For large, fine wire conductors, primarily welding cables,
lugs are manufactured with integral crimp blocks as shown in Solder Connections
Figure 9-11. The wire is placed into the lug and a hammer is
used to complete the crimp. These types of lugs are very pop- The basic solder connection should have two elements, a
