Question

excessive spatter
undercut
underfill
excessive reinforcement
question 24
2 pts
increasing diameter size of your electrode also requires the increase of what variable?
amperage
travel speed
shielding gas
cable size

Explanation:

• For the first question: An arc length that is too long causes excessive spatter. This is because a long arc length leads to unstable arc conditions, and the molten metal droplets are more likely to be ejected as spatter.
• For the second question: When the diameter of the electrode is increased, the amperage needs to be increased. This is because a thicker electrode has a larger cross - sectional area and requires more current (amperage) to achieve the proper melting and welding conditions.

Answer:

• First question: excessive spatter
• Second question: amperage
