WPC-11 - 8-Inch 3-Jaw Chuck for WP250 Positioner

Technical Overview of the WPC-11 Jaw Chuck

The WPC-11 Jaw Chuck is a specialized accessory engineered for the WP250 Welding Positioner. Designed to facilitate precision rotary welding, this chuck features a robust 3-jaw self-centering mechanism that ensures concentric alignment of cylindrical workpieces. The unit is constructed with a low-profile form factor, which is critical for maintaining the maximum vertical clearance and stability of the positioner's load center.

A key technical feature of the WPC-11 is its reversible jaw system. This design allows operators to configure the chuck for either external (O.D.) or internal (I.D.) gripping without requiring additional tooling. In the external configuration, the chuck accommodates workpieces ranging from 0 inches to 8 inches in diameter. When the jaws are reversed for internal gripping—ideal for flanges or pipe sections—the capacity expands to hold diameters between 3 inches and 11 inches.

Weighing in at approximately 9.09 kg (20 lbs), the chuck provides a solid, durable hold suitable for industrial fabrication environments. The mounting interface is tailored for the WP250 faceplate, ensuring a secure connection that transmits torque effectively during rotation. This chuck is an essential component for shops utilizing the WP250 for automated or manual circumferential welding applications.
