Power Sources are the high-capacity units designed to provide the controlled electrical energy required for Pre-Heating and Post-Weld Heat Treatment (PWHT). These rugged transformers and inverters are engineered to deliver stable, high-current power to ceramic heating pads, ensuring consistent temperature management across multiple zones. This category features portable 6-Way and 12-Way Heat Treatment Units, as well as advanced Induction Power Supplies for rapid, localized heating. Built for the demanding conditions of refineries, power plants, and construction sites, our power sources provide the reliability and safety needed to execute complex thermal cycles while maintaining strict adherence to international welding standards.
