The temperature of a welding arc is dependent on the voltage, arc length, and ____.
A) filler
B) pressure
C) weight
D) atmosphere

Question

Quizplus · Accepted Answer

The atmosphere plays a significant role in the temperature of a welding arc as it can affect the heat transfer and energy balance of the arc. For example, welding in a vacuum or inert gas environment can result in higher temperatures compared to welding in air due to reduced heat dissipation. Choice A (filler) is not directly related to the arc temperature, while choices B (pressure) and C (weight) have no impact on the temperature of the welding arc.
