[TowerTalk] How about wirefeed mig welding

[Mike Nash, ND6A]

Unless there is somethng new that I have not heard of there is no way to
use a mig welder to weld copper. You can howerever weld Mild steel and
aluminum, but not together. As it is virtually impossible to weld to
dissimiliar metals effectively.
Unless I missed somthing in this thread, MIG welding will not work on Copper.
