Lay the overlay in overlapping beads and watch the temperature of the part, an overheated piece will distort and crack at the layer boundary. Check the contact tip, a worn bore upsets the wire feed and causes burnback. Match the drive rolls to the wire diameter and check the liner, wire slip shows up at once in an unstable arc. Previously sold as UTP A 73 G3.
