Abstract:
A method and apparatus for providing welding type power, including a power and control circuit is disclosed. The power circuit provides welding, control and aux power. The control and aux power are provided with a transformer, and secondary windings for control and aux power are wound on a single bobbin, with a winding separator separating them. Air vents, which can be formed by fins on the bobbin or separator allow cooling of the inner winding.
