MTK-5502

   Capacitor discharge welding machine. Designed for high-precision welding of segments made of stainless steel and light alloys in accordance with welding requirements for aerospace hardware.

 

Functional features and advantages:

 

  • Welding of similar and dissimilar metals;
  • Enhanced welding current stabilization by changes in supply voltage.
  • Discrete control of complicated welding cycles.
  • Adopt pneumatic parts by SMC firm (Japan) providing high accuracy and reliability of operation;
  • Adopt special sensor of welding current in a secondary circuit which allows to control value of actual welding current delivered to the weld on each pulse;
  • Multy-function microprocessor based control system with the sensor LCD monitor;
  • Convenient programming of welding parameters in physical units of measurement;        
  • Monitoring and diagnostics of key parameters of a welding cycle;
  • Storage in a non-volatile memory up to 500 welding schedules;
  • Overload current protection;
  • Monitoring of water circulation through machine elements critical to overheating;
  • Pass-word protection from un-authorized change of welding parameters;
  • Programmable limits of welding current and electrode pressure, which assure on-line quality control;
  • Registration and recording of the following parameters during each weld:
  • welding schedule;
  • welding execution: date and time;
  • values of welding current;
  • welding and forging forces, etc.
