Perfection is the principle
rootArc
rootArc puls
Powerful arc for rapid, secure welding
with and without gap in all positions.
rootArc: Short arc with perfect weld modelling ca-
pabilities for effortless gap bridging and positional
welding
rootArc puls: The perfect enhancement for
focused heat input for the higher performance
range
coldArc: Heat-reduced, low-spatter short arc for
high dimensional stability welding and brazing,
plus root welding with excellent gap bridging
capabilities.
coldArc puls: The optimum enhancement for the
higher performance range, with focused heat
input – there where the heat is required.
