Lets patent it and cash in when the big two try to use it.
There's two pins on the connector that the foot-pedal shorts out to let the machine know it's a pedal. Make one connector with a simple circuit in front of it that branches out to both the foot pedal and the torch switch. When you press the torch switch, it closes the circuit to turn the welder on, but breaks the circuit that makes it look like a foot pedal. Either that, or you could take over the voltage input from the pedal, and just make it output max voltage when you press the torch switch to get max amps from the machine. Not too complex.
