Shieldarc - Look forward to seeing your coupon test results although I will continue to use 7014 anyway because I know it works for my limited skillset and it runs so smooth on my AC powersource. Regardless, it is always nice to see someone put forth the time, effort, and even incurr some expense to help others as you are volunteering to do. What is even more impressive in your case is that your willingness to help is not even slightly motivated for profit at any level. (For the record I do not mean this statement as a slight on Mark@Everlast, Jim Colt@Hypertherm, or others who post here that represent companies. Most of their posts are truly helpful, have good intentions, and in most cases are unbiased - but there are occasions that are bordeline sales pitches. While I appreciate their help too, they are motivated to help people for profit in their business - nothing wrong with profit since all businesses must turn a profit to survive).
Anyway, Here is that full chart that I promised to scan and post from earlier. It is a page from a Murex pocket electrode guide that also contains full specifications and is intended to help select the proper electrode (copyright date is unreadable from wear - got the book with my old $60 Lincoln AC-225. I am guessing the book is from mid 1970's to mid 1980's).
