300049 - Miller ProHeat 140ft Liquid Cooled Induction Cable

High-Performance Induction Heating for Industrial Applications

The Miller ProHeat 140 ft. Liquid Cooled Induction Heating Cable (300049) is a critical component designed to maximize the efficiency and capability of your ProHeat 35 induction heating system. Engineered for the rigors of industrial environments, this cable facilitates the transfer of high-frequency energy to the workpiece, generating heat internally within the metal. This method is vastly superior to traditional resistance heating or open flame methods, offering speed, consistency, and safety. The 140-foot length provides exceptional versatility, allowing operators to wrap large diameter pipes or cover extensive surface areas on flat plates without moving the power source.

Advanced Liquid Cooling Technology

Unlike air-cooled alternatives that may struggle under continuous heavy loads, this cable features an integrated liquid cooling path. This design actively removes heat generated by the electrical resistance within the cable itself, ensuring that the cable remains at a safe operating temperature even during prolonged heating cycles at high amperages. This feature is particularly vital for applications such as Post-Weld Heat Treatment (PWHT) and hydrogen bake-out, where temperature stability must be maintained for hours. The liquid cooling also contributes to the longevity of the cable insulation and conductors.

Versatility in Metal Fabrication

This heating cable is indispensable for a wide range of thermal processes. Whether you are performing preheating to prevent cracking in high-strength steels, conducting hydrogen bake-out to avoid embrittlement, or executing stress relieving on welded pressure vessels, the Miller 300049 cable delivers uniform heat distribution. Its flexibility allows it to conform to various geometries, ensuring that the magnetic field coupling is optimized for the specific part being treated. The uniform heating profile helps maintain the metallurgical integrity of the base material and the weld zone.

Seamless Integration and Setup

Designed specifically for the ProHeat 35 Liquid-Cooled Induction System, this cable connects securely and reliably, ensuring optimal system performance. The setup process is straightforward, allowing crews to deploy the heating solution quickly and reduce downtime. The cable is built to withstand the physical demands of job sites, from fabrication shops to field construction projects. Backed by Miller's 3-month warranty, this accessory represents a durable investment in quality thermal processing equipment.
