I bought this for freeing parts on my vintage tractor that are rusted solid, so need lots of heat with a certain degree of precision (my 22kw burner way too big). Does the job perfectly and gets nuts cherry red in no time. Does exactly what I wanted it to do so if you are looking for a burner for heating mechanical applications, this is great. It's a lot more heat than go-system hand torch for a comparrison (at least 3x) and very quick. I love my burner ;o)
