WELDING 103 FINAL REVIEW QUESTIONS WITH
VERIFIED ACCURATE ANSWERS 2026
What does constant voltage do? - Answers -requires a specific arc length for a
predetermined WFS
What is constant voltage? - Answers -Voltage stays the same while amperage varies
what affects the arc shape? - Answers -thermal conductivity
Is the shielding gas a factor in the mode of metal transfer? - Answers -yes
If you want to carry more amperage, should you use a smaller electrode or a bigger
one? - Answers -Bigger
why would a magnification lens be helpful? - Answers -so you can see the weld pool
better
