Coldarc / Coldarc Puls - EWM alpha Q 352 puls MM Operating Instructions Manual

5.16.3 coldArc / coldArc puls

Heat-reduced, low-spatter short arc for welding and brazing of thin metal sheets with low distortion and
for root welding with excellent gap bridging properties.
After selecting the coldArc process (see chapter "Selecting a MIG/MAG welding task") 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
coldArc welding to:
Material
CrNi
AlMg
ALSi
AL99
Steel
coldArc brazing to:
Material
CuSi
CuAl
AlSi
Zn
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 the "Connecting the welding
torch" chapter and the operating instructions for the welding torch.)
This function can only be enabled with the PC300.NET software.
