0161337076 - ESAB PKB 250/400 Torch Connection Box Assembly

Genuine ESAB Replacement Component

The ESAB Torch Box PKB 250/400 (Part Number: 0161337076) is a critical spare part designed for the maintenance and repair of ESAB welding systems utilizing the PKB series torch configurations. As an Original Equipment Manufacturer (OEM) component, this torch box is engineered to the exact specifications required for seamless integration with compatible wire feeders and power sources. It serves as the primary housing or connection point for the welding torch, ensuring that current transfer, gas flow, and wire feeding operations are conducted without interruption or loss of performance.

In industrial environments, the connection point between the welding gun and the machine is subject to significant mechanical stress and thermal cycling. Over time, housings can crack, threads can wear, or internal seating surfaces can degrade. Replacing the torch box with this genuine ESAB unit restores the structural integrity of the connection, preventing issues such as shielding gas leaks—which can lead to porosity—or unstable electrical contact that causes erratic arcs. The PKB 250 and PKB 400 designations indicate compatibility with systems rated for these amperage classes, ensuring the component can handle the thermal and electrical loads expected during heavy-duty fabrication.

Maintenance personnel and facility managers rely on genuine ESAB parts to minimize downtime and maintain safety standards. This torch box is manufactured from high-quality, impact-resistant materials designed to withstand the rigors of the shop floor. By choosing the correct OEM part, you eliminate the guesswork associated with universal fitments and ensure that your welding equipment continues to meet its original duty cycle and performance ratings.

Technical Application

This component is specifically identified for use with the PKB 250 and PKB 400 series setups. It is essential to verify the equipment parts diagram to confirm that 0161337076 is the correct assembly for your specific wire feeder model. Proper installation of this box ensures correct alignment of the liner and contact pins, which is vital for smooth wire feeding and consistent arc initiation.
