MFDC Controllers
MFDC Controllers
ARO provides a standard range of MFDC welding cabinets covering manual, robot and stationary machine applications.
They integrate a complete and coherent range of inverters (also available as components) with embedded controllers compatible with a large majority of field buses such as Ethernet IP, Profinet IO, DeviceNet, Interbus-S, Profibus DP.
- Ability to manage up to 256 welding schedules
- Wide choice of options
- Compact design
- Worker safety
- Maximum flexibility
- Adaptive Welding and Quality Assurance
Adaptive Welding
Self LEARNING
Possibility to copy the Learning (reference) from a gun to any other
Adaptive mode will compensate :
▪ Different materials and thicknesses (for manual welding)
▪ Tips wear
▪ Presence of adhesive
▪ Poor part fit
▪ Shunting effects
▪ Shunting effects
Adaptive Welding
Intelligent and efficient, Adaptive Welding automatically compensates process variations to guarantee superior weld quality.
SQA (Steel Quality Assurance)
- Steel Quality Assurance function (SQA) assigns a % to each spot to grade the quality of the welding
- Dedicated to robotized applications, the principle is also based on dynamic resistance during the weld formation
- It povides with weld quality and process deviations
Features
- Three phases balanced current : Lower electrical consumption ( Over 20% saving)
- Welding current is not disturbed by main network voltage variations
- Better welding quality/Lower welding current/Spattering reduced
- Lightweight equipment
- Improved weld quality
- Reduction in time and associated cost savings for equipment start-up
- Reduction of expulsions which minimizes maintenance costs
- Reduced off-line quality control expenses
- Easier welding of complex materials (HSS, AHSS, PHS -boron, etc.)
- Evaluates weld quality Detects process disturbances (mechanical and electrical
failures, shunt effect, different coatings, adhesive, electrodes sliding etc…) - SQA can be used either in standard or adaptive welding mode
- Automatic reweld function based on SQA%
- Threshold of the SQA% is set by the weld engineer
