you intend to use.

3. Hold the nozzle piece completely perpendicular to and about 1/4 inch off the work piece.
4. Pull the trigger on the torch and release it when it appears that the desired penetration has been
achieved.
5. Make practice spot welds on scrap metal, varying the length of time you hold the trigger, until a
desired spot weld is made.
6. Make spot welds on the actual work piece at desired locations.
