Abstract:
A plasma cutting system is provided. The system includes a torch tip having a proximal end and a distal end defining a longitudinal axis extending therethrough. The torch tip includes a plasma plenum and a plasma arc exit orifice located at the distal end of the torch tip. The system includes a lead having a distal end configured for connection to the proximal end of the torch tip. The system also includes an atmospheric vent port disposed between the plasma arc exit orifice and the distal end of the lead. The system further includes a conduit fluidly connecting the plasma plenum and the atmospheric vent port.
