<p>Embodiments of energy storage caddies (20) adapted to couple to a welding power supply are provided. The energy storage caddies (20) may include an energy storage device (36, 36'), a charger, control circuitry (32), and power conversion circuitry (30). Certain control circuitry may be adapted to control the energy storage device to discharge to provide a direct current (DC) voltage output to the welding power supply when a weld load demand is detected, to monitor a charge level of the energy storage device, and to alert a user to an error when the charge level of the energy storage device falls below a predetermined limit.</p> |
