Generally, the following situations:1. The or power supply current is too small: The principle of spot welding is that the short-circuit power supply generates high-temperature molten metal materials for welding. If the power supply current is too small, it will not be able to weld, or the effect will not be At least 100A current is required to weld, if you want to To achieve results, a current of more than 150A is required. You can choose a car starter with peormance (12V 36-50AH), or two 20AH for motorcycles in parallel, or 3 series of lithium batteries for model aircraft, 12V 5000MAH 30C The above lithium Of course. It is not suitable to use too large , more than 50AH , because the current is too large, it may damage the circuit board!2. The wiring is not well conted. Because of the large current, the wiring must be screwed on the with screws, and the contact area should be as large as possible, and the screws and kets should not be separated. It is absolutely impossible to have a effect on the electrode, or screw it on the electrode with a wire! Also, there must be no extension wire. You can't cont the wire yourself, you can't have a contor! Cont the cable directly to the 3. Improper gear setting. There are 10 gears on the board. For those with low discharge current, use a higher gear. Press the button on the board for one gear, and the buzzer will sound, and the 10th gear will sound 10 times The 10th gear has the strongest strength! If you don't work hard when you shift to the 10th gear, it proves that th

• Rated welding current: 100A~200A
