how many stick electrodes within 20% duty cycle

[buzz box hero]

I was wondering how many welding rods could be used with in 2 minutes of stick welding because my machines duty cycle is short
any advice appreciated thanks

Some variables such as size and type of rod and how many amps going through the rod.

[12V71]

20% duty cycle at what amperage? Amps not rods will be the determining factor.

[Bls repair]

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 cycle

Your machine should have a similar type of chart

[Oscar]

Yup, we simply need more info that you have not provided. We'll wait.

[BD1]

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.

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%

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

[Brazin]

The short answer is 2 minutes worth at full power followed by 8 minutes of not welding.

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 ?

Hi. It all depends on how many amps you are using. For Me. I do nearly all my welding with various 1/8" rods
which require 120 to 140 amp so a duty cycle that gives you say 50% at 140 would allow me to weld almost
continually if using 3/32" rods at 70- 80 amps the duty cycle would be a lot higher

[buzz box hero]

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,

You have the machine.

Try it.

[smithdoor]

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.

thank you, i appreciate your reply!

[BD1]

I can’t see you even considering using 5/32.
3/32 “ and 1/8” is all you need. That’s what we use for almost all pipe welding up to 5” or 6” schedule 40, depending.

+1 on that.

If your just padding beads on a plate, you'll have that plate glowing before that machine has any problems with duty cycle. You'll probably want to stop before the welding machine does. When you run 6 of the 5/32" rods in a row down to stubs you'll find out how good your welding gloves really are. https://www.weldingweb.com/images/smilies/laughing.gif

Post some pic's of what you're welding.

good luck

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.

not very pretty, but mostly because i have difficulty getting comfortable

[buzz box hero]

this was done with 3/32 6013 at 90 amps

[albrightree]

this was done with 3/32 6013 at 90 amps

90 amps seems a bit high for 3/32", maybe 60-65 amps.

Forney Product Specifications:
Recommended polarity: AC, DCEP, DCEN (either polarity)
Diameter: 3/32" (2.38 millimeters)
Weight: 5 lbs. (2.26 kg)
Tensile strength: 83,000 PSI
Amperage: 50-70

Hopefully you can get a good electrical connection so you can practice more. If all of the material was thicker than 1/4", an 1/8" dia welding rod might have been a better choice.






Hope This Helps

Best of luck.

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.

[albrightree]

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.pdf
I 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".

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.

From what I've seen, you start cooking internal parts. I've found a few welders that were run hard that the coating was coming off the windings.

Old machines didn't have anything to tell you this was happening, but I've welded until the machine starts welding badly.
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.
