SouthWelds Welding Contact Tip for Miller, .045 2Pk (Hobart 770-183)

SouthWelds Welding Contact Tip for Miller, .045 2Pk (Hobart 770-183)

The SouthWelds Welding Contact Tips for Miller (.045 in., 2-Pack) are precision-machined replacement MIG contact tips designed to provide smooth wire feeding, consistent electrical conductivity, and stable arc performance. Compatible with Miller® M-Series MIG guns and equivalent Hobart® 770-183 applications, these durable copper contact tips are engineered for use with 0.045-inch (1.2 mm) MIG welding wire. Replacing worn contact tips helps maintain weld quality, reduce burnback, and keep wire feeding smoothly—because a tiny worn tip can create surprisingly big welding headaches.
