300045 - Miller ProHeat 35 Liquid Cooled Induction Cable 30ft

High-Performance Liquid Cooled Induction Cable

The Miller 300045 Liquid Cooled Heating Cable is a specialized accessory designed exclusively for the Miller ProHeat 35 Induction Heating System. Engineered for industrial thermal processing applications, this cable serves as the primary conduit for delivering high-frequency magnetic fields to the workpiece. Unlike air-cooled alternatives, this liquid-cooled variant is capable of sustaining higher amperages and longer duty cycles, making it indispensable for demanding Post Weld Heat Treatment (PWHT) and hydrogen bake-out procedures where consistent, elevated temperatures must be maintained for extended periods.

Measuring 30 feet (9.1 meters) in length, the cable offers significant versatility in shop floor and field environments. Its length allows operators to reach weld joints on large vessels or piping systems without needing to reposition the power source constantly. The internal conductors are designed to minimize resistive losses, ensuring that the maximum amount of energy is transferred to the part as heat. The liquid cooling medium circulates through the cable, effectively managing the thermal load generated by the high current, thereby protecting the insulation and ensuring the longevity of the equipment.

Constructed with a rugged, industrial-grade outer sheath, the 300045 cable resists abrasion, cuts, and exposure to typical shop fluids. It is flexible enough to be wrapped into coils of various diameters, accommodating different pipe sizes and component geometries. This flexibility is crucial for induction heating, as the cable must be positioned in close proximity to the workpiece to induce the eddy currents that generate heat. The cable comes equipped with specific connectors that interface seamlessly with the ProHeat 35's cooling and power output ports, ensuring a safe and leak-free connection.

For MRO and fabrication professionals, this cable represents a critical component in achieving code-compliant heat treatments. Whether used for preheating to prevent cracking in high-strength steels or for stress relieving after welding, the Miller 300045 ensures reliable, uniform heating profiles. Its design prioritizes both thermal efficiency and operator safety, maintaining a cooler exterior surface temperature relative to the heated part compared to resistance heating pads.
