What happens if the standoff distance is increased?
A) The arc force is increased because the resistance is higher and the voltage increases.
B) The plasma are will begin to drift sideways due to arc blow.
C) The plasma stream will lose some of its stiffness.
D) Not much until the distance is so great that the arc goes out.

Quizplus · Accepted Answer

Increasing the standoff distance will cause the plasma stream to lose some of its stiffness, meaning it will become less focused and more spread out. This can lead to a decrease in cutting or welding efficiency. Options A and B are not accurate; increasing standoff distance will actually decrease arc force and reduce the likelihood of arc blow. Option D is partially correct but incomplete, as increasing standoff distance can also lead to decreased cutting or welding efficiency before the arc goes out completely.
