PAC-MIG developed Endura-Cable to solve problems associated with cable management in robotic welding and to accommodate PAC-MIG’s patented Forced Air-cooled technology. The Endura-Cable uses straight lay copper separated by internal cooling tubes to form a coaxial-like cable assembly that is less flexible than standard coaxial cable utilized by most robotic MIG gun manufacturers.

The standard co-axial cable was designed to be flexible for use in the semi-automatic or hand-held market to address welder comfort and ergonomics. Yet it leads to several problems when used in robotic applications. The rapid motions of the robot cause whipping of the cable, which creates wire feed problems, as well as premature cable failure.

The Endura-Cable’s stabilizing design reduces this whipping effect to increase wire feed ability and prolong cable life. The cooling tubes carry a controlled air flow through the cable hose assembly to the front-end parts, keeping the welding torch cool. This very important feature needs to be understood. Keeping the welding torch cool is the most important aspect of robotic welding productivity. Heat buildup equals downtime. The hotter the robotic torch runs, the less productive it will be. A hot running torch will collect more spatter and particulate on the tip, nozzle, and gas diffuser. This necessitates more cycles to the clean out station and a decreased life of those parts.

The expense of replacing these consumable parts and downtime to change them out more frequently costs companies thousands of dollars per year. PAC-MIG’s patented Forced Air-cooled technology, combined with the patent-pending Endura-Cable design, can save your company thousands of dollars per year and gain an advantage over the competition.
