Claim:
1. A welding spool gun adapter, consisting essentially of: an adapter housing comprising a top cover and a bottom cover; a welder interface comprising a side of the adapter housing abutting the top and bottom covers, wherein the welder interface is configured to be coupled to a welder; a welding spool gun interface extending through the top cover of the adapter housing; wherein the welding spool gun interface is configured to be coupled to a welding spool gun having a welding wire spool driven by a welding wire spool motor disposed in the welding spool gun; a circuit board enclosed within the adapter housing wherein the circuit board is configured to receive an input voltage via the welder interface from the welder to which the welder interface is coupled and to output an output voltage via the welding spool gun interface to the welding spool gun to which the welding spool gun interface is coupled, wherein the output voltage is different than the input voltage, and wherein the circuit board comprises a control circuit configured to provide controls for the welding spool gun, wherein the control circuit is configured to be powered by the input voltage received from the welder, wherein the controls for the welding spool gun comprise controls for receiving a trigger command from the welding spool gun to which the welding spool gun interface is coupled, and for providing response commands for manipulating the output voltage to drive the welding wire spool motor of the welding spool gun; and a motor speed adjustment knob disposed on the top cover of the adapter housing, wherein the motor speed adjustment knob enables a user to manually adjust a relationship of the input voltage that is received via the welder interface to the output voltage that is output via the welding spool gun interface, wherein the output voltage usable to adjust a speed of the welding wire spool motor of the welding spool gun.
