and the rod or ribbon.
5. Once the rod or ribbon begins to melt into the bumper, apply a very slight downward
pressure and begin to work at a backward angle of roughly 45 directing the hot nitrogen
towards where the rod or ribbon meets the bumper.
6. At the end of the tear, use the gun nozzle to melt and tear away the rod or ribbon.
7. Return the gun to its holster and take the soldering iron out.

10. Repeat all steps above on the front side of the tear.
