Setup Procedure
Selecting Electrode Wire
Several alloy types of filler metals are available, and the best
choice depends on the type of base metals and the desired
characteristics of the weldment, such as ductility and strength,
corrosion resistance, sustained service temperature, and anodic
treatment color matching. In addition, several wire sizes are
available, and the choice here will depend upon several fac-
tors, including base metal thickness and the arc transfer process
used. Consult your local dealer or appropriate AWS publication
for help in selecting an appropriate alloy type and wire size. Also
refer to, "Procedure Settings" later in this chapter, for wire sizes
used with typical base metal thicknesses and procedure set-
tings.
