What does the "Weld Off Timeout" parameter do?

<P>What exactly does the "Weld Off Timeout" parameter do? It is under arc equipment properties.   Does the system wait the amount of time in this parameter before it generates an error?  The problem I am having is when the robot runs out of welding wire it continues forward until the seam tracking causes it to crash into the part and trigger motion supervision.  I am wondering if I lower this value to some level if it will realize the problem faster and not crash into the part.  Below is what I have from the manual but I need a more specific description.  <FONT size=1 face=Arial><FONT size=1 face=Arial><FONT size=1 face=Arial><FONT size=1 face=Arial></P>
