The fully digitised and microprocessor-controlled MIG/MAG power source for short circuit, spray and pulsed arcs enables the best weld properties in every respect, and reproducible time results and time again. The multiprocess power source is suitable for MIG/MAG, TIG and electrode welding, as well as manual or robotic applications. CMT stands for Cold Metal Transfer. The wire movement is incorporated into the process control, where heat is inserted only very briefly.
