How to Replace the Tip on a MIG Welder

Without a clean, new welding tip the MIG welder you are using will not produce the best welds possible. This is an easy and quick process and should be done on a regular basis to ensure everything on the MIG welder is working properly. Whether you are using flux-core or solid wire with gas, the tips of MIG welders wear out and get clogged with debris and slag. The wire will also smoothly flow out of a clean, new tip.

Difficulty: Easy
