After the single-chip microcomputer detects that the welding pen contacts the nickel sheet, it controls the MOS to turn on, and the entire circuit loop is short-circuited. Since the resistance of the place where the welding pen touches the nickel sheet is much greater than the resistance of other parts of the loop, most of the energy Gathered here, the nickel sheet is melted by heat, and the nickel sheet is welded to the battery.\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003eWelding is a technique that requires practice. Too tight or too loose will result in weak solder joints. If it is too loose, it may burn through the nickel sheet. If the nickel sheet is too tight, the contact resistance is too small, the heat generated is not enough, and the nickel sheet will not be melted. There should not be a lot of sparks when welding, the pits are bright.\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e \u003c\/div\u003e\u003cdiv\u003e\u003cb\u003e\u003cspan style=\"font-size: 18px;\"\u003ePrecautions:\u003c\/span\u003e\u003c\/b\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size: 14px;\"\u003e1.
