74143607 - Arcair Tri-Arc Swivel Cable Assembly, 7 ft

Technical Overview of the Arcair 74-143-607

The Arcair 74-143-607 is a specialized Swivel Cable Assembly engineered explicitly for the Arcair Tri-Arc® series of foundry gouging torches. This component is critical for the operation of air carbon-arc gouging systems, serving as the conduit for both the high-amperage electrical current and the high-pressure compressed air required to melt and blow away molten metal. The assembly measures 7 feet (approximately 2.1 meters) in length, a standard dimension optimized for typical foundry station setups where the operator requires maneuverability without excessive cable slack.

Technically, this cable utilizes a concentric design where the electrical conductor is housed within the air hose. This configuration not only protects the copper conductor from external damage but also utilizes the flow of compressed air to cool the cable during high-duty cycle operations typical in foundries. The defining feature of this part is the "Swivel" connection at the torch end. This mechanical interface allows the torch to rotate independently of the cable, preventing the hose from kinking or twisting during complex maneuvering. This is essential for maintaining consistent airflow and electrical contact. The outer jacket is constructed from durable, heat-resistant materials capable of withstanding the harsh conditions of a foundry, including exposure to hot metal sparks, abrasive surfaces, and industrial contaminants. As an OEM part, it guarantees precise fitment and conductivity specifications for Tri-Arc torches.
