K3917-1 - Lincoln Electric Wire Sizer Assembly for 1/16 Inch Wire

Smoother Feeding, Better Welds

As a welder, you know that the quality of your arc depends heavily on how well your wire feeds. Snags, drag, and inconsistent contact can ruin a bead and frustrate even the most experienced operator. The Lincoln Electric K3917-1 Wire Sizer is designed to solve these problems before they reach your torch. Equipped with 0.062 in (1.6 mm) dies, this tool actively sizes and conditions your wire as it leaves the feeder, ensuring it is perfectly round and clean before it enters the liner.

Why use a wire sizer? Even high-quality wire can have slight imperfections or become slightly oval-shaped on the spool. These tiny variances can cause drag in the liner or poor electrical contact at the tip, leading to micro-arcing inside the tip and an unstable arc at the puddle. The K3917-1 shaves or reforms the wire to the exact dimension required, guaranteeing smooth passage and solid electrical contact. This means you get a smoother, more predictable arc, less burn-back, and your contact tips last significantly longer.

Installation is straightforward on compatible Lincoln Electric equipment, allowing you to upgrade your setup quickly. If you are running 1/16" (1.6 mm) wire for heavy fabrication or structural work, this accessory is a game-changer. It takes the variable of wire condition out of the equation, letting you focus on your travel speed and puddle control. Experience fewer jams and more arc-on time with the precision conditioning of the K3917-1.
