KP2529-2 - Lincoln Electric KP2529-2 .035 V-Groove Drive Roll for Power MIG 140/180

Precision Wire Feeding for Lincoln Power MIG Welders

The Lincoln Electric KP2529-2 Drive Roll is a critical component designed to maintain the optimal performance of your Lincoln MIG welding equipment. Engineered specifically for use with .035-inch (0.9 mm) solid welding wires, this drive roll features a precision-machined V-groove geometry. This smooth groove design is essential for gripping solid mild steel and stainless steel wires effectively without deforming the wire surface or causing shaving, which can lead to liner clogs and erratic arc characteristics.

Maintaining the integrity of your wire feed system is paramount for achieving high-quality welds. A worn drive roll can cause wire slippage, irregular feed speeds, and the frustrating "burn-back" phenomenon where the wire fuses to the contact tip. By replacing your worn components with this genuine Lincoln Electric OEM part, you ensure that your machine operates within its factory specifications. The KP2529-2 is manufactured to exact tolerances, ensuring perfect alignment with the wire guide and liner of compatible machines.

This drive roll is specifically compatible with the compact Lincoln Electric Power MIG series, including the Power MIG 140C, Power MIG 180C, and the Power MIG 180 Dual. It is not intended for use with flux-cored wires, which typically require a knurled drive roll to bite into the softer, tubular wire structure. For solid wire applications, however, the smooth V-groove of the KP2529-2 provides the necessary traction while preserving the wire's copper coating and structural integrity.

Installation is straightforward and requires no specialized tools, allowing operators to switch between wire sizes or replace worn rolls quickly during maintenance intervals. Whether you are fabricating in a professional shop or performing automotive repairs in a garage, relying on genuine Lincoln Electric consumables like the KP2529-2 ensures consistent delivery of filler metal to the weld pool, resulting in cleaner beads and less downtime.
