How can the spot welder adjust the voltage and time to secure the wire point? Why is there a yellow circle in the solder joint?
The pneumatic AC spot welder is current regulating. Only with hard norms, will reduce the phenomenon of yellow, energy storage spot welding machine is voltage adjustment, but the mainstream energy storage spot welder is generally uncontrollable. However, under normal circumstances, the welding time can be adjusted to 3 cycles.You should exchange is not possible, spot welding, solder joint is yellow with different welding specification because solder joints thermal contact with air and suitable for different workpiece, if welding is not strong with high welding current or voltage, short time and high current in the exposure time and reduce welding in the air. To completely solve the problem, you need to make a clear description of the welder's parts. This is not a quality problem. Specific adjustment of welding parameters, I will find the best specifications for you, in order to improve production efficiency, in general circumstances, the direction of adjustment is generally not more than 10 times the welding cycle
General spot welding process includes: two aspects of heat generation and diffusion of heat, the size of the heat generated is related to the strength of the welding, as long as the heat is not less than a certain value, strength is guaranteed. The heat of diffusion does not help the strength of the solder joint, but it affects the appearance of the solder joint and the temperature and life of the electrode. The longer the soldering time, the more heat it will spread. Therefore, reducing the welding time and increasing the cooling of the electrode can reduce the discoloration of the solder joint. If the energy storage welder can consider improving the welding pressure and change the electrode shape to improve the appearance of solder joints.
Different welding specifications for different workpieces, in order to improve production efficiency, in general circumstances, the adjustment direction is welding time is generally not more than 10 cycles, if the welding is not stable, increase the welding current or voltage. The pneumatic AC spot welder is current regulating, and the energy storage spot welder is voltage regulating, but the time of the main energy storage spot welder is generally uncontrollable.What you should use is an AC spot welder. The yellow spot is caused by contact between the heat generated at the solder joint and the air. It is impossible to solve the problem completely. Only with a hard standard, a short time, high current to reduce welding in the air blasting time, will reduce the phenomenon of yellow, welding time can be adjusted to 3 cycles. However, in general, this is not a quality problem.To adjust the welding parameters, you need to make a clear description of the welder's parts and I will find the best specifications for you.
