TLDR
In this article, an arc welding machine is described for providing a continuous feed electrode to a weld site, which includes a line frequency transformer having a primary winding, a first secondary winding, and a second secondary winding (e.g., an extension winding, separate winding, etc.).Abstract:
An arc welding machine is disclosed for providing a continuous feed electrode to a weld site. The arc welding machine includes a line frequency transformer having a primary winding, a first secondary winding, and a second secondary winding (e.g., an extension winding, a separate winding, etc.). The first secondary winding provides a welding power having a first voltage at a welding power output terminal. The second secondary winding provides a second welding power having a second higher voltage at an input terminal of a switch, the switch being controlled to provide a pulsed power at the welding power output terminal. According to one feature, the arc welding machine produces a pulsed power having a fixed pulse width and a fixed frequency, the fixed pulse width and fixed frequency being substantially free of operator adjustment.read more
