DocumentDocumentPMC AC The Fronius solution for optimal gap-bridging ability + Positive cycle - Negative cycle Heat input PMC AC Standard CV Pulse Low High Gap-bridging ability Pulse PMC AC Standard CV Low Very good Material thickness Thin PMC AC Pulse Standard CV Thick PMC AC is a MIG/MAG welding process in which the polarity of the wire electrode is reversed. Optimal for welding thin and ultra-thin sheet metals the PMC AC process enables remarkably low heat input at a constant deposition rate. The special thing about this technology is that the positive & negative phase ratio can be easily adjusted with the help of correction parameters. The result is precise control over the heat input. PMC AC is available on the iWave AC/DC with Multiprocess Pro.
