7. STUD WELDING AND SPOT WELDING
1.) Stud welding
When mounting the stud, the stud must extend past the three support legs about 2mm. Confirm the stud welding position. Press
the support legs on the work piece firmly. Make sure the work piece is smooth and clean. Press the torch trigger. The stud screw
will be welded on the base metal immediately. Check the stud welding strength. If the strength is not sufficient, adjust the torch
pressure, recharge, and repeat the steps. Traditional method such as rivets, lock screws, and common welding typically damages
the base metal. The stud welding process does not damage the base metal.
Using this specific welding function heat will not affect the back side of work piece. The back of the work
piece will have a good appearance.
3.) Stud welding visual test
Please refer to the pictures below for stud welding results. If the stud welding results are unsatisfactory adjust the power, torch
head pressure, or torch head height according to the instructions. ( Note: only adjust one parameter at a time.)
1. Voltage not enough 2. Correct voltage 3. Too high voltage
