The Power of Blue .
Easy to install primary power through panel that does not require removal of sheet metal. Multiple output provides two insulated connectors for air-cooled blankets or liquid-cooled cables. Versatile mobility through a lifting eye or optional running gear designed for construction and maintenance. On-board temperature control provides for manual- ortemperature-based programming in a simple-to-learn operator interface. Multiple control thermocouple inputs (patent-pending) are available to control on the hottest TC during heating and coolest TC during cooling for uniform heating and quality. Open output detection (patent-pending) prevents system operation without a covered output receptacle (cable or protective plug). Cable identification system(patent-pending) knows the type of cable attached and limits output to protect cables and blankets.
Isolation fault protection (patented) provides automatic system shut down should power source output short to ground. A sense lead provides direct feedback to the power source to sense fault condition.
Low consumable costs. No fuel costs and minimal insulation costs. Insulation is reusable andmay be used 50 times or more, reducing cost of disposal and replacement. Uniform heating is maintained along and through the heat zone by using induction to heat within the material. The surface of the part is not marred by localized conducted heat at higher than specified temperatures. Time-to-temperature is faster than conventional processes due to the method of applying the heat, reducingheating cycle time. 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. High energy-efficient systems (more than 90% efficient) transfers more energy to the part, decreasing heating times and improving power efficiency (less than 60-amp current draw).

ProHeat 35 Induction Power Source
Built-In Temperature Controller
The ProHeat 35 Induction Power Source is equipped with a built-in temperature controller. The controller provides for Manual Programming or Temperature Based Programming. Manualprogramming provides for setting a power level and a time duration. This is beneficial in preheat applications where a part is heated to temperature and the heating device removed. Temperature Based Programming provides the ability to develop procedures for preheat, hydrogen bake-out or stress relieve. Four control thermocouple inputs and two monitoring thermocouple inputs are provided for heating....
