Profile：Features: ? Direct-connected plate structure, special titanium chain transmission, durable ? The preheating system adopts hot air system, and the temperature control adopts PID mode, which simulates but automatically adjusts the voltage phase angle, so that the temperature control precision reaches ±2°C. ? The ideal solder preheating temperature can be achieved. The special structural design makes the temperature drop of the preheating zone and the welding zone <5 °C. ? The spray system is digitally adjusted with a precision control valve for easy management. It also adopts Japanese special nozzle and cylinder moving type (stepping motor type is optional). Three-sided exhaust filter system. Flux automatic pressure supply system. The spray flow can be quickly saturated. The foaming method is an alternative. ? The transport system adopts a segmented structure to effectively prevent deformation of the guide rail. ? The tin furnace is heated by external heat. The materials in the tin furnace are all made of special stainless steel. The temperature control adopts PID mode and analog quantity to automatically adjust the voltage phase angle.
