When inching, (the electrode and drive mechanism are always electrically energized and remain energized several seconds after the gun trigger is released.

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.
