I work a lot with electronics, especially circuit boards. I often have to remove through components and sometimes desolder with a Hakko soldering iron and the solder pump just doesn't work and the part is very difficult to remove. I decided not to pay much for a cheap dedicated hot air reflow station and try a high temperature heat gun instead. It made a big difference. This heat gun can get so hot that the solder melts and I have to remove the component with tweezers while the solder is still liquid. What a time saver! Too bad I didn't buy it sooner. My only criticism of this unit is that it's hard to tell exactly how hot the air is, there's no temperature reading or even a general idea of the dial. The solder melts at about 370 degrees Fahrenheit and I raised the gun about 3/4 of the way up. I might be a bit hot or cold though TBH.
