Pulling dents from your old hearse or classic car

Step 2 Operation of the stud welder

5. Operation of the stud welder: Once you have a stud inside the stud holder you carefully place the stud welder against the surface you wish to weld the stud to. The copper ring is usually spring loaded, so press firmly. Make sure the contact ring is in contact with the surface, and then press the trigger for NO MORE THAN 4 SECONDS!!! (if you press the trigger to long, you may risk burning a hole thru the metal).
