CMT/CMT welding
Process descrip-
tion CMT/CMT
welding
Properties of lead wire electrode (CMT):
- shorter arc than the trail wire electrode
- higher arc power than the trail wire electrode
- starts the welding process
Properties of trail wire electrode (CMT):
- arc tuned to the weld pool
NOTE! Different characteristics are used for each wire electrode in this process
variant.
