2-4. Stud welding visual test
Please refer to the following pictures, and evaluate the stud welding results.
If the stud welding results are unacceptable refer to Page 6. Adjusting the charge voltage, torch head pressure,
or torch head height may be necessary. (Note: adjust one setting at a time.)
2-5. Stud welding trouble shooting
The following situations may cause unacceptable results. Correct before using the machine.
(1) The earth (ground) cable and the metal are not creating a good connection.
(2) Torch cable or earth (ground) cable is twisted.
(3) The diameter of screw clamp and stud screws are incompatible, or screw clamp is worn.
(4) The base metal is dirty, rusty, painted or other issues interfering with electricity conductibility.
(5) The torch is not suitable for the base metal or stud screws.
(6) The stud screws and the base metal are not creating acceptable connections (Note: the stud screw should
contact the base metal perpendicularly).
(7) The stud welding voltage is not correct.
(8) The capacitor is damaged.
(9) The welding torch must be kept stationary with no movement.
(10) Stud screws are extending too long (or too short) from the stud clamp.
(11) Base metal distortion or movement when welding.
(12) Method for connecting the earth (ground) cable:
1. Voltage not enough
3. Too high voltage
2. Correct voltage
