5.3.6.4 coldArc / coldArc puls
Heat-reduced, low-spatter short arc for high dimensional stability welding and brazing, plus root welding
with excellent gap bridging capabilities.
Figure 5-25
After selecting the coldArc process
> see 5.3.5 chapter
the following properties are available:
• Less distortion and reduced discolouration thanks to minimised heat input
• Considerably reduced spatter thanks to virtually power-free material transfer
• Easy welding of root passes in all panel thicknesses and in all positions
• Perfect gap bridging even with inconsistent gap widths
• 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
• Manual and automated applications

You can make use of these properties after selecting the coldArc process (see the "Selecting a MIG/MAG
welding task" chapter).
With coldArc welding, it is important to ensure good quality wire feeding because of the welding filler
materials being used!
• Equip the welding torch and torch hose package to suit the task! (
> see 5.3.1 chapter
and the
operating instructions for the welding torch.)
This function can only be enabled with the PC300.NET software.
(See operating instructions for the software)
