Micro spot welders are also known as Linear DC welders. Micro spot welders load up energy in capacitors and release it through transistors. This produces a result very similar to the high frequency inverter power supplies. Clean square waves are created as the output with fast rise time. The micro spot welders made by AVIO are closed loop designs, using transistor controlled feedback with fast response time, with the ability to monitor the condition of the weld using one of three feed back modes, "constant current", "constant voltage", or "constant power". These feedback modes offer benefits such as excellent process consistency between multiple weld stations, fewer bad welds, and immediate automatic adjustment for variations in thermal loading and plating. Linear DC welders do not use a transformer. These power supplies' low energy controls are the best, making them the favorite for welding foils and micro wires. The fact that the duty cycle is typically less than one weld per second is the biggest limitation.

The Avio welders we offer are high quality Japanese welders. We stand by these welders and guarantee our customer's support and assistance when you purchase an Avio welder from us. AIT manufactures all electrodes in the U.S.A. Your questions and inquiries will be responded to quickly.
