ABSTRACT:
A multi-function digital pressure measuring device and welding torch having an outlet nozzle with first and second gas inlets with valves. The pressure measuring device having a body with a first gas chamber and a first inlet and a first outlet where the first inlet is connectable to a first gas supply line and the first outlet is connectable to the first gas inlet of the nozzle to permit gas to pass through. The body further having a second gas chamber with a second inlet and a second outlet where the second inlet is connectable to a second different gas supply line and the second outlet is connectable to the second gas inlet of the nozzle to permit gas to pass through. A display attached to the body and a sensor for measuring pressure associated with the first and second gas chamber. A microprocessor connected to the display and sensor, the microprocessor functioning to calculate elapsed time and pressure for display, thereby providing a welder with an accurate preheat indicator of the materials to be welded. The microprocessor can record the length of service of an external component such as a flashback arrestor associated with the torch.
