Web28 Jun 2024 · It works but when the frequency changes so does the triangle wave voltage from almost 0-3Vp-p to as low as 0,5Vp-p or even less. So I've got 2 options: a) do something about fluctuating triangle wave voltage or. b) build another circuit. IMO the way of generating the triangle wave and then converting it into square PWM isn't that bad. Web5 Mar 2016 · I had a Dialarc, used pure for AC sometimes. I prefer lanthanated, though I never tried 1-1/2%. I bought a bunch of NOS tungsten, and got bunches in welder purchases. I gave away the pure when I went to a square wave welder. I use mostly AC, and use all varieties interchangeably. Some need dressing sooner, but function they aren't that …
WebThe low power consumption and high efficiency of ENRX welding systems reduces costs. The high-speed troughput and reliability of induction welding makes it perfect for the tube and pipe industry. Ferrite for high-frequency tube welding. ENRX offer a full range of consumables, including coils, ferrite, impeders, and tube scarfing equipment. WebBecause square wave welding is a contact welding process, the 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 welding. Wider Heat Affected Zone
