I want to believe this, but I can't wrap my head about how a DC TiG welder with 220v poly caps soldered across the output can create anything close to a waveform required for induction heating. Would we not just charge up the capacitors to a couple volts and get a short circuit at the copper tubing? For induction heating don't we need a baker's dozen kHz of AC at fairly high voltage and current? I would love to believe this works, but I don't think it's possible for that DC welder to make the high frequency AC needed.
Edit: Yup I'm going with this does not work and it's more fake DIY video nonsense. This little welder doesn't have the ingredients necessary to pull off induction heating.
Yep, if it is on the internet it must be true, NOTQuote:

Yup. 4N60 600 volt MOSFETs and 1200v capacitors. Much more likely that's a working circuit. Well, working at least briefly.
a lot of things work briefly, but if I buy or build something I want to know that it will have a 100%duty cycle for its intended purpose or years to come, not a few minutes or secondsQuote:
