What type of electrode is used in MIG welding?

• A. A continuously fed solid wire electrode
• B. A flux-coated rod
• C. A tungsten electrode
• D. A bare copper electrode

Answer: (A)

In MIG welding, the electrode is a continuously fed solid wire that travels through the welding gun and melts to become part of the weld. The wire is fed from a spool, allowing the process to run smoothly and quickly while shielding gas protects the arc and the molten metal. This setup is distinct from other welding methods: a flux-coated rod is used in stick welding, a tungsten electrode is used in TIG welding, and a bare copper electrode isn’t used as the consumable electrode in MIG welding.
