Electric welding gun with adjustable electric welding power

“This creation provides a type of welding gun with adjustable welding power. The welding gun is composed of a gun body, heater, solder tube, solder controller, handle, PCB, and voltage regulator controller. Its main feature lies in the installation of a PCB and a voltage regulator controller inside the gun body. The PCB is electrically connected to the voltage regulator controller, and the voltage regulator controller is electrically connected to the heater. By rotating the knob at one end of the voltage regulator controller, the user can infinitely adjust the welding power of the welding gun, thereby enhancing the efficiency of the welding gun.”
