Induction heater from welder - video

[nova_robotics]

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.
