Kuhtreiber KITin 270 MMA


5-250 A

Three-phase portable digital inverters for welding by MMA method.

Portable welding machines KITin 270 MMA are designed as small, light and powerful digital threephase inverters.
Digital controls ensure not only optimal settings of the welding characteristics, but their dynamic adaptation during the welding process as well. In this way there is achieved a substantially higher quality of weld joint and simplification of welding process. A significant benefit is achieved in new functions, which help to keep the welding arc in an optimal working characteristics. Due to this arc control technology excellent results may be achieved even by less experienced welders.
Digital and progressive hardware design enabled reduction in weight, dimensions and consequently also in price of the this inverters. The construction of the performance part itself is excessive to ensure reliability, high performance and high duty cycle.
