186413 - Miller 186413 Spoolmate Drive Roll .030-.035 V-Knurled

Keep Your Spoolmate Running Smoothly

There is nothing more frustrating than pulling the trigger on your spool gun and feeling the wire stutter or slip. If you are running a Miller Spoolmate and experiencing inconsistent feeding, the culprit is often a worn-out drive roll. The Miller 186413 Drive Roll is the genuine replacement part you need to get back to laying down perfect beads. Designed to fit a massive lineup of guns—including the popular Spoolmate 100, 200, and 3035—this little component plays a huge role in the quality of your weld.

Versatility and Grip
This drive roll isn't just a one-trick pony. It features a dual-groove design that handles the two most common wire sizes for these guns: .030" and .035". Whether you are tackling thin sheet metal or slightly thicker structural work, this single roll has you covered. The V-Knurled texture provides that extra bit of "bite" on the wire, ensuring it pushes through the liner consistently. This is especially helpful in spool guns where the distance from the drive roll to the tip is short but critical.

Easy Maintenance for Better Welds
Over time, the teeth on knurled drive rolls can wear down, or the grooves can become clogged with shavings. Swapping out your old roll for a fresh Miller 186413 is one of the cheapest and easiest maintenance tasks you can perform to instantly improve your machine's performance. A fresh roll means consistent wire speed, which translates to a stable arc and a better-looking weld puddle. Don't let a slipping wire ruin your project; keep a spare drive roll in your kit so you are always ready to weld.

Compatibility You Can Trust
Because this is an OEM part from Miller Electric, you don't have to worry about fitment issues. It drops right into the Spoolmate 100, 150, 185, 200, 250, 3035, 3545, and even the Hobart DP-3545. Stop fighting with your feed and start welding with confidence again.
