The input power level of my coil was 125VA.
The streamer length was approximately 26 inches.
The streamer made contact on the seam of the can where the aluminum is
connect when it is rolled into a can. The strike appeared to break the weld
which holds the can together.
I used to always keep my spray paint on the concrete floor. Now I keep it in
a wood cabinet.
I have witnessed this twice in my garage, but I have a friend who has had
this happen more often.
