i am kinda new to welding. i have welded lots before on farm impliments and such but nothing that really mattered. i have a few cert. welders that are gonna help me out with some trailer idea i have for mu business Mid-GA Outdoor. my sister os one of them. anyways. my dad has a Century 230amp welder that is AC. i usually use 7014 rods. what am i SUPPOSED do use for this AC welder?
Reply:An AC welder works best with AC rods. 6010 & 6011 are basically the same rod, except 6011 uses a different flux designating it AC/DC. Below is a pdf. from Lincoln telling sizes, polarities, positions and what to run them on etc. These are Lincoln only rods but most of the rod numbers if not all are universal. Maybe this will help get you started.

Reply:Originally Posted by DSW7018 is a low hydrogen rod and doesn't do well on open roots because the back of the weld is open and unshielded. You run 6010/11 usually to close up the open root and then weld out with 7018. You usually would not use 6010/11 if you had a joint that did not have an open root or if you used a backing strip. Then you could weld out with 7018 from the start with no issues.
Reply:I can't edit my post after a few minutes - but I think I understand what you're saying now. By "open root," you mean when there's a space between the two pieces you're welding together. If that's right, it clarifies everything you said.
Reply:learn to run 1/8 6011 and 7018 the most useful to me.i buy 6011 50 lb at a time and 7018 5 lb at a time as needed.millermatic 35 acdc thunderboltesab 2522 oxweld w-17 torchesesab plasma cutterspeedway fluxcoreold bug gas welderROLL TIDE

Reply:On my Lincoln AC-225 buzzbox which is AC only I mainly use 3 rods:a) 7014 is my favorite rod and runs excellent on AC power. (idiot rod almost welds itself)b) 6011 for dirty and rusty stuff or anything requiring deep penetration.c) 6013 also runs nice, but is more suited for sheet metal due to low penetration qualities and 6013 not know for best strength properties so I only use on non-critical stuff.If you feel you just have to have 7018 for some reason like when welding alloy steels instead of common regular mild steel then I would opt for 7018AC over standard 7018 as it will run slightly better on a smaller buzzbox - but any 7018 can be tempermental. Since I never weld any alloy steels then I do fool with the hassles of 7018.Last edited by rankrank1; 07-09-2011 at 01:33 PM.

oaded question. If you don't know what rod to use to build a trailer...DON'T build a trailer! 6011 is a great rod for welding, but requires practice. On a trailer, I would weld it together with 6011 and cap it with 7018AC. The pdf. I gave you explains that the 60 in 6011 stands for 60,000 lbs. tensile strength. The first1 is for "all" positions. and the other 1 is for the flux. So 7018 means 70,000 lbs tensile strength, all position rod with a different type of flux than 6011. The pdf. tells you exactly what the flux numbers stand for, I didn't go look it up, just giving you quick explanation.Only when the last tree has died and the last river has been poisoned and the last fish has been caught will we realize we cannot eat money. -Cree Indian ProverbSA 200 LincolnVictor Torches

Reply:Originally Posted by RuarkAny particular reason you would use 7018 instead of 7014? Also, are you talking about tube-stored 7018AC, or oven-stored?Where I'm coming from is, I'm trying to decide on a 2nd "go-to" rod besides 6011 for my 235 AC welder, and I'm tossing between 7014, and tube-stored 7018AC. This is for miscellaneous home and ag use, from 1/8 to 3/4 inch metal.
