Can you show some detailed picture of the same.
By giving proper training to the welder will decrease the chances of Arc strikes out side the bevel area.
For welder qualification Arc strikes outside bevel area is considered as a failure to comply with the test.
And in field it s not at all a good practice .
Most of the time Arc strikes occure in the time of restarting so a good restarting practice can reduces the chances of occurance of Arc strikes generally start the weld a quarter inch away from the last tie in long Arc and come back to the tie in then short Arc and weld.

If you are looking for Arc blow resolution then it will be an other topic.

Clamp the welding return cable in the clit which is used for fitup of the weld joint or weld a clit as close as weld bevel and clamp the crocodile clamp on that
