Low-power induction welder EFD Induction will display one of its new low-power induction welders at this year’s Tube Düsseldorf (hall 06, stand C 26). The welders are the latest addition to EFD Induction’s well-known Weldac range of induction welders. “The only differences,” says Peter Runeborg, head of welder sales at EFD Induction, “are the new welders’ lower power ratings of 50-225kW and their smaller footprints. when we did need after-sales support, we received prompt, professional service from EFD Induction.” EFD Induction will de demonstrating one of its compact Minac induction heating systems at Tube Düsseldorf. The smallest Minac weighs only 50kg, but still packs a maximum output power of 10kW.

Even the smallest ‘Twin’ model – which features two fully independent power outputs from one system – weighs a manageable 74kg. The Minac is popular with service companies that want the reliability and speed of induction on-site.

“Everything else – including the high constant power factor of 0.95, the use of rugged IGBT transistors, and our unique five-year warranty on all inverter modules – stays the same.” According to Runeborg, the new low- power Weldacs fill a neglected gap in the tube and pipe market. “These smaller Weldacs are especially attractive to fabricators for whom welding is an important element in a larger manufacturing process. “Such customers need reliable, easy-to- operate and cost-effective welding solutions that can also meet stringent quality and safety standards.” An example of such a manufacturer is automotive component manufacturer Calsonic Kansei, which has chosen one of the low-power welders to weld aluminium components for car radiators and condensers. The new welder has been chosen by Calsonic Kansei UK for its facility in Llanelli, Wales. “Our choice of EFD Induction was in part motivated by our positive experience of a larger Weldac,” says Peter Tomas, production engineer at the Llanelli plant. “The larger Weldac achieved high uptime, and gave us very little trouble.
