Does this ionization cause electrical disturbances that can be heard on an AM radio? If my neighbor is using an oxyacetylene torch will I hear the electric noise on my AM radio? Can nearby analog televisions also experience visual disturbances from the ionization caused by the oxyacetylene flame?

Hi: An oxyacetylene flame -- due to its high temperature -- can cause nearby air molecules to ionize. Does this ionization cause electrical disturbances that can be heard on an AM radio?

In addition, electricity can pass more easily through a flame than through room-temperature air.

Is there a net electrical current? If not, then no. The intense heat from the flame might cause certain compounds in the air to dissociate into ions. It is called a plasma, and both charges travel together. No net electrical current. Quote: If my neighbor is using an oxyacetylene torch will I hear the electric noise on my AM radio? Plasma torch, likely. Electrical welder, certainly. Oxyacetylene torch, probably not. The heat and light of the flame is due to electric forces in the chemicals being burned. Right? Actually, it is caused both by the momentum of the various atoms, and the light released in the chemical reaction(s). Quote: Can nearby analog televisions also experience visual disturbances from the ionization caused by the oxyacetylene flame? Probably not. A flame is a form of plasma. In addition, electricity can pass more easily through a flame than through room- temperature air. But there is not a potential difference to cause unbalanced current flow. If you want to mess with him, though, you could cause his plasma to talk to him. http://en.wikipedia.org/wiki/Plasma_arc_loudspeaker .... "THIS IS THE VOICE OF GOD.

Usually, a magnetic field is needed as well to create an ion current in the hot gases. The exception is electric sparks. Usually, you don't start thinking plasma until you're up in the many thousands of degrees. The plasma torches used in ICP are initiated with a spark and then inductively self-heated with an oscillating magnetic field. OA flames are like Antarctic ice by comparison.

However, as things are a little slow over at alt.binaries.pictures.nospam.post-yourself-nude, I took Leo D's advice (There is no higher or lower knowledge, but one only, flowing out of experimentation. ) With my Miller 301G set at 300 Amps DC - with the coupon 4-foot from a radio set to a strong local AM station there is no effect. There is however, the possibility that an AC welder, would generate high frequency harmonics and cause interference, personally I doubt it. With my Miller Spectrum 2050 plasma cutter -- radio 45-foot away (so I can hear it over the air flow from the torch). When la machine is turned on you hear chuff-chuff- chuff w/ the signal. When cutting - white/pink noise completely wipes out the signal. Now - unless the Democrats revoke the inverse-square law, I doubt this effect would travel far. If I could find a volunteer the radio could be move away and we would know for sure. -- donald j haarmann --------------------------------- And the public has always responded to a buccaneering spirit in engineering, the idea that enormous risks are being taken, that enormous reward is the prize, but that total disaster is a looming possibility.

Can nearby analog televisions also experience visual disturbances from the ionization caused by the oxyacetylene flame? No, I have never heard of such interference being a problem anywhere before and any net flow of current will be far too small and it will be dc. A spark would produce a transient rf pulse but you would require an alternating current or a series of sparks to get continuous rf.
