K3919-1 - Lincoln Electric Wire Sizer Assembly for 2.0mm Wire

Optimize Wire Feeding with the Lincoln K3919-1 Wire Sizer

The Lincoln Electric K3919-1 Wire Sizer is a specialized machine accessory engineered to enhance the performance of industrial wire feeding systems. Designed specifically for welding operations utilizing 0.078 inch (2.0 mm) diameter wire, this unit plays a crucial role in maintaining process consistency and equipment longevity. In heavy-duty welding applications, wire can sometimes develop ovality or minor deformities due to spooling tension or handling. The K3919-1 corrects these imperfections, ensuring the wire that enters the contact tip is perfectly round and dimensionally accurate.

By conditioning the wire, the K3919-1 significantly improves the electrical interface between the consumable and the contact tip. A consistent wire diameter ensures uniform contact pressure, which reduces electrical resistance and minimizes the risk of micro-arcing within the tip bore. This not only stabilizes the welding arc but also drastically reduces the rate of contact tip wear, leading to substantial cost savings in consumables over time. Furthermore, the sizing action helps to strip away minor surface contaminants or shavings that might otherwise clog liners or gun assemblies.

This assembly includes precision dies tailored for 2.0 mm wire, ensuring an exact fit without causing excessive drag on the drive motor. It is an ideal addition for submerged arc welding (SAW) or high-amperage MIG applications where feedability and arc stability are critical critical factors. Robustly constructed to withstand harsh industrial environments, the K3919-1 integrates seamlessly with compatible Lincoln Electric wire feeders, providing a reliable solution for fabricators demanding the highest levels of precision and uptime.
