Miller ProHeat 35 Liquid Cooled Induction Cable 30ft

Flexible Heating Power for the ProHeat 35

When you are tackling a serious preheat or stress relief job on heavy pipe, you need a heating solution that is both powerful and adaptable. The Miller 300045 Liquid Cooled Heating Cable is the workhorse of the ProHeat 35 induction system. At 30 feet long, this cable gives you the freedom to wrap joints on large assemblies, pressure vessels, and structural steel without being tethered too closely to the machine. It is designed to handle the heat so you can focus on the weld.

The "liquid cooled" feature is a game-changer for long jobs. While the pipe gets up to temperature—potentially over 1000 degrees for stress relief—the cable itself stays regulated by the coolant flowing through it. This means you can run the system at higher outputs for longer periods without risking damage to the cable or overheating the setup. It is much faster and more efficient than setting up ceramic resistance mats, and the induction process heats the metal from the inside out, ensuring a deep, uniform soak that inspectors love to see.

Welders and fitters appreciate the flexibility of this cable. It coils easily around pipes, elbows, and valves, allowing you to create a custom heating coil right on the part. The durable outer jacket is built to survive the rough conditions of a fabrication shop or construction site, resisting wear and tear from dragging and handling. The connectors are designed for quick setup and teardown, snapping securely into the ProHeat unit so you can get the heat on and start welding sooner.

Using the Miller 300045 means you aren't just heating metal; you are controlling the thermal cycle with precision. It eliminates the inconsistencies of open flame heating and the hassle of fragile ceramic pads. Whether you are baking out hydrogen or performing a critical PWHT cycle, this cable delivers the consistent magnetic field required to get the job done right. It is an essential tool for any shop running Miller induction equipment.
