ABSTRACT:
An improved automatic MIG welding torch assembly for use in automated welding environments includes a locking feature to provide an anti-rotational fit between a power adapter and a conductive inner body tube of a welding torch. The conductive inner body tube has a hollow body and a hexagonal shaped external circumference extending along at least a portion of the body tube. An outer tube for use in an automatic MIG welding assembly has a hollow body with at least one end having a polygonal cross-section. A pitch rack is detachably connected to the outer tube with at least two non-threaded fasteners. The outer body tube may also include a smoke exhaust integrally connected to the tube. Improved methods for assembling an automatic MIG welding torch and manufacturing the integral smoke exhaust are also provided.
