You might use the word "Breadth" to mean width.Girth is also used used to mean circumference.The width of a ship is its "Beam".If you talk too much about "Berth", people may think you're sleeping on the job.Rust (as well as paint) is not a good electrical conductor. And, thus I usually clean off a spot of clean metal before attaching my grounding clamp. And, everyone recommends cleaning your steel before welding. I don't use a welding table at this time, just clamp the ground to a clean spot on the work.Many power supplies fail to give you constant voltage. I wouldn't be surprised if your power supply produces essentially 0V when away from the metal (perhaps also adding high frequency).The high frequency (or scratch start) will start your arc, then you will have about 30V or so when welding. But, if you put it through a good resistor (bad contact with the metal or ground), you may in fact get a much higher voltage... 100V or so?It isn't the rust that is knocking your socks off, but rather your welder that is having troubles dealing with an abnormally high resistance circuit.You could probably verify by attaching a cheap (Harbor Freight) voltmeter between the electrode and the ground. Then striking an arc with a relatively poor ground connection.

William - this is an official mod note. Stop the non-mainstream rambling and pronouncements on the main boards. If you can answer questions with acknowledged and recognized science then please do so - and your anecdotes and notions would be welcome on the New Theories board, but please do not continue to post them here. I will start shrinking your posts if you continue.
I would love to know what I said about dielectrics that is not mainstream?I would love to know what I said about common welders that is not mainstream?
ARC used to stand for Anode, Rectified Cathode, Sincerely, William McCormick

I hope you know that science has nothing to do with peer pressure at all. So your use of it defines, you as a poor scientist. That is just how it is. I know anyone can be a great scientist, you just have to have the courage to be yourself and form your own opinions, based on facts. No matter what ten, a hundred or ten billion think.
If you understand electricity you know the batteries are labeled backwards.

No matter what ten, a hundred or ten billion think.Correct,Science isn't about peer pressure, although much of it is based on peer reviewed literature. And, if one has a novel idea, or an idea that goes against the norm, then the person must have the facts and data to back it up. So, for the most part science is more about data than opinion, although there is a grey area as one considers different interpretations of the data.Quote from: William McCormick on 26/08/2012 20:26:55If you understand electricity you know the batteries are labeled backwards. It isn't that batteries are labeled backwards. + or - is an arbitrary label.The problem is that in elementary electronics, electricity is often considered to flow from (+ to -), but later it was discovered that the elementary particles, protons carry a positive charge, and generally don't move (although they are used to transmit electricity in cells). And, that the electron is the subatomic particle with a negative charge that is most mobile. So, the flow of electrons is actually from (- to +)For many things flow from (+ to -) or (- to +) doesn't make a big difference as one needs a circuit, although it is a consideration that welders have to determine heat distribution.
