Unfortunately, depending on how much arcing has occurred, the arc marks or
rough edges left make it even easier to arc again, even with the suppressors.
Suppressors are cheap enough and easy enough to install to give it a try. But,
you may find out that the arcing still occurs. Some people have successfully
deburred the rough edges created from the arcing to get a nice smooth surface
edge again, and the arcing may stop.
Good luck. Bennett ko2ok
