Providing you with equipment and technical support
Lower prices on equipment and electrodes than other manufacturers
Shorter lead time, especially on electrodes
Free test weldsand unparalleled customer support

How We Can Help You

We have chosen the AVIO line of equipment because it offers advanced technology, precision, and quality at a reasonable price compared to other popular brands. Our inverter spot welders utilize pulse width modulation to control weld energy, resulting in DC current with low-level AC ripple. With high repetition rates, inverter welders are useful in industrial automation and are built such that they can be wires into automated systems and controlled by a plc if needed.

We can assist you with any technical issues you encounter during the setup of your welding process, and we manufacture all electrodes in our facility in the United States. We can even build custom electrodes to help resolve any welding issues you encounter.

Closed loop welders like inverter type (high-frequency inverter) and transistor type (linear DC) welders can control the welding waveform's shape and monitor the weld's condition using feedback modes like "constant current," "constant voltage," or "constant power." These modes offer advantages such as better process consistency, reduced weld failures, and automatic adjustment for variations in part thermal loading and plating. Our Avio inverter spot welders are premium quality Japanese-made high-frequency inverter welders that utilize these feedback modes to provide superior welding results.

About Us

Advanced Integrated Technologies is essentially a manufacturing service company with two major divisions. The resistance welding and reflow soldering tool division grew out of our early work building micro tools for Hughes Aircraft. About the time that Microsoft was turning computers into a household item, computer hardware manufacturers were looking for companies to build reflow tools used in the assembly of hard drives and other components.
