I think his point is the concept that close proximity has enough energy to induce an electrical current. Much like an electric toothbrush charging through induction on a dock, the phone allegedly had enough magnetic flux to activate the helmet screen (no light required).
It's easy to see that cellphones have magnetic fields, just hold one up to a compass to see. OP's claim is about an observation related to the magnitude of energy coming from cell phones. I can't vouch for his specific claim about welder helmet auto-dimmers, but the premise is coherent.
Correct, and magnetic fields can induce electricity. But, not all electronics have enough energy throughput to generate strong enough fields to activate nearby electronics.
It has to be pretty sensitive. Not surprising RF sound be picked up by poor shielding or the light sensor itself. Some Geiger counters/scintillation detectors also get triggered by RF.

Because the hood is supposed to block bright light, idiot.

All electronics have magnetic fields. That's how they work. Electricity induces magnetic fields when moving through metals and such.
