Important! Press and release the torch trigger again to interrupt spot welding.
The settings have been correctly selected if the upper side of the spot displays slight
swelling, and it is visible on the underside of the spot-welded sections that they have
been welded through. In addition, ensure that the items to be spot-welded are complete-
ly flush, one on top of the other, and that there is no risk of impurities (varnish, rust).
Warning! Operating the equipment incorrectly can cause serious injury and
damage. Do not use the functions described here until you have read and
completely understood all of the following documents:
- these Operating Instructions
- all operating instructions for the system components, especially the "Safety
rules"
Note! For spot welding, the welding torch must be equipped with the spot
welding attachment.
