Fully automatic, process-controlled and mobile multifunction spot welding machine with 10 kHz medium frequency inverter technology, active cooling and different guns assembly according to requirements.
The MIDIspot VISION AV is designed for mobile and flexible use in the industry and in automobile plants (small series, prototype construction, pilot halls and reworking).
Designed to operate with all ELMA-Tech 10 kHz spot welding guns in C-, X- or V version.
Resistance spot welding of vehicle bodies, especially of components made of higher-tensile, high-strength, coated and bonded steel sheets, as well as metal compounds with quality statement about the welding result (no parameter determination necessary). Thanks to the unique control technology "Virtual Machine" new plates can also be welded without any additional settings.
Welding methods
All the necessary welding processes in one device:
- Current / time conventional (constant current regulation)
Adjustment: single-parameter
- Energy control: bypass and partial isolation compensation, quality assurance system "ELMA-QS"
Adjustment: total sheet thickness, type of material
- Fully automatic process control of welding (VISION)
Adjustment: None - just activate the start-trigger!
Automatic detection of total sheet thickness
Automatic detection of the type of material (normal / high-strength)
Automatic determination of the welding nugget size by continuous process control of the total energy input
- Spotting (optional)
Applications
Industry and Automotive (with active cooling and, if required, also with powerful spot welding guns ELMA VISION CM/VM)
