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
