Abstract: The invention described herein generally pertains to batteries for a welding operation being managed by various staggering techniques. Particularly, various controllers or methodologies can stagger, rotate, or selectively activate and deactivate welding batteries to manage battery parameters or remain within constraints. For example, battery temperature can be monitored and controlled based on staggered charging or derating. In some embodiments, various controls can be integrated with (or methodologies applied to) batteries used in hybrid welders.

Abstract: A wire feeder that can be connected to a variety of power supplies which includes a power conditioner that can detect a current and/or voltage level from a particular power supply and modify the current and/or voltage level when required so as to enable the wire feeder to operate in conjunction with the arc welder when connected thereto.

Abstract: A wire feeder for an electric arc welder comprising feed rolls driven by an electric motor for moving a welding wire toward a workpiece for an arc welding process. The motor is rotated at a speed determined by a WFS signal from a controller when energized by actuation of a start switch, a switch network has a first condition allowing the motor to operate at the speed determined by the WFS signal and a second override condition forcing the motor to rotate at a fixed lower speed, a toggle circuit with a first position to shift the switch network into the second condition upon actuation of the motor start switch and a second position to shift the switch network to the first condition upon receipt of a toggle signal, and a device to create the toggle signal when the load current to the motor exceeds a given value.
