10 Preparing the Welding Gun
Rotate the stop pin in the chuck so that
– for welding elements up to 20 mm long,
the non-threaded part is in the chuck.
– for welding elements over 20 mm long, the
non-threaded part sticks out of the chuck.
For welding elements with internal threads or chucks for internal th-
readed studs, a special stop pin accessory for internal threads can be
delivered.
Adjust the stop pin so that the overall measurement
value from the top of the lock nut to the bottom of the
welding element is between 50 and 51 mm.
Screw the lock nut back on.
Carefully retighten the chuck on the four fins with pliers
at regular intervals.
This ensures good current conduction. This prevents pre-
mature wear due to spark erosion.
