Yoder Square Wave ERW Welder - Formtek
Because square wave welding is a contact welding process, the heat transfer efficiency of the process is much greater than HF induction welding. Although HF contact welding is also a contact method, it is generally not used on the smaller tube sizes and, therefore, does not typically compete with square wave … See more For a full appreciation of the square wave welder, it is necessary to review the history of ERW starting in the early 1920’s. Prior to that time, welded … See more In Johnston’s preferred version, the weld was produced by a sinusoidal AC welder. The output voltage and output current for an AC welder are illustrated in Figure 1. By taking the instantaneous product of the output voltage and … See more The goal of the Square Wave Welder was to combine all the good things from both conventional AC welding and DC welding. This meant a welder that was as easy to maintain as an AC welder but delivered the performance of a DC … See more DC welding was first used in an attempt to avoid Johnston’s patent; however, it is obvious that a DC power supply with a constant power … See more Web8 May 2007 · Based on the size of your estimated demand, I would recommend a sinewave inverter. They are kind to motors & electronics, and the price is reasonable below about 1KW. Usually available at your local RV or marine suppliers.
