I was informed that a welding gun should not be used when welding and desoldering sensitive circuits such as those that use FETs, as they can be damaged. It is true?"
Although the welding guns are comfortable due to their ease of use, as they heat up instantly, there is a problem associated with the fact that the tip is heated by passing a current. Thus, the pistol tips are energized, with a voltage that can be dangerous for sensitive components such as integrated circuits, FETs, etc. Thus, a recommendation is to avoid working with these guns on sensitive circuits.
