Abstract
An electronically controlled power supply is adaptable upon throwing a single mode changing switch for shielded metal arc welding (SMAW) and stud welding. The power transformer and control circuitry of a stick welding power supply are, according to the invention, adapted with facility for higher power output, relative to that required for stick welding, for a relatively short timed duration suitable for stud welding. Safety shut down features improve safe use of the power supply, particularly during stud welding, and protect against transformer overload.
