Correct Contact Tip Recess Can Improve Welding …

Because less wire stickout typically results in a more stable arc and better low-voltage penetration, the best wire stickout length is generally the shortest one allowable for the appliion. In a MIG welding process, the contact tip is responsible for transferring the welding current to the wire as it passes through the bore, creating the arc.
