What is the purpose of using a MIG welding machine?

The use of a MIG welding machine serves multiple purposes, which is why the selection of all of the options is accurate. One of the primary functions of a MIG (Metal Inert Gas) welding machine is to provide a continuous supply of filler wire. This continuous feed allows for efficient and consistent welding, enhancing productivity and ensuring a strong weld joint.

In addition, MIG welding is suitable for joining various types of metals, including ferrous and non-ferrous metals, making it versatile for different applications. The adaptability of MIG processes also lends itself well to automation, where machines or robots can carry out the welding tasks, thus streamlining production processes in industrial settings.

Therefore, each of these aspects contributes to the overall function of a MIG welding machine, encompassing its ability to join metals, facilitate automation, and maintain a continuous supply of material for welding.
