3. Directions: Please STAND-UP if the statement is TRUE and SIT-DOWN if the statement is FALSE.   QUESTIONS : An electrode consists of a metal core wire. Electrode has an insulating covering (flux-coated). Electrode doesn’t serve as a filler on welding First two digit in Electrode specification serves a welding position. Electrode comes in many colors.

4. Electrode An Electrode consists of a metal core wire with an insulating covering (flux-coated). It is made out of materials with a similar composition to the metal being welded. S.M.A.W
