What is claimed is: 1. A wire feeder comprising: a hub constructed to support a consumable weld wire; a drive assembly constructed to deliver the consumable weld wire to a weld; a shroud constructed to accommodate positioning of a spool containing the consumable weld wire on the hub; a housing positioned about the hub, the drive assembly, and the shroud; a pressure vessel supported by the shroud and constructed to contain a gas therein; and a valve attached to the pressure vessel and constructed to allow passage of the gas therefrom upon engagement of the pressure vessel with the wire feeder; wherein the shroud has a recess formed therein, the recess constructed to snuggly receive at least one of the pressure vessel and a regulator. 2. The wire feeder of claim 1 further comprising a regulator fluidly connected to the pressure vessel and constructed to regulate the flow of gas therefrom. 3. The wire feeder of claim 2 further comprising a nipple extending from the regulator, the nipple constructed to engage the valve of the pressure vessel and allow the passage of gas therefrom upon connection of the pressure vessel to the regulator. 4. The wire feeder of claim 1 wherein the shroud is positioned adjacent a side panel of the housing and includes a plurality of recesses therein. 5. The wire feeder of claim 1 wherein the wire feeder is incapable of generating a welding power and further comprises a cable constructed to connect the wire feeder to a power source constructed to generate a power suitable for welding applications. 6. The wire feeder of claim 1 further comprising a connector having a passage therethrough, the connector constructed to fluidly connect the wire feeder to a bulk gas cylinder. 7. The wire feeder of claim 6 further comprising a selector valve operatively connecting a flow of gas from at least one of the pressure vessel and the bulk gas cylinder to the wire feeder. 8. The wire feeder of claim 1 wherein the pressure vessel is positioned in at least one of inside the housing, partially within the housing, and external to the housing. 9. A weld wire delivery system comprising: a housing having a cavity formed therein; a consumable weld wire supported in the housing; a drive mechanism constructed to engage the consumable weld wire and deliver the consumable weld wire to a weld; a shroud positioned in the housing and having a recess formed therein; and a regulator positioned in and supported by the recess of the shroud. 10. The weld wire delivery system of claim 9 further comprising a gas container fluidly connected to the regulator and constructed to deliver a weld-grade shielding gas thereto. 11. The weld wire delivery system of claim 9 wherein the shroud has another recess formed therein, the another recess constructed to snuggly receive a gas container therein. 12. The weld wire delivery system of claim 11 further comprising another gas container attached to the weld wire delivery system and external to the housing. 13. The weld wire delivery system of claim 12 further comprising at least one of a valve fluidly connected to at least one of the gas container and the another gas container, the valve constructed to allow an operator to operatively select at least one of the gas container and the another gas container to provide a shielding gas to a weld, and a switch connected to a first valve connected to the gas container and a second valve connected to the another gas container, the switch constructed to allow an operator to remotely operate both the first valve and the second valve. 14. The weld wire delivery system of claim 9 wherein the weld wire delivery system is incapable of generating a welding power and is incorporated into a welding system having a power source remotely connectable to the weld wire delivery system, the power source constructed to generate the welding power suitable for welding applications and communicate the power signal to the weld wire delivery system. 15. The weld wire delivery system of claim 9 further comprising a pressure vessel engageable with the regulator, the regulator having a nipple extending therefrom constructed to operatively engage a valve of the pressure vessel connected thereto. 16. A wire feeder comprising: a suitcase-type housing having a shape to compactly enclose the wire feeder and a cavity formed therein, the cavity constructed to receive a supply of a weld wire therein and the suitcase-type housing having two connected side shells; a feed drive mechanism in fluid communication with the cavity and constructed to remove the weld wire therefrom; first means for providing a shielding gas to a weld, the first providing means originating in the housing; and second means for providing shielding gas to a weld, the second providing means originating outside the housing. 17. The wire feeder of claim 16 wherein at least one of the first providing means and the second providing means is further defined as at least one of a pressure vessel, a gas container, and a gas cylinder. 18. The wire feeder of claim 16 further comprising means for controlling a flow of gas from at least one of the first providing means and the second providing means. 19. The wire feeder of claim 18 wherein the controlling means further includes at least one of a valve, a switch, and a regulator. 20. The wire feeder of claim 16 further comprising a cord extending from the wire feeder to an external power source, the cord constructed to communicate a welding power from the power source to the wire feeder. 21. The wire feeder of claim 16 wherein the housing has another cavity formed therein, the another cavity constructed to receive at least a portion of the first providing means therein. 22. The wire feeder of claim 16 further comprising a strap having a first end pivotally attached to the housing and a second end removeably attachable to the housing such that the first providing means is positioned snuggly between the first and second ends. 23. A wire feeder comprising: a housing having a cavity formed therein, the cavity constructed to receive a supply of a weld wire therein; a feed drive mechanism in fluid communication with the cavity and constructed to remove the weld wire therefrom; first means for providing a shielding gas to a weld, the first providing means originating in the housing; second means for providing shielding gas to a weld, the second providing means originating outside the housing; and a strap having a first end pivotally attached to the housing and a second end removeably attachable to the housing such that the first providing means is positioned snuggly between the first and second ends. 24. A wire feeder comprising: a hub constructed to support a consumable weld wire; a drive assembly constructed to deliver the consumable weld wire to a weld; a shroud constructed to accommodate positioning of a spool containing the consumable weld wire on the hub; a housing positioned about the hub, the drive assembly, and the shroud; a pressure vessel supported by the shroud and constructed to contain a gas therein; a valve attached to the pressure vessel and constructed to allow passage of the gas therefrom upon engagement of the pressure vessel with the wire feeder; a regulator fluidly connected to the pressure vessel and constructed to regulate the flow of gas therefrom; and a nipple extending from the regulator, the nipple constructed to engage the valve of the pressure vessel and allow the passage of gas therefrom upon connection of the pressure vessel to the regulator. 25.
