Linear DC Welder

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.

Transistor welders are also known as Linear DC welders. In a transistor welder, energy is stored up in capacitors and released through transistors. This produces a result similar to the high frequency inverter power supplies. The output is in the form of clean square waves with very fast rise time. The transistor welders made by AVIO are closed loop designs, utilizing transistor controlled feedback with extremely fast response time, which are able 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 great advantages such as better process consistency between multiple weld stations, reduced number of bad welds, and real time automatic adjustment for variations in part thermal loading and plating. Linear DC welders do not use a transformer. These power supplies have the best low energy control, making them the favorite for welding micro wires and then foils. The major limitation is that the duty cycle is typically much less than one weld per second.
The Avio welders we are offering here are premium quality Japanese made welders. We stand by these welders and guarantee our customers support and assistance when you buy an Avio welder from us. All electrodes are manufactured by AIT in our facility in the United States. We can respond quickly to your inquiries or questions.
