A wire spool holding and positioning apparatus includes a frame assembly having a plurality of spool location which is movable to place a selected spool location into a presentment position in which the spool will be easily accessible to an operator for removal of wire from the spool. The frame is powered and motion of the frame is controlled by a control circuit that includes a selection device enabling the operator to select a desired spool location to be placed in the presentment position. The control circuit moves the frame assembly until a signal is received from a position-monitoring apparatus indicating that the desired spool location is in the presentment position. When such an indication is received, the control circuit halts the motion of the frame. Preferably, the frame comprises a spoked wheel having spool locations at the outer ends of the spokes. The position-monitoring means includes a series of microswitches selectively engaged by trip bars mounted on the spoked wheel in a pattern such that the position of the spoked wheel is related to which of the microswitches is engaged. The selection device is preferably remote from the frame.
