Problems solved by technology
[0002] At present, more and more gas-shielded welding is used in industry and household. The wire feeding system of general household gas-shielded welding is inside the machine. Since the diameter of household gas-shielded welding wire is relatively small, basically below 1mm, and the wire feeding system The diameter of the wire feeding hose of the welding machine is also relatively small, and the wire feeding machine is installed inside the welding machine. In the case of poor light, it is difficult to pass the welding wire into the wire feeding hose of the wire feeding machine, and the welding wire and feeding The wire feeding rollers of the wire machine are easily misaligned, which makes it difficult to replace the wire reel when the welding machine is in use, and even the welding machine cannot work normally.

Embodiment approach
[0024] Such as figure 1 As shown, the front panel of the welding machine is lower than the upper shell, and the button 2 is installed on it. When the side door panel 1 is opened, the height of the button 2 is higher than the upper shell. At this time, the two contacts on the button 2 are in the In the disconnected state, the two contacts on the button 2 are respectively connected to pins 3 and 4 of J8 on the front panel circuit board. At this time, the triode Q7 is turned on. Pin 1 of J8 and the cathode of LED are connected to pin 2 of J8. When Q7 is turned on, current flows through the LED, and the LED lights up to illuminate the side chassis.
[0025] When the door panel 1 on the side of the wire feeder is put down, if Figure 4 , the door panel presses the button 2, at this time, the two contacts inside the button 2 are closed, because one of the contacts is connected to the low potential, at this time, one pin of the resistors R53 and R54 is grounded, and the transistor Q...

The invention provides a lighting device of a gas shielded welding machine. The lighting device of the gas shielded welding machine comprises a press button (2), an LED (light-emitting diode) (3) and a switch module, wherein the switch module is connected with a power supply circuit of the LED (3), and the press button (2) comprises a contact A and a contact B. The contact A is separated from the contact B when the press button (2) is in a released state, so that the switch module is switched to a closed state to further turn on the LED (3); the contact A is connected with the contact B when the press button (2) is in a pressed state, so that the switch module is switched into an opened state to further turn off the LED (3). The invention further provides a corresponding welding machine with the lighting device. The lighting device of the gas shielded welding machine uses a door sheet of on the side of a wire feeder of the gas shielded welding machine to achieve automatic turning on and off of the light, thereby facilitating wire replacement and being affordable.
Description
technical field [0001] The invention relates to a welding machine, especially the lighting of a wire feeding system of a gas-shielded welding machine, in particular to a lighting device of a gas-shielded welding machine and a welding machine thereof.
