How We Can Help You
Advanced Integrated Technologies ( AIT ) is a resistance welding equipment and technical support provider for Nippon Avionics ( Avio ) brand of resistance spot welders and accessories as well as Sunstone brand spot welders. We can evaluate your product samples, provide free test welds, and accurately specify which equipment is best for your application. We can then provide the equipment you need at an economical price, and assist with any technical issues you encounter setting up your welding process. Submit a contact form or call us today to request assistance with your next project.
AVIO Welders
These AC spot welders are most suitable for welding thick plates and copper stranded cable, as it can adjust the weld time through a wider range than other stored energy type of welders. The lower peak current is less affected by dirt or stain on the work piece. These are very suitable for integration with automation. AIT builds all of our own electrodes for use in these and other welders that we provide to our customers. We can provide custom electrodes and solutions for your welding applications.
Suitable weld heads and other accessories are available for all the welders featured below. It is best to contact us and describe your welding application in detail, and allow our technician to work with you in determining the best power supply, weld head, and electrodes for your specific applications.

Sunstone Welders
These AC spot welders make use of an internal transformer that provides ample power for many applications, making them ideal for resistance spot welding and seam welding. Both of these welders also make use of a microprocessor that allows easy setup and programming for complex welding sequences, such as linking different weld schedules together within the same job. Either of these AC spot welders are capable of welding thicknesses up to 0.1 inch.
