The Miller ProHeat rolling inductor heating system — now with optional Infrared Temperature Sensor — is a simple and cost-effective heating process that delivers fast, consistent heat and can solve many preheating problems related to moving parts. Released by Miller Electric Mfg. Co., the system is designed to evenly distribute heat into the workpiece, eliminating inconsistencies and quality issues associated with open-flame-torch heating methods.
Temperature measurement now allows operators to set and achieve targeted preheat temperatures easily. The Travel Detection system reduces the potential for hot spots by controlling heating output based on travel speeds and turning off completely if the part is not moving.
Operators can also now monitor the temperature of the part from the power source meters to confirm it is within the required range. In some cases, this can assist operators with documentation.
“The Infrared Temperature Sensor provides peace of mind and validation that necessary temperature levels are met and maintained while reducing inconsistencies and quality issues,” said Joe Ryan, market segment manager for Miller Electric Mfg. Co.
When connected to the Miller ProHeat 35 induction heating power source, this system provides fabrication shops with increased productivity, improved safety and consistency in heating. The rolling inductor heating system greatly improves efficiency versus flame heating because the heat is generated within the part. Direct heat transfer also results in a cooler shop environment and reduced fume levels. Elimination of open flames significantly reduces burn potential and welder fatigue, as well as the need to store explosive gases used for heating.
Compact and portable to configure around various jobs throughout the shop, the system is highly efficient and extremely accurate for increased productivity. Quick time-to-temperature increases production times while reducing consumable costs and labor expenses. This non-contact method of heating also eliminates wrapping cables and allows for continuous fabrication.
