Final answer:
Arc blow is not caused by too long an arc length. The correct statement is that the arc length is directly proportional to the angle of rotation and inversely proportional to the radius of the circular path. False
Step-by-step explanation:
False
Arc blow is a phenomenon that occurs during arc welding, where the arc is deflected from its desired path due to magnetic forces. It is not directly related to the length of the arc. The length of the arc, or arc length, is determined by factors such as the angle of rotation or the radius of the circular path.
The correct statement is that the arc length is directly proportional to the angle of rotation and inversely proportional to the radius of the circular path.
