Mid Frequency Inverter DC Pneumatic Spot Welding Machine
Main Features
• Three phase AC power input, power balance, high power factory.
• The fast response control of current improves the quality of solder joints.
• For the same welding workpiece, the welding time is short,the power consumption is saved, the welding stability area increased, and the life of electrode is increased.
• It is suitable for welding of metal materials such as aluminum, galvanized steel, high tensile steel and carbon steel, and the welding effect is good.
• It is especially suitable for spot welding and projection welding of plate and plate, plate and projection nut and stud.
• The welding quality is stable, solid, deep penetration and less splash.
• When the unipolar output is controlled, the polarity of the current is constant during the first welding cycle, and the polarity of the two successive welding cycles alternates.
• When AC output is controlled, half wave time is adjustable, and 2-50ms is Programmable.
• Programmable up to 64 sets of welding specifications.
• The three stage heating process is preheating, welding and tempering, and the welding section can be defined by increasing and decreasing stages.
• Programmable pressure control can define 10 Pressure sections at most.
• Programmable output I/O port Programmable 3 segment output, better match with PLC,robot and so on.
• Solder joint count function.
