A controller, a control power circuit, and an auxiliary power module are disposed in the housing. The auxiliary power module/circuit is mounted to the auxiliary power mount. A standard power receptacle is connected to the auxiliary power module. At least one wiring harness connects the welding type power circuit to the auxiliary power module/circuit, which is the only electrical connection between the auxiliary power circuit and the welding type power circuit. The auxiliary power is electrically isolated from the input power and the welding type power. ## Claims ### Claim 1 A welding-type power supply comprising: a housing, including an auxiliary power mount; a welding type power circuit including a bus, wherein the welding type power circuit is disposed within the housing and receives an input; a controller, connected to control the welding type power circuit; a control power circuit, connected to provide control power to the controller; and an auxiliary power module having an auxiliary power circuit, a standard power receptacle electrically connected to the auxiliary power circuit, and at least one wiring harness disposed to be connected to the bus of the welding type power circuit with a plurality of removable connectors, wherein the auxiliary power circuit is mounted to the auxiliary power mount and the only electrical connection between the auxiliary power circuit and the welding type power circuit is through the at least one wiring harness and the plurality of removable connectors. ### Claim 2 (depends on 1) The welding-type power supply of claim 1, wherein the standard power receptacle is a simplex outlet. ### Claim 3 (depends on 1) The welding-type power supply of claim 1, wherein the standard power receptacle is a duplex outlet. ### Claim 4 (depends on 1) The welding-type power supply of claim 1, wherein the standard power receptacle is connected to the auxiliary power circuit using a second wiring harness and a subset of the plurality of removable connectors. ### Claim 5 (depends on 4) The welding-type power supply of claim 4, wherein the at least one wiring harness is two wiring harnesses. ### Claim 6 (depends on 1) The welding-type power supply of claim 1, wherein the at least one wiring harness is removable. ### Claim 7 (depends on 6) The welding-type power supply of claim 6, wherein the auxiliary power module is disposed to be field installed. ### Claim 8 (depends on 1) The welding-type power supply of claim 1, wherein the standard power receptacle is electrically isolated from the input power and the welding type power output. ### Claim 9 (depends on 8) The welding-type power supply of claim 8, wherein the standard power receptacle is electrically isolated from the control power circuit. ### Claim 10 (depends on 1) A method of providing welding-type and auxiliary power using the welding-type power supply of claim 1, comprising: receiving input power; converting the input power to welding type power using said welding type power circuit, and providing the welding type power as an output; providing control power using said control power circuit; providing auxiliary power using said auxiliary power circuit; and electrically isolating the auxiliary power from the input power and the welding type power. ### Claim 11 (depends on 10) The method of claim 10, further comprising, connecting said at least one wiring harness to the auxiliary power circuit and to the welding type power circuit, and connecting a second wiring harness to the auxiliary power circuit and to said standard power receptacle. ### Claim 12 (depends on 11) The method of claim 11, wherein connecting the at least one wiring harness to the auxiliary power circuit and to the welding type power circuit includes connecting two wiring harnesses to the auxiliary power circuit and to the welding type power circuit. ### Claim 13 (depends on 11) The method of claim 11, wherein connecting the at least one wiring harness to the auxiliary power circuit and to the welding type power circuit includes connecting a removable wiring harness. ### Claim 14 (depends on 11) The method of claim 11, wherein connecting the at least one wiring harness to the auxiliary power circuit and to the welding type power circuit is performed in the field. ### Claim 15 (depends on 10) The method of claim 10, further comprising electrically isolating the auxiliary power from the auxiliary power.
