I was wondering how many welding rods could be used with in 2 minutes of stick welding because my machines duty cycle is shortany advice appreciated thanks nickLincoln ac 225 tombstonea prayer

Reply:20% duty cycle at what amperage? Amps not rods will be the determining factor.
Reply:This is for a Lincoln 225 ac welder
The duty cycle is 20% at max amps.with breaks between rods and staying around 120 amps you may not hit duty cycleYour machine should have a similar type of chartLast edited by Bls repair; 12-20-2020 at 07:27 PM.
Reply:Yup, we simply need more info that you have not provided. We'll wait.
1st on WeldingWeb to have a scrolling sig!
Reply:Normally 20% duty cycle is based at full amps of machine. Less amps provides longer welding time. How many rods is hard to say. Are you welding continously ?? Say you want to weld a straight 24" of weld rod after rod is different than making 8 welds 3" long. The machine will have a minute maybe to cool while you change rods, chip slag, or wire brush. More info would help. Machine capacity, amps running, and rod. Sent from my iPhone using Tapatalk
Reply:I do not know what welding.But typically the 20% is at full ampage.Most time you not be working top end.Mig hand welding it ar about is 60%Stick welding is armost about 40%Dave

Reply:If you want to know time in terms of rods, then time how long it takes you to burn the rod at the amperage you are using.Then note how long you chip and clean and such. That will give you a good feel for how much rod to burn.Or, you can just put your hand in the air stream coming out of the machine once and a while. Sometimes it's very warm

Reply:What welder do you have ? Is it the Lincoln AC225 ? Unless you are running 5/32" rod continuously you shouldn't have a problem. I owned a lincoln 225ac for 10 years , and it wasn't uncommon for me to run 3 or 4 1/8" rods in a row with no break, and maybe even more lots of times welding old dump bodies with 6011. At some point you have to stop and clean/check what you welded. In reality few people ever hit the duty cycle on these welders. Never had a problem with the welder, got a fair price when I sold it too. What will you be welding ? Are you using 6011, 6013, 7014 ?HTHAirco 250 ac/dc Heliwelder Square waveMiller Synchrowave 180 sdMiller Econo Twin HFLincoln 210 MPDayton 225 ac/dcVictor torchesSnap-On YA-212Lotos Cut60D
Reply:Hi. It all depends on how many amps you are using. For Me. I do nearly all my welding with various 1/8" rodswhich require 120 to 140 amp so a duty cycle that gives you say 50% at 140 would allow me to weld almostcontinually if using 3/32" rods at 70- 80 amps the duty cycle would be a lot higher
Reply:thanks for the reply's, currently it is not a serious issue i just wanted an idea of what to expect with it. i have 5 lbs roughly of 6011 1/8 and 5/32, and 1/8s of 6013 and 7014. currently this is to be used to practice and get back to welding since i have not done much welding since college.again, thanks for your helpful replies,nickLincoln ac 225 tombstonea prayer
Reply:You have the machine. Try it.
Reply:FYI: Most of your welding will under 150 amps Your welding looks like 225 amp's @ duty cycle 20% so at 150 amps the duty cycle is 45%.Most stick welder are lucky to do a welding at 30% time. It takes time to clean the weld. When estimating I used 25% time.Dave

Reply:I cant see you even considering using 5/32.3/32 and 1/8 is all you need. Thats what we use for almost all pipe welding up to 5 or 6 schedule 40, depending. Sent from my iPhone using Tapatalk

Reply:i apologize for the long delay in replying. Where i am currently living, we don't currently have the 50 amp circuit it needs. It looks like we'll be able to get a neighbor pleaser made and possibly use the stove outlet, don't currently have projects but will find some from the internet. the question about duty cycle was a random question that i had as i was perusing the internet. i do have some pics of a project i welded for my dad that i can upload in the meantime. its a tool for keeping the pulley in his cars engine still while he loosens and tightens it. Hopefully we'll get the machine in action soon.thanks again for all of your input. It is appreciated.Nick

Reply:6013 3/32 amp range is 75-105 when i looked at Lincoln Electric website. i was using fleetweld 37 6013. it seemed to run good for me at 90,but, like i said, i had issues with comfortability. the angle pieces were all 1/8, the flat strips were 3/16, maybe pushing the limits for 3/32 im not sure. that rod seemed like the better choice for this little project.Last edited by buzz box hero; 02-05-2021 at 10:16 AM.Lincoln ac 225 tombstonea prayer
Reply:You're right on the Lincoln 6013 3/32" amperage. Sorry, for some reason I thought you were using forney 3/32" 6013, I've been using Hobart 447A(6013) 3/32" and it only call for 40-70 amps 80 amp max. so i've been running a bit lower than you. Although its odd, the box of fleetweld 37 1/8" I just got listed 90-120 amps, which is different from the Lincoln PDF : https://www.lincolnelectric.com/asse...d37/c21019.pdfI Generally start with the manufacturers middle listing and tune it in from there (as you did).For 1/8" angle to 3/16" bar , 3/32" should be good enough for an engine bracket to hold a pulley. Glad you were able to make good use of your welder, and I don't think you will have to worry too much about duty cycle until you get to much bigger jobs. 6013,6011. and 7014 should all run good on that welder, 3/32" & 1/8".Airco 250 ac/dc Heliwelder Square waveMiller Synchrowave 180 sdMiller Econo Twin HFLincoln 210 MPDayton 225 ac/dcVictor torchesSnap-On YA-212Lotos Cut60D
Reply:So this sounds like a dumb question coming from somebody that's welded for over 40 yrs, but what happens when you exceed duty cycle? Is there an internal breaker that trips, does it just flip the main breaker, or do you risk doing damage inside the welder? I've tripped breakers in the main box before, but never had any other problems.The harder you fall, the higher you bounce...250 amp Miller DialArc AC/DC StickF-225 amp Forney AC Stick230 amp Sears AC StickLincoln 180C MIGVictor Medalist 350 O/ACut 50 PlasmaLes

I've tripped breakers in the main box before, but never had any other problems.i would like to some heavier jobs in the future, though im not sure what exactly. i was looking to use the electrode consuming as a metering device. I am convinced that i could burn at least one full one without reaching the two minute mark, so i will go off of that for now. thank you very much for your reply.Lincoln ac 225 tombstonea prayer

After cooling start right back up unit it welds bad again.This will eventually ruin it.I overworked my first stick welder. I tig welded with it for way too long on max output. It popped a diode - replaced it and it welded fine again.I've seen engine drive machines over worked until the main armature started to come apart.New electric welders will just shut off, hopefully before damage occurs. But they don't shut off right on the duty cycle, as I understand it, they shut off after you've exceeded the duty cycle.An electronics guy explained it to me like this: every electrical component has a life span for heating and cooling cycles. The hotter it gets, for longer periods it is sustained, the life span shortens.

Reply:Ooooops..........you said you were running at 90amps.
Turn that down to 85amps
Reply:the next setting down is 75, i thought that would be too cold. if i had the dc one i think that one has an 85 amp setting.Lincoln ac 225 tombstonea prayer
Reply:time it takes to burn a rod usually about 1 minute, obviously depends on amperage..use machine on 30 or 40 amp breaker and circuit breaker will trip protecting machine from overheating as fast.obviously can use 6 ga wire that can handle 50 amps but still use on a 40 or less circuit breaker. this is a externalof welding machine overload protection rather than internal to welding machine. sure many newer machines havethis overload protection built into the machine. but if on a 30 amp circuit breaker that often works too..old fashioned machines dont shut off on overheating you usually smell the burning wire insulation smell and it takesa long time (often decades) before machine actually fails normally (cause most stop welding an let machine cool whenthey smell the burning wire insulation smell), 225amp machine sure you can burn a big rod or 2 and let cool off8 minutes but normally average welding is 150 amps or less. unless welding over 1/2" thick alot which is normally rare.and even if steel is 1/2" or thicker doing occasional jobs with small rod and using multiple passes is normal especially if welding upor overhead.Last edited by WNY_TomB; 02-07-2021 at 08:42 AM.
Reply:Did some welding today on my dads exhaust with his welder. amazingly, it was stick welding with 1/16 rods and without blowing holes!Lincoln ac 225 tombstonea prayer
Reply:Odds are it was E6013 1/16" It is a low pen rod I used for hole and gap filling. At time it was very common in shops. E6013 Also looks great too. The other rod was E7014 it we med. pen rod Also looks great too. Dave
