while amperage is set on the machine, what controls voltage during smaw?
arc length
the type of machine being used
welding polarity
material thickness
question 8
2 pts
which polarity produces the deepest penetration with smaw?
dcep
dcen
ac
dcsp

Explanation:

In Shielded Metal Arc Welding (SMAW), arc length controls voltage when amperage is set. Longer arc lengths mean higher voltage and vice - versa. For penetration, DC Electrode Positive (DCEP) provides the deepest penetration as the heat is concentrated on the work - piece.

Answer:

Question 7: arc length
Question 8: DCEP
