A. The diameter of the electrode. B. Two to three times the electrode diameter. C. Three to four times the electrode diameter. D. Five times the electrode diameter. E. Six to eight times the electrode diameter. 15. List two methods of striking the arc to begin an SMAW. _ __________________________________________________________________________________________________________________ _________________________________________________________________________________________________________________ 16. _____ How high should a stringer weld bead be above the base metal? A. 1/16 the electrode diameter. B. 1/8 the electrode diameter. C. 1/8 the weld bead width. D. 1/2 the weld bead width. E. Equal to the electrode diameter. 17. What will cause the welding arc to go out or stop? List two causes. _ __________________________________________________________________________________________________________________ _________________________________________________________________________________________________________________ 18. _____ When it is necessary to release an electrode that is stuck to the base metal, which of the following activities is not done? A. Turn the amperage down. B. Keep your arc welding helmet down and release the electrode from the electrode holder. C. Lift your helmet after the electrode is released from the electrode holder and place the electrode holder on an insulated hook. D. Hold the electrode near the base metal and bend it back and forth until it is free of the base metal.
