186414 - Miller Spoolmate Drive Roll .030/.035 Wire

Keep Your Spoolmate Running Smoothly

Don't let a slipping wire ruin your weld or slow down your production. The Miller 186414 Push Roll is the exact replacement part you need for your Spoolmate spool gun to ensure reliable wire delivery. Designed to handle the two most common wire sizes used in light industrial and hobbyist applications—.030 inch and .035 inch—this drive roll is the heartbeat of your wire feeding system. When you are welding aluminum, consistent feed speed is everything; a worn drive roll can cause stuttering, burnback, and poor weld quality.

This push roll is built for versatility and broad compatibility. If you own a Millermatic welder equipped with a Spoolmate 100, 185, or 200, or if you are using the Spoolmate 3035 or 3545 on a larger machine, this is the correct part for your setup. It is also compatible with the Hobart DP-3545. The installation process is straightforward, meaning you can get back to welding in minutes. Keeping a spare push roll in your toolbox is a smart move for any welder who relies on their spool gun for daily tasks.

Genuine Miller parts like the 186414 are crafted to withstand the rigors of the welding environment. Unlike generic aftermarket replacements that might have slight size variations, this OEM roll guarantees proper alignment with your wire guides and inlet. This precise fitment reduces friction and wear on the wire itself, preventing shavings from clogging your liner. Whether you are a DIY enthusiast working on a weekend project or a professional fabricator, using the correct drive roll is the first step toward a perfect weld.

Stop fighting with your wire feed and start welding with confidence. Replace your old, worn-out roller with a brand new Miller 186414 Push Roll and experience the difference in arc stability and control. This package includes one replacement roll ready for immediate use.
