Feature
01.Three phase AC power input, power balance, high power factor.
02.The rapid response control of current improves the quality of solder joints.
03.For the same welding workpiece, the welding time is short, the power is saved, the welding stability zone is increased, and the electrode life is increased.
04.The welding quality is stable and firm, with large penetration and less spatter.
05.Solder joint counting function.
06.During AC output control, the half wave time is adjustable and 2-50ms is programmable.
07.Programmable multiple sets of welding specifications.
08.Three stage heating process: preheating, welding and tempering, in which the increasing and decreasing sections can be customized in the welding section.
09.Programmable pressure control, 10 pressure segments can be defined.
10.Programmable output I / O port: programmable 3-segment output, which can better adapt to PLC, robot, etc.
11.During unipolar output control, that is, in the process of one welding cycle, the polarity of current remains unchanged, and the polarity of two adjacent welding cycles alternates.
