Metal Lock Key Butt Welding Machinery , AC pulse Resistance Spot Welder




This machine could choose the function of three times discharging. As for medium carbon steel, this machine possesses the function of preheat and welding anneal and is specially equipped with parallel straight slideway to ensure the parallel pressure of forging power of the welding product so as to achieve smoothness and firmness on the connecting position.


Except for the general functions of AC pulse spot welder, this type of machine also possesses the following features: be able to place the end face of the work pieces on the opposite place. To utilize the contact resistance of the two ends on the connecting position to generate high temperature and high heat to achieve welding effect under the effect of pressure.




1)Adopt Microcomputer controller: It has the functions of parameters analysis, adjustment and control during the welding process of clamping, welding current ,welding time,maintain etc, equipment operation is simple and easy to master.


2)Adopt pneumatic cylinder, veritcal pressure: more clamping force ensure that workpiece is not slippery when it is welded, welding performance is more stable.


3)Good forming: simple process of butt resistance welding, small welding shrinkage and little burrs, it is expedient to simplify back process




Butt welding of wire rod of different size or shape. Also suitable for butt welding of unfolded panel material whose width is within 300mm.
