Ultra-fine plasma welding from 0.1 mm

EWM Microplasma with three power levels for professional applications

EWM AG offers its Microplasma plasma welding machine for the most delicate welding when working with materials as thin as 0.1 millimetres. This high-tech device for professional users features the latest in digital control technology, cutting-edge inverter technology and compact plasma torches designed for welding work in the finest detail. Areas of application include medical and dental technology, aviation, pneumatic components and welding of various metals to thermocouples.

EWM is offering the Microplasma in three power variants. The current for the plasma arc is adjustable in fine 0.1 ampere steps from 0.3 up to 20, 50 or 100 A, depending on the machine. Plasma technology offers the advantages over TIG welding that the pilot arc is adjustable, affording 100% ignition reliability, and that the plasma arc is extremely constricted, allowing the user to precision-concentrate the water-cooled plasma torch upon the desired point of the workpiece at a temperature of up to 22,000 °C.
