Reply:or these?http://www.hobartbrothers.com/products/Looks like they all fit the AWS 7018-1 classification.
Reply:Does one say 418 on the box?  If so, that is a fantastic rod with a yellow glass like slag.  It welds flawlessly.  But the slag can be a bear to remove.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT
Reply:-1 info from: http://www.aws.org/wj/feb/wjarticle.html For filler metals, AWS has also adopted supplementary requirements and these are identified with "optional supplemental designators."Therefore, as was shown earlier, an E7018, meeting all the basic requirements of the AWS A5.1 specification, will show satisfactory toughness values down to at least *20°F. Some trade designations of E7018 will show satisfactory toughness down to a lower *50°F. These also can be classified as E7018 because they meet all the basic requirements. However, they can also carry the optional supplemental designator of -1 and can be designated, labeled and marked as E7018-1.Obviously, the E7018-1 can be used anywhere the E7018 is specified because it meets all the requirements of an E7018. However, in situations where toughness is required at lower temperatures than afforded in the basic requirements of E7018, then E7018-1 can be selected in order to give reasonable assurance that the toughness down to *50°F can be attained.Refering to Lincoln info at: http://www.pirate4x4.com/tech/billav...7018%20rod.pdf  (also found at Lincoln proper) the -1 designator has a Charpy rating to -50F.  Regular 7018 Charpy value has a rating of -20F  Looks like the -1 rod is the one we should have used in Antarctica as we had a problem with weld fractures.Some more on electrodes:http://www.esabna.com/EUWeb/AWTC/Lesson1_1.htmLast edited by Jim Riley; 02-16-2009 at 11:00 AM.
Reply:it seems that hobart brothers makes electrodes..for hobart.. but i cant understand why the hobartwelders site, which shows electrodfes, does not include this one.. many thanks.. it seems the -01 means it works better in real cold weather...
Reply:Hobart welders and hobart filler metals are seperate companies, both owned by ITW.  Used to be together, but were split apart due to Anti-monopoly regs when ITW made the purchase several years ago.Others answered your question about the -01 designation, so I'll leave it there.Regards, Originally Posted by weldbeadit seems that hobart brothers makes electrodes..for hobart.. but i cant understand why the hobartwelders site, which shows electrodfes, does not include this one.. many thanks.. it seems the -01 means it works better in real cold weather...

Reply:And Bernard, and weldcraft, and a whole bunch of other companies.  I don't pretend to understand FTC regulations, and such.  But I think that's why both companies have the Hobart name, but don't list the same stuff on their product webpages.
