Arrangements and methods for welding wire payoff sources. A tapered core (150) and base plate (140), optionally along with a wire guide insert (160), are configured with a payout drum package (110) and a cover (120) containing a welding wire stack (130) such that the welding wire may be payed off smoothly from the wire stack (130) during an arc welding operation, without the welding wire flipping or tangling.
