Red tipped 2% thoriated tungsten electrodes are ideal for medium amperage DC welding of non-corroding steels, titanium alloys, nickel alloys and copper alloys using transformer-based constant-current power sources. These electrodes provide good DC arc starts and stability, a medium erosion rate, and have a medium tendency to spit.
