What are the DC vs. the AC voltages of say, my Miller sticker? Ohm's Law may be on our side. BTW, I am almost always wearing rubber shoes or boots. Quack.
Doesn't matter if the current passes from hand to hand.... through your heart.

Does anyone know what voltages we are welding with at the stinger end? I'd like to know.
60 mA of AC (rms, 60 Hz) or 300-500 mA of DC can cause fibrillation. A sustained electric shock from AC at 120 V, 60 Hz is an especially dangerous source of ventricular fibrillation because it usually exceeds the let-go threshold, while not delivering enough initial energy to propel the person away from the source. However, the potential seriousness of the shock depends on paths through the body that the currents take. Death caused by an electric shock is called electrocution.
If the voltage is less than 200 V, then the human skin, more precisely the stratum corneum (the outermost layer of the epidermis), is the main contributor to the impedance of the body in the case of a macroshock-the passing of current between two contact points on the skin. The characteristics of the skin are non-linear however. If the voltage is above 450-500 V, then dielectric breakdown of the skin occurs. The protection offered by the skin is lowered by perspiration, and this is accelerated if electricity causes muscles to contract above the let-go threshold for a sustained period of time.
If an electrical circuit is established by electrodes introduced in the body, bypassing the skin, then the potential for lethality is much higher if a circuit through the heart is established. This is known as a microshock. Currents of only 10 μA can be sufficient to cause fibrillation in this case.
