KP4335-047S - Lincoln Electric .047 V-Groove Drive Roll Kit for Solid Steel Wire

Precision V-Groove Drive Rolls for .047" Solid Wire

Achieve superior arc stability and eliminate feeding issues with the Lincoln Electric KP4335-047S Drive Roll Kit. Designed for professional welders who demand precision, this kit is engineered to feed .047-inch (1.2 mm) solid wire with absolute consistency. The drive roll system is the heart of your wire feeder; if the wire isn't moving smoothly, your weld puddle won't be stable. This kit utilizes a specific V-Groove profile, which is critical for feeding hard wires such as mild steel (ER70S-6) and stainless steel (308, 316, etc.). The V-shape wedges the wire into the groove, creating substantial friction for feeding force without crushing the wire or shaving off metal shavings that can clog liners.

Genuine Lincoln Electric components are built to exact tolerances. The KP4335-047S kit ensures that the alignment between the drive rolls and the wire guide is perfect, preventing the wire from wandering or scraping against the feeder housing. This precise alignment is crucial for preventing "bird-nesting"—the tangled mess of wire that occurs when feed restriction causes the wire to buckle before entering the liner. By maintaining a constant feed speed, these rolls help the power source maintain a steady voltage and amperage output, resulting in less spatter, better bead appearance, and deeper penetration.

Key Performance Benefits:

• Optimized Grip: The V-Groove design maximizes surface contact with solid wires, preventing slippage even when the torch cable is bent or twisted.
• Wire Integrity: Unlike knurled rolls that bite into the wire, these smooth V-groove rolls preserve the copper coating on steel wires, reducing flake-off and liner contamination.
• Durability: Made from heat-treated steel, these rolls resist developing a "wear groove" that can lead to inconsistent feeding over time.

For welders operating Lincoln Electric wire feeders, using the correct drive roll size is non-negotiable. Attempting to feed .047" wire with .035" or .045" rolls can result in immediate feeding failures or subtle arc instability that frustrates the operator. This kit provides the exact match for 1.2mm wire, ensuring that your equipment operates exactly as designed. Whether you are working on heavy equipment repair, structural fabrication, or pipe welding, the KP4335-047S delivers the reliability you need to focus on the puddle, not the feeder.
