GAS METAL ARC WELDING SYSTEM FOR A WELDING ROBOTIC ARM

摘要

A gas metal arc welding system for a robotic arm includes a j-arm, a power block, and a bolt. The j-arm has a first end and a second end each having a through hole. The power block has a first opening defining a first passageway along a longitudinal axis and a second opening defining a second passageway substantially along an axis perpendicular to the longitudinal axis. The bolt has a threaded portion configured to extend through the first opening of the j-arm and into the second passageway of the power block, wherein the bolt retains the j-arm to the power block. The threaded portion of the bolt comprises an internal passageway that extends through a longitudinal axis of the bolt, wherein the internal passageway of the bolt and the first and second passageways of the power block are in fluid communication with each other.
