70128507 - Arcair Tri-Arc K5/K5000 Swivel Cable Assembly, 7 ft, 1250A

Heavy-Duty Power & Air Delivery for Industrial Gouging

The Arcair 70-128-507 Tri-Arc Swivel Cable Assembly is a critical component designed for the rigorous demands of heavy industrial metal removal. Engineered specifically for the K5 and K5000 Angle-Arc® gouging torches, this assembly provides a robust conduit for both high-amperage electrical current and compressed air. With a current rating of 1250 Amps, it is built to withstand the intense heat and electrical loads associated with large-scale fabrication, foundry work, and structural steel processing.

Optimized for Performance and Durability

This 7-foot (2.13 meter) cable assembly features a concentric design where the electrical conductor is encased within the air hose, or vice-versa depending on the specific Tri-Arc configuration, ensuring a streamlined profile that minimizes bulk. The outer jacket is constructed from high-grade, abrasion-resistant materials capable of surviving contact with hot slag, sparks, and rough workshop floors. It requires an air supply of 80 psi (5.5 bar) and a flow rate of 30 cfh to effectively clear molten metal from the gouge path, ensuring clean, consistent cuts.

Ergonomic Swivel Design

A standout feature of this assembly is its 340-degree swivel connector. In heavy gouging applications, manipulating a thick, stiff cable can lead to significant operator fatigue and wrist strain. The swivel mechanism allows the torch to rotate independently of the cable, providing the welder with superior maneuverability and control. This is particularly beneficial when working on complex geometries or in positional gouging scenarios found in marine and offshore structure fabrication.

Industrial Applications

The 70-128-507 is essential for maintaining the operational readiness of gouging equipment in sectors such as:

• Pressure Vessel Manufacturing: For back-gouging welds to sound metal.
• Shipbuilding: Removing temporary attachments and correcting weld defects.
• Foundries: Washing pads and removing risers from castings.
• Hard Facing: Preparing surfaces for wear-resistant overlays.
