About ELMA-Tech
ELMA-Tech GmbH, headquartered in Morsbach (Rhein-Sieg district), develops and manufactures welding and coating technology for industry, OEM and trade. The product portfolio includes multifunctional MIG/MAG inverter power sources with pulse and dual-pulse technology, inverter power sources for submerged arc welding and MAG, fully automatic spot welding systems and controls with 10-kHz medium-frequency transformer guns, as well as high-performance inverter power sources for arc wire spraying (LDS) and plasma coating. The range is complemented by body repair tools such as the sheet metal working device MINIspot 3.0 and the mobile pulling tower ELMA-Puller. The systems are used for materials such as aluminium (material classes 5000, 6000, 7000), steel, stainless steel, galvanized sheet and high-strength steels. Reference customers come from the automotive industry (including Opel, Daimler, Audi, BMW), pipeline construction (Berg Steel Pipe Corp) and machine tool manufacturing (Heller). In addition to product sales, ELMA-Tech offers consulting, development, on-site commissioning, maintenance, calibration, repair service and training.
