The present disclosure provides a welding system (10) having a welder (12) and a 12V spool gun (14), in which the 12V spool gun (14) includes a 12V motor. The 12V spool gun (14) receives a voltage that is derived from a welding arc voltage, and drives the 12V motor of the 12V spool gun (14) with the derived voltage. The present techniques allow for the use of a spool gun (14) requiring motor power to be used with any ordinary welder.
