Typical cases for pin welding are i.e. to directly weld a retention wire to a partial for an extension of one tooth, or to position a holder pin for the connecting clamp, if it can’t be fixed to the case otherwise. For pin welding the handpiece is modified in a way that the pin can be shot right onto the case.
The result: pin welding is a very expedient completion of dental welding techniques, which is, at present, not available in any other kind of dental welding apparatus.
