An outlet assembly for hybrid pressure and flow regulation includes a first orifice of a first size, a second orifice of a second size that is larger than the first size, and a mechanism that automatically moves the first orifice between a first position, a second position, and a third position. When the first orifice is in the first position, the flow of gas passes through the first orifice, which regulates a flow rate of the flow of gas through the second orifice. When the first orifice is in the second position, the flow of gas primarily bypasses the first orifice and flows through the second orifice with a first specific flow rate. When the first orifice is in the third position, the flow of gas primarily bypasses the first orifice and flows through the second orifice with a second specific flow rate.
A method of determining wear/ degradation levels of a consumable assembly of a welding/plasma torch may utilize a controlled sound signal in order to determine an acoustic profile or full spectral audio analysis dataset of the consumable assembly that facilitate the identification of patterns that correlate to certain wear/degradation levels of the consumable assembly. The full spectral audio analysis dataset may be obtained by subjecting a given consumable assembly to a controlled sound signal between operations and as the consumable assembly degrades over time. The full spectral audio analysis may serve as a wear/degradation profile over the life of the given consumable assembly. With a full dataset known for a particular consumable assembly model, an acoustic profile of another consumable assembly of the same model may be obtained and compared to the full dataset in order to identify the wear/degradation level of the tested consumable assembly.
