mig Welding Inductance Affect Welding?

The inductance setting can affect the performance of a mig welding machine. A higher inductance setting can cause the arc to be more stable, but it can also increase the amount of spatter, or droplets of molten metal, which can make the weld look less clean.

A lower inductance setting can result in a shorter arc length and a faster travel speed, but it can also make the arc less stable, resulting in more spatter. It is important to find the correct balance between a stable arc and a clean weld.

How to Set Mig Welding Inductance

The inductance setting is typically located on the welding machine itself or in the welding program. On some machines, the inductance setting may be labeled as “ind.” To set the inductance, you will need to adjust the voltage and current settings.

When setting the inductance, it is important to consider the material you are welding and the type of weld you are making. A thicker material and a deeper weld will require a higher inductance setting. A thinner material and a shallow weld will require a lower inductance setting.

Conclusion

Understanding mig welding inductance is key to successful mig welding. A higher inductance setting can result in a more stable arc, but it can also increase the amount of spatter. A lower inductance setting can result in a shorter arc length and a faster travel speed, but it can also make the arc less stable. It is important to find the right balance between a stable arc and a clean weld. Setting the inductance correctly is essential to the success of your mig welding project.
