right click and open in new window.
looking for a cure for cancer = new fuel, burning salt water for fuel, now thats American.

Amazing if true.

I'm dubious though.

Interesting. You have to think about all the RF radiation though. That has to be a high power device as radars and radio antennas do not cause Salt water to burn. People are worried about Cell Phones which have a tiny amount of radiation compared to radio towers, how much radiation would this be in cars?

My company had the owner of Thermex Thermatron come out and do a seminar on RF. We have over 40 RF welding machines, some up to 50kw. Some of these vacuum tubes are the size of big thermos bottles. He claimed the frequency they ran at (about 14Mhz) is perfectly safe. But when he spoke on a cell phone, he held it with the tips of his fingers and used the speaker. Too much radiation.

Just curious, can you tell me his name? We have some Thermex Thermatron RF welders as well. Ours are 27 Mhz and 45 kw. We use them to weld the plastic on those unopenable blister packs that you buy all kinds of electronic stuff in. Just curious as to who it was, if it is someone I have worked with. I am an RF Engineer and do Cell Phones for a living and I always get a kick out of that fake video of people popping pop corn with 4 cell phones. That one scared so many a few years ago and it is all fake.

Joe Wicked,

It was Bill Hall from Hall Dielectric, not Thermatron, Faratron, et al. Sorry about that.
He did a nice one day course on the fundamentals of RF welding including design, tuning and maintenance.
We've got machines from all of em but our 30 and 50 KW's were custom jobs. My father had the 50's made so he could weld a waterbed mattress in one shot back in the 70's (the stories I've heard about the waterbed trade shows ). Our machines are mostly 27.12 Mhz but our big boys are half that, to reduce resonant frequencies.
We don't weld the rigid PETG type stuff. We RF weld flexible vinyl and urethane for the military and med industry.
At any rate, Bill Hall's class was informative for us. Maybe not if you're an RF engineer.

[Joe Wicked]

Cool. Any good class is always worth it even if it is information you already know. Reinforcement of that info is always a positive. I am not familiar with Bill Hall, so I don't know his background. We have the Thermex-Thermatron units only right now and we use each to weld 4-8 PETG clamshells at once depending on size. If you are at a store and see any Samsung cell phones or cell phone accessories in the blister packs, they were welded here.
