Perfection is the principle

CrNi edge weld of 1 mm sheet metal, with coldArc

coldArc

coldArc puls

Perfect welding and brazing

coldArc: Heat-reduced, low-spatter short arc for high dimensional stability welding and

brazing, plus root welding with excellent gap bridging capabilities.

 Less distortion and reduced discolouration thanks

to minimised heat input

 Considerably reduced spatter thanks to

virtually power-free material transfer

 Impressive process stability even with long hose

packages without additional sensor leads

 Commercial torch systems, as the material is

transferred without drive in the torch,

causing no wear and tear

 Easy welding of the root passes in all

sheet thicknesses and in all positions

 Perfect gap bridging even with

inconsistent gap widths

 Excellent wetting of surfaces when

brazing thin metal sheets

 Minimal finishing work, also optimum for visible

seams

thanks to low-spatter process

 Unalloyed, low-alloy and high-alloy steels and also

dissimilar joints of even the thinnest metal sheets

 Brazing of CrNi sheets with CuAl8/AlBz8

 Brazing and welding of coated metal sheets,

e.g. with CuSi, AlSi and Zn

 Root welding of non-alloyed and low-alloy steels

and high-tensile fine-grained steels

 Visible CrNi seams within the thin metal sheet

range

Minimised heat input -99% less spatter

 Outstanding for butt welds, lap welds and edge

welds

 Perfect for visible seams – no post weld work

necessary

 Ideally suited for high-alloy steels and coated

metal sheets

 Less discolouration and scaling

 Reduced heat-affected zone

 Excellent control for positional welding

coldArc puls: The optimum enhancement for the higher performance range, with focused

heat input – there where the heat is required.
