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 happens until the distance is so great that the arc goes out.

Question

When the standoff distance is increased, the plasma stream loses some of its stiffness. This means that the plasma becomes less focused and may spread out, making it more difficult to control the welding process.
