What wire size does this Lincoln contact tip fit?

Contact tips are wire-size specific. Using a tip with the wrong bore diameter causes poor electrical contact, erratic arc, or wire dragging. Match the contact tip to your exact wire diameter.

How often should I replace MIG contact tips?

Replace contact tips when the bore becomes oval, when spatter buildup restricts wire flow, or when you see arc instability and increased spatter. High-current or high-duty-cycle welding requires more frequent changes.

What is the thread size on this contact tip?

Contact tip thread size varies by gun model. Lincoln Magnum and Magnum PRO series use specific thread patterns. Confirm the thread size in the product specifications before ordering.

Are these genuine Lincoln Electric contact tips?

Yes. Lincoln Electric Magnum contact tips are OEM parts engineered for use in Lincoln Magnum and Magnum PRO welding guns. Using genuine parts maintains arc performance and warranty compliance.
