Frustrated by erratic wire feeding or constant bird-nesting when welding aluminum? The solution often lies in the condition of your gun's liner. The Miller 197729 Teflon Head Tube Liner is specifically designed to tackle the challenges of feeding soft wires. Unlike steel liners that can drag and deform soft aluminum, this Teflon liner provides a slick, low-friction pathway that allows the wire to glide smoothly right up to the contact tip. This means fewer jams, less downtime, and cleaner, more consistent welds for your projects.
This 2-pack of liners is a must-have for owners of Miller Spoolmatic® 15A or 30A spool guns and XR™-Pistol push-pull guns. These guns are workhorses in the industry, but even the best equipment needs proper maintenance to perform at its peak. The 7.875-inch length is factory-measured to fit perfectly inside the head tube of your gun, eliminating the guesswork of cutting bulk liner material. It supports wire sizes from .023 to .040 inches, making it versatile for various sheet metal and fabrication jobs.
Don't let a worn-out $10 part ruin a day's worth of work. Keeping a fresh head tube liner installed ensures that your expensive spool gun operates exactly as Miller intended. Whether you are in a professional fabrication shop or a serious home garage, using genuine Miller consumables like the 197729 liner guarantees fitment and reliability. Stock up with this convenient twin pack and keep your aluminum welding operations running smoothly.
