Böhler Welding’s PP (Push-Pull) marked chucks are designed for the highest precision and reliability in welding wire feeding. This system, which uses synchronized operation of the main feeder in the power source (push) and an additional motor built into the chuck (pull), is crucial when welding sensitive materials or over long distances.

Thanks to the Push-Pull system, the risk of wire jamming, crimping or deformation is minimized, which is especially important when working with aluminum wires, small-diameter wires or core wires of delicate construction. This translates directly into a more stable welding arc, higher weld quality and repeatability, and a significant reduction in production downtime caused by wire feeding problems. This technological solution increases welding efficiency by several percent in applications requiring long wire packages or aluminum welding.

The PP PLUS 401D MIG/MAG chuck has been designed with an advanced liquid cooling system that ensures that optimal operating temperatures are maintained even when welding at maximum current capacity (up to 400A) over long cycles. Precisely designed cooling channels in the torch and neck ensure efficient heat dissipation from the most thermally stressed components, such as the gas nozzle and current tip.

The result is a significant increase in the service life of consumable parts, a reduction in replacement costs, and the ability to conduct uninterrupted work at high parameters. Professionals will appreciate the stability of welding parameters and comfort resulting from efficient cooling, which is crucial in high-volume production and when welding thick materials.
