Assurance Plus weld control system
The complete weld control for flash or butt (upset) welding, designed and patented by Automation International. Built in the USA and a drop-in replacement for earlier Assurance controls.
- 16 channels
- Diagnostic graphics
- 16x
- Input converter accuracy vs the previous system

What stayed
The patented weld cycle logic and force controller, the 16 channel diagnostic graphics system, the flexible statistics packages, and the same I/O pin-out as the previous Assurance control.
What changed
A low power, low heat controller with no heat sinks or fans, all surface mount components, optical isolation from machine signals, and input converters 16 times more accurate than before.
Networked by design
The weld controller runs a TCP/IP server, so it can sit close to the signal sources while the HMI goes wherever suits the operator, such as a pendant.
Architecture
Three computers, one control
DSP weld controller
Executes the weld control logic with millisecond precision.
Industrial PLC interface
Manages machine safety, hydraulics and auxiliary systems.
PC-based HMI
Touch screen interface with graphical weld visualization, for Windows or other operating systems.
- Real-time thermal and force feedback
- Adaptive programming for dynamic process adjustment
- High-current capacity for heavy-duty welding
- Diagnostic graphics for real-time and historical weld analysis
- Statistical process control, with data export to standard SPC software
- Role-based user permissions and printed reports
- SQL Server database, with remote service access
- Plug-ins for tagged weld data such as barcodes or GPS



Retrofit
Upgrade the control you have
An existing Assurance system can be retrofitted, and so can a control from any other maker.
All Assurance systems are assembled and tested in the United States, with on-site commissioning, operator training, and remote diagnostics and updates.
Common questions
Will Assurance Plus replace my older Assurance control?
Yes. It keeps the same I/O pin-out specifications, so it is a drop-in replacement for previous generation Assurance controls.
Can it be fitted to another maker's welder?
Yes. Automation International can retrofit your current Assurance system or any other system you may have.
Where is weld data stored?
In a SQL Server database. The HMI is network enabled for remote service and for offline setup editing and weld database tools.
