MTK-8502


Capacitor discharge welding machine. Designed for capacitor stored-energy resistance spot welding of large-size parts made of light alloys, titanium, stainless and high temperature steels.
Functional features and advantages:
- Provides high stability of operating parameters and quality of welded joints;
- 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.
