300566 - Miller ProHeat 35 Liquid Cooled Cable 160ft CE

Reliable Heat Treatment for Professional Welders

When your job calls for serious preheating or post-weld heat treatment (PWHT), the Miller 300566 Liquid Cooled Heating Cable is the tool you need to get it done right. Designed for the Miller ProHeat 35 system, this 160-foot cable gives you the reach and reliability to handle big jobs without the hassle. Unlike flame heating, which can be inconsistent and dangerous, induction heating with this cable provides deep, uniform heat exactly where you need it. This is crucial for preventing cold cracking in high-strength steels or for meeting strict code requirements on pressure piping.

The "liquid cooled" feature isn't just a fancy spec—it's what lets you run this cable hard for hours without it overheating. If you are doing a long stress-relief cycle on a thick-walled pipe, you need a cable that can handle the current continuously. This cable stays cool enough to handle, thanks to the coolant circulating through it, which also protects the internal copper conductors from burning out. The 160-foot length is a huge plus, giving you plenty of slack to wrap complex joints or reach workpieces that are far from your power source, keeping your workspace clear of unnecessary clutter.

Setting up is straightforward. The cable is flexible enough to wrap easily around pipes, valves, or flat plates, allowing you to create the perfect coil configuration for your specific part. The connectors snap directly into the ProHeat 35 unit, so you aren't fighting with threads or adapters. Whether you are performing a hydrogen bake-out to clean up a weld zone or bringing a heavy casting up to temp, this cable delivers consistent results every time.

Backed by Miller's reputation for durability, this cable is built to survive the shop environment. It resists cuts and abrasion, and because it's CE marked, you know it meets strict safety standards. Stop guessing with rosebuds and torches; upgrade your heat treat game with the efficiency and precision of Miller's liquid-cooled induction technology. It’s the professional choice for welders who care about quality and efficiency.
