EWM welding machines offer a technological advantage in all welding procedures. This is characterised by a high level of efficiency, conservation of resources, and sustainability when welding. Regardless of the welding process – whether you’re looking for MIG/MAG electrodes, plasma, or TIG welding machines – EWM’s range of high-quality, user-friendly welding technology products leaves nothing to be desired.
Welding Machine Types
MIG/MAG welding machines are true all-rounders when it comes to MIG/MAG welding. From non-alloyed and low-alloy steels, CrNi steels and non-ferrous metals, to MIG/MAG pulse or standard welding, and from one-off production to complex production lines, a large number of applications make these welding machines essential in many areas.
TIG welding machines are mainly used for welding clean and safe seams in forced positions and root passes. With EWM’s DC TIG welding machines, you can work with almost any material, from alloyed steel to copper, while EWM’s AC/DC welding machines are the ideal partner for welding aluminium.
MMA welding machines are usually used for dirty materials. Each of EWM’s MMA welding machines is characterised by its excellent robustness and a longer than average service life. Not least, the high mains voltage tolerance and power reserves makes EWM’s MMA welding machines the perfect assistant on the construction or assembly site, and can easily be connected to the generator or the long mains lead for operation
Plasma welding is one of the newest welding procedures. It is a method of tungsten gas shielded arc welding. It involves a concentrated electric arc with a high energy density. The electric arc is created by a water cooled copper nozzle with narrow bore holes, through which the electric arc passes. It has an almost cylindrical shape, and diverges by just a few degrees. This results in a high energy density. The electric arc burns on the needle-like tungsten electrode in the plasma nozzle. It is cleaned using plasma gas.
Indeed, the gas emitted through the small borehole can not provide long-range protection during welding. Shielding gas is therefore supplied through a second nozzle.
