Understanding the Basics

Before discussing whether you can use flux wire on a standard MIG welder, it’s important to understand the basics of both flux core welding and MIG welding.

Flux core welding is a process that uses a flux-filled wire electrode to shield the weld pool from the surrounding air, preventing oxidation and strengthening the weld. This type of welding is commonly used in outdoor applications and in situations where a shielding gas may not be readily available.

MIG welding, on the other hand, uses a solid wire electrode and a shielding gas to protect the weld pool from contamination. This process is often used in indoor applications and provides cleaner and more precise welds compared to flux core welding.

A standard MIG welder is typically designed to be used with solid wire and a shielding gas. It may have a built-in gas solenoid valve and regulator to control the flow of shielding gas. The wire feed mechanism is also designed to handle solid wire.
