Question

When welding vertical up, you should have:

a. A short arc
b. A long arc
c. The amperage set higher than normal
d. None of the above answers are correct.

Answer 1

For vertical up welding, using a short arc and moderately increased amperage is best for controlling the weld pool and achieving a quality weld.

Step-by-step explanation:

When welding vertical up, it is best practice to have a short arc. This helps to control the weld pool and ensure proper penetration and fusion of the metal. Using a long arc can lead to lack of fusion and excessive spatter, making it harder to produce a quality weld. It is also recommended to use a slightly higher amperage than normal, but this adjustment should be moderate to maintain control over the welding process.
