Fronius PMC AC Multiprocess Power Source
The Fronius solution for optimal gap-bridging ability
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.
Overview and features
Application
- Thin and ultra-thin sheet metals
- Specially developed for manually welding extremely thin aluminum or CrNi-steel
Advantages
- Low heat input
- Excellent gap-bridging ability
- Easy arc handling for manual and automated welding
- Gleaming welds due to reduced magnesium oxides (for AlMg wires)
- Lower welding fume emissions
Excellent gap-bridging ability, base material: AlMg3; Filler metal: AlSi5; Sheet thickness: 2 mm; Air gap: 2 mm
Precise adaptation of the heat input to your requirements
AC Power Balance
This correction allows the heat input to be adapted exactly to each specific application.*
+10 An increase in the correction leads to a bigger positive phase ratio and
thus a higher heat input.
0 Default setting
-10 A reduction in the correction leads to a bigger negative phase ratio and thus a lower heat input.
- All welds at the same operating point and thus the same deposition rate.
