I will restate some points from my last post:
Safety is related to the voltage found in the circuit, not whether it is AC or DC.
UL, CSA and all the other international safety agencies consider anything over 50 Volts AC or DC to be a hazard. (Both AC and DC can kill you. We have warning labels on our battery systems at work since they are up at 288 Vdc and 360 Vdc)
It only takes a few thousanths of an Amp of current flowing through certain parts of the human body to cause death. (This is from the training that we receive at work, where we really have to know what the real deal is)
Please don't confuse voltage with current (Amps). It makes a big difference.
Welders and cars (except the ignition circuit) are low voltage systems, below 50 V. The higher the voltage, the higher the current that gets pushed through a given resistance (I = V/R).

"the concern here was and is you came in here with out any of the cautions
advised and you need to remember 100's are looking and could be trying this out, caution to all..."
On other websites that specialize in posting experimental stuff that may be hazardous typically have disclaimers warning that anyone following the instructions are doing so at their own risk. I have already pointed out in a previous post where something is heading for a "big bang".
Knifemakers already use some rather hazardous equipment and materials. In virtually all of these cases, someone who gets hurt has the time to go get help. Some have posted pictures of their injuries or posted about how they drove themselves to the hospital. When one is electrocuted and gets enough current flowing throught the body, one's heart stops or flutters. Typically, breathing is stopped too. Typically, one becomes INCAPACITATED meaning one will not be able to help oneself nor would one be able to seek help. Permanent brain damage occurs within several minutes. Death follows a few minutes later. ELECTROCUTION IS MUCH LESS FORGIVING than any other injuries that one is likely to experience in a typical small/home shop. I don't hear about very many people who are electrocuted posting pictures of the burn marks on their skin afterwards.
The conductivity of the human body is dependent on a lot of factors and changes from day to day. When one "gets a tingle" or some other mild shock, one has just cheated death. On a different day, the same voltage may be fatal. I would rather read posts about the cool stuff you guys make than posts that start "Did you hear about ..."
