The Goss AP 140M Propane Pressure tool packs a lot of power and is extremely reliable. According to my experience, this tool makes industrial tasks, particularly in metal fabrication, a breeze. The 500,000 BTU output is impressive, and the adjustable flame control ALLOWS for precision work. However, the only downside is that it can be quite heavy and cumbersome to use for extended periods.Overall I highly recommend this tool for any industrial job that requires high heat output..
