DCEN or DCEP ????
Help me figure out which is which. Obviously "Electrode Positive" and "Electrode Negative" are self explanatory, but I'm having a little difficulty determining which has which characteristics. Getting ready do a little welding (SMAW) and it's been a while and I';m pretty low on experience anyway, so I thought I'd review the basics. Went to the local library and was thumbing though their collection of welding books. Out of 4 books, 2 say that DCEP has greater penetration and slower rod burn than DCEP and the other two books say the opposite. I thought I must have misread, so I opened all 4 books to the relevant pages and compared directly. Sure enough, 2 were saying the exact opposite of the other two. 3 are fairly thick, detailed, technical seeming books and the fourth, is a "here's how to weld" type aimed at hobbyists.
