Consumable Electrodes
Forms of consumable electrodes
Welding rods (a.k.a. sticks) are 9 to 18 inches and 3/8 inch or less in diameter and must be changed frequently
Weld wire can be continuously fed from spools with long lengths of wire, avoiding frequent interruptions
In both rod and wire forms, electrode is consumed by the arc and added to weld joint as filler metal
