Systems and methods relating to securing a torch assembly and a work lead assembly to a plasma cutting power supply are provided. The present disclosure relates to a system and method that allows the torch assembly and the work lead assembly to be readily replaced by the user since the power supply unit need not be opened or disassembled for removal. The present disclosure provides methods and systems for removably securing both the torch assembly and the work lead assembly to the plasma cutting power supply. In one embodiment, the torch assembly and the work lead assembly may be communicatively coupled to the plasma cutting power supply unit via a single cable and a single connector. The connection between the first connector and the first port may be of the quick disconnectable type. The connection between the second connector and the second port may be of the twist lock type, such as a dinse style connector.
