The ProHeat 35


Induction Heating System 

  • Provides a highly versatile tool for preheating, stress relieving, hydrogen bake out, and post weld heat treat in a variety of pipe diameters and even flat plate.

  • In general, shorter cables are used from smaller diameter pipe and are easier to handle and set-up. Longer cables are used for larger diameter pipe or small pressure vessels and tanks.

  • Great for preheat application on geometrics that prevent use of air-cooled blankets.

  • Improved working environment is created during welding. Welders are not exposed to open flame, explosive gases and hot elements associated with fuel gas heating and resistance heating.

  • Easy set-up is achieved using flexible heating cables combined with user-friendly insulation blankets.

Proheat 35 Power Source
The ProHeat 35 induction power source is equipped with a built-in temperature controller allowing for manual or temperature-based programming with an easy-to-learn operator interface.
Output Connector
System Configurations

The ProHeat 35 Induction Power Source is designed with two output connectors for either air-cooled blankets or liquid-cooled cables. This capability requires the use of same size air cooled blankets or in the case of liquid-cooled systems, the applications must be the same (same size pipe, same program and same coil). The Cable Identification System is able to detect which type of cables are attached and configures the maximum output for the power source.
Heating Cables
The heating cable couples the power to the part to be heated. The silicone hose encloses a special copper conductor specifically designed for carrying high-frequency current to maximize efficiency. The hose also carries the
coolant which cools the conducting wire. The hose is reinforced for strength and durability.

Available sizes:
30 ft. (9.1 m)
50 ft. (15.2 m)
80 ft. (24.4 m)
140 ft. (42.7 m)
160 ft. (48.8 m)
Output Extension Cable
The output extension cable connects the liquid-cooled heating cable to the power source. Two quick connect coolant jumpers are included with each cable.

Availbale Sizes:
10 ft. (3 m)
25 ft. (7.6 m)
50 ft. (15.2 m)
75 ft. (22.9 m)
Preheat Insulation w/ Cable Harness
Liquid-cooled heating cable coils of various sizes can be attached directly to this preheat insulation. Once a coil is set up it can easily be moved from part to part reducing setup times. The insulation is 10-foot (3 m) long and can be
cut to length to fit your application. Heating cable not included.
Preheat Cable Cover
Used in preheat applications to protect the heating cable from slag and molten metal created during welding. The 1/2-inch thick preheat insulation must be used with the preheat cable covers.

Available Sizes:
30 ft. (9.1 m)
50 ft. (15.2 m)
80 ft. (24.4 m)
Remote Contactor Control
Remotely start and stop the heating process with this wired rocker switch remote. Includes a 25-foot (7.6 m) cable.
Preheat Insulation
For preheat applications up to 600 degrees Fahrenheit (316°C). Designed to protect the liquid-cooled cable from high temperatures and maintain the optimum coupling distance between the coil and the work. The preheat
insulation is 1/2-inch thick and can be cut to length to fit your application.
RHC-14 Remote Hand Control
Remotely adjust the heat output of the system in manual mode as well as start and stop the heating process.

Available Sizes:
20 ft. (6 m)
100 ft. (30.5 m)
Thermocouple Wire and Connector
Temperature Measurement

Thermocouple wire, 500 ft. (152 m)
Thermocouple connectors (10 pack)
Thermocouple attachment unit (not shown)

Thermocouples welded directly on the part being heated are the most
accurate way of monitoring part temperature for recording and controlling the heating process.
Thermocouple Extension Cable
A simple means of providing thermocouple inputs from the heated part to the power source. The durable cable eliminates the cluttered stringing of individual wires to the work. The terminal connection enables six thermocouples to be used with the system.

Available Sizes:
50 ft. (15.2 m)
75 ft. (30.5 m)
Post Weld Heat Treatment Blanket
Fifty thermal cycles or more per blanket reduces consumable costs compared to other heating methods. Blanket efficiently insulates and optimizes coupling distance between the coil and the workpiece while protecting the liquid-cooled cable. Fully enclosed, sewn blanket eliminates dust for a better work environment.
Digital Recorder
Available in 6 channel & 12 channel
The digital recorder is commonly used in stress relieving and critical preheat applications. The recorder stores temperature data based on time. It is not
required to perform successful heating applications.
Contact Thermocouple Sensor (Probe)
Contact thermocouple sensor installed between the insulation and the part being heated. The contact thermocouple sensor can be used in preheat applications up to 500 degrees Fahrenheit (260°C).
