PMI – 50 TL

Multifunctional device – The ideal solution for welding thin sheets up to ~1mm thick.


The electric arc is constricted by a copper nozzle, which causes a high power density. The concentrated electronic arc can be achieved in conjunction with the controllable plasma gas, higher welding speeds and a deeper penetration, which saves time and money. The tight bundling of the electric arc and the welding speed causes only a narrow heat-effected zone to form, which has a lower thermal distortion in the component result.
