Abstract
1363353 Supply circuits for stud welding apparatus HILTI AG 10 Jan 1972 [19 Feb 1971] 1007/72 Heading H2H A supply circuit for stud welding apparatus comprises a battery of condensers 5 which are charged by a transformer 1 via a diode 3, the coupling between the transformer primary and secondary windings being loose. The loose coupling of the transformer windings enables an approximately constant charging current to be supplied to the condensers. Since the initial charging current is low compared with the charging current provided by a conventional transformer a switch 4, which is opened by a control circuit 8 when the voltage across the condensers reaches a pre-set value, may have a low rating. The condensers 5 are connected to welding terminals 7 by a switch 6. The transformer core may have an adjustable air gap and a variable magnetic shunt may be provided between the windings.
