YH-948 II is not only an excellent choice for de-soldering. This compact 4-in-1 machine vastly combines hot air station, desoldering station, soldering station and even a suction pen for flexible uses. The station will preheat for about 5 minutes when turned ON, and beep 3 times when the station is ready. (Pulling the desoldering trigger during preheating will trigger protection code ‘Pht’. the vacuum pump is OFF by default during preheating. So, your 948 desoldering gun won’t clog up due to misuse under insufficient heating.) This function allows the station to heat the internal desoldering mechanism sufficiently to provide better heat transfer and quicker recovery.
