I have always used the same rod on my old Lincoln buzz box as I do with the Miller DC welder. They do have a 7018 AC rod but I am way to cheap to have both. After two days I probly couldn't tell the difference anyway. If your a kin to, it will make you use some non church like words lighting the fire at first. The weld will work look the same on both machines. If I was you I would most likely stick with what I have used the most also.

7018AC ONLY rod to use !! 6013 is NO good on AC ! sputters and makes a mess... I've got 25# of it here, minus 4 rods you can HAVE... also smells like smouldering/burning overalls... you NEED an AC rated rod for an AC only machine..... 7018AC works great on new steel, old steel, thick or thin... 3/32 and 40amps for rider decks, 1/8 and 105 amps for the rest....

Joe it has to be 7018 AC and some welders (my Miller AEA non AC) don’t like it.

Hey Thad,,,so you CAN use 7018 with an AC machine,,?? HMMmm,,I was always under the impression that 7018 was made for the DC machines,,,,is why I never tried to run the 7018 and instead been running the 6011 and recently the 6013 which I was told are primarily for the AC machines which mine is,,,,,Chit,,I'm all fu'ed up now,,,

I used to buy rod at NAPA and had good luck.
I like the Hobart 7018AC with my Lincoln cracker box but my Miller Aead AC engine driven doesn’t like it at all.

I use 7018 same as Dick... but I bet he is using a DC welder as I am...That is the only rod to use with DC welding... I have not tried the 7018AC as I have not used an AC welder in over 30 years... I have bought off brand 7018 rod on e-bay for a test, and I have had great luck. Most 7018 rod has a "manufacturing spec" and has to meet very strict criterial as that rod is used by Boiler Maker / Pipe fitter ( Union welders) at Power Plants and Oil fields.

I only use 7018 on all fab steel. High tinsel low hydrogen. It is a bit stick lighting it on fire until you get the hang of it. I use it on P20 mold base steel also as a filler. I tig mold cavities when needed with the appropriate rod.

6013 is a mild steel somewhat general purpose rod but not a great choice. I too use 7018, get them from the steel supply house I buy my bulk materials from, not been unhappy and cannot find the name on the rods.

7018AC, brand name is the ONLY rod I use with my Lincoln AC-225-S welder for the past 30 yeras. tried others but prefer the 7018AC... AC means GREAT for AC welders.... With 3/32 rods I can weld thin rider decks, 1/8 welds everything else. I usually get Hobart...shop at same store all the time.... 1/2 priced rods will cause you 2X the grief ! Buy a QUALITY rod, stick with it ! ( no pun intended )

Faced the same problem here with 7016 rods Joe. Welding supply shop man said they replaced the 'top name' brands with a Korean made brand. My thought was what the hell use will they be. He said take some and try them, you wont have any problems with them because all my professional welder customers don't. He was right. They are an excellent rod. I was wondering if brands like Lincoln have been made in Asia for down here for a while anyway.

Well,, the local weldin supply has stopped carrying the 1/8" 6013 Lincoln and the Hobart stick weld rod I been using forever and now carries a Radnor brand, so I got a 1# tube to try it out and did not like it too good,, And my old lincoln 250 cracker box didn't want to run it too smooth.,,guess I was used to the Hobart rod. TSC carries the Hobart rod but is just bout twice the price of what I was payin at the weld supply,,!chit fire,,I told the dude there I was gonna talk with Ms Big ones and,,,and,,he tells me she got transferred to a store in Omaha,,,ain't that a beach,,,,,,,!!!!! AND,,I ain't gonna pay what TSC wants for the same rod I had been payin at half the price at the weld supply,,, I looked on the Internet and see some Forney weld rod and some Hobart for some dang good prices. Does anybody use or got anything to say bout the Forney rod,,?? Or some other good brand of stick rod,,,??? I really like the Hobart rod because of it's quality and smooth running and welding is something I do NOT not short cut on,,,
