摘要

A system (10) is provided that includes a torch power unit (12) that includes a compressor (32) and a controller (94) configured to adjust output of the compressor (32) in response to feedback comprising compressor output, or altitude, or atmospheric pressure, or a combination thereof. A method is provided that includes adjusting operational parameters of a torch power unit (12) to account for environmental conditions affecting performance of the torch power unit (12). A method of manufacturing a portable cutting torch system (12) is also provided. Another system is provided that includes a plasma cutting circuit, a compressor (32), a motor (30) coupled to the compressor, an interface, and an environmental feedback controller (82).
