This probably doesn't deserve a whole thread, but I couldn't find a good place in any existing threads to put it.
Can someone explain to me why, in Miller's "TIG Handbook", page 6, Figure 2.2, the diagram shows current flowing from the positive side of the voltage source, through the TIG torch (which is hooked up backwards, DCEP), and then returning to the voltage source at the negative side?
Is this a mistake or am I confused?
"Current" refers to the movement of electrons, which are negatively charged, towards a positively charged sink, right? So as far as I can tell, the diagram is fine, except that the "+" and "-" signs are reversed. Right?
