Carbon-Electrode Pneumatic Spot Welding Machine Silver Contacts / Points

Silver Contacts / Points Pneumatic Carbon-Electrode Spot Welding Machine


This machine adopt carbon electrode design to weld silver point.

Pneumatic AC pulse spot welder utilizes the general mains supply to lower the voltage and increase the electric current. Such kind of low voltage but large current will be transmitted from the electrode to the linked point of two work pieces. On the linkage, due to the resistance of work piece, high temperature will occur so the metal will therefore generates high heat to make the work pieces in molten condition. Thus, the purpose of welding the two work pieces is achieved. It can be used to weld 10mm of iron and metals like stainless steel. Applicable to all kinds of hardware. Powerful and strong welding current and precise current control. In order to welding different thickness of products, conduction angle of silicon controlled rectifier is divided into 1000 parts for asjusting. Using digital integrated circuit control, strong anti-interference ability, stable and reliable work. Control circuit calls the built-in voltage fluctuation compensation circuit, which can guarantee the power supply fluctuation within + 15% range in a timely manner to make current compensation, ensure stable welding current.


  1. Special design integration of pressurized cylinder which can ensure stability and mobility of pressurized and welding speed.
  2. Multiple same ways forced water cooling system to ensure stability and reliability of long-term operation.
  3. Upper and lower electrode adopt supplementary stroke pressurized mode which can improve the operability of welding process.
  4. Pressurized electrode speed can be adjusted, slow down the impact to welding work piece when pressuring , also reduces the noise when welding.
  5. Inrease welding stability. It can be used to preheat, to weld, to reform or to temper for special materials; Solve the problems of void welding or loose welding due to current shunt during the process of multiple projection welding. WD-10AC Controller : Digital circuit; Codes dialing regulating; Single discharge; When the voltage of power supply is fluctuated, it can automatically compensate the current to weld; Possesses the function of current climbing and the gradually increased current can effectively curb or reduce the welding splash.
