Description

Introduction

Maintain a dependable current path between the transformer and welding arm with this flexible laminated copper shunt. Built from multiple copper foils, it combines strong electrical transmission with the movement tolerance required in repetitive resistance-welding operations.

The flexible center section helps accommodate machine vibration and alignment variation, while the hot-pressure-welded end terminals create a secure connection for demanding production cycles. It is suitable for replacement parts, equipment upgrades, and newly designed spot-welding systems.
