High-speed, low-heat input, virtually spatter-free welding: Wherever adhesive or solder was used before, CMT (Cold Metal Transfer) welding can be used instead. CMT has revolutionized welding technology and expanded the range of possible applications with its reversing wire movement. The back and forth movement (reversing) of the welding wire—at up to 170 Hertz—produces an exceptionally stable arc. This results in a 33% reduction in heat input and a welding speed almost twice as fast as with conventional dip transfer arc.
