tom, arc blow is a magnet phennomenum that can happen occasionally when doing welding with a DC welder as the poles do not alternate when actually welding. The 3 counter measures are in order of simplicity:
1. move the ground to a different location.
2. change the direction of travel.
3. wrap the ground cable around the item several times.
