How to solve the phenomenon of continuous welding with the tip of the soldering machine? When using the soldering wire welding of the soldering machine, the phenomenon of continuous welding of the tip may sometimes occur 　　

　　 One, we should understand that the lack of solder joints is related to the tin content, purity and soldering activity of the solder wire, and there is no connection between the difficulty of tin and the tin content.

　　 Second, it is related to the data of the welding position of the automatic soldering machine, whether it is difficult to solder and how the oxidation degree of the data surface affects the dispersion and the tipping condition. It is usually necessary to select different types of solder wires with different flux contents for different data. Only in this way can the dispersion force of the welding wire in the welding process be effectively improved, and the sharpening can be reduced.

　　 Third, it is related to the wattage of the soldering iron, and the temperature required to select the solder wire with different tin content is different. When using low-wattage soldering iron and low-tin content soldering wire, the solder is in a semi-dissolved state due to the poor temperature, which is prone to sharpening. Therefore, it is necessary to choose a suitable soldering iron for soldering.

　　 Fourth, it is related to the flux of the automatic soldering machine. The active agent with strong activity has better dispersibility, strong dehydration ability, and relatively stable electrical function. Therefore, the solder wire with better flux activity can handle continuous soldering.
