Well, it sure lookin like ole TBone and Steve and the other Steve have just about narrowed down to it being the friggin Lincoln machine,,,, I got my Multitestor and checked the legs on the 220 going to the work area and got 120 VAC on each leg,,same for the actual plug. Even plugged in an extra 3 prong dryer plug into that outlet and read those ends and also gots 120 VAC on both legs,,,,, SO,, I moved that Old Timer machine into garage,,It is FRIGGIN COLD in these parts these days,,was and STILL IS 17° with no wind,,,!! anyway, I wired up the Dryer plug into the machine,,used a 3/32 7014 rod with machine set at 70 amps and,,,,and,,,that sob took off like an old "Hot Rod Lincoln". Just as purdy as you please!!! Chit that 7014 ran so purdy,,,can't hardly believe it!! SO,,,me being JOE, I took a stick of that 7014 and turned on the Lincoln and that sob failed miserably!!! It stuck,, Pharted ,, slid around missed,,,!! OK,,,,,what could be wrong with The Lincoln???? I removed the cover and checked the volts right at the switch and is getting the full 220 VAC,,,,,,?????

That's why I use 7014. 7018 often is difficult to start. Generally have to break flux away from tip to ensure a clean start. Much easier to just use 7014 which has better penetration too, (see Miller chart).

i would look at all the bolted faces and contacts on the switch.. may be corrosion BETWEEN them that you cant seek.. Look for small indications of pitting on the contacts. Loosen all contacts, sand paper / shine and reinstall / torque.
Looks like the wires are HARD WIRED to the transformer.. Only place for pitting / corrosion is on the switch contacts and the main lead for stinger / ground..
yes... dont look too close at the power switch... This guy has the green (ground) and white (hot) wires mixed up !!

Hey Steve,,,which search engine do you use??? You always seem to find these great referrences,,,,!!! Gotta know which words to use,,,,,I'm gonna open that back of the Lincoln again to look closer at the contacts on the rotary switch as I always been suspicious of it as it has always turned awful EASY when switching heat settings almost with hardly any resistance,,,,? Prolly reemove main switch also and clean contacts. This area has always been bad about corrossian on brass/copper,,,,??

I just GOOGLED "Lincoln AC225 welder" to start with... You get a lot of info / sales / data...
Then i went to YOU TUBE and typed in "Lincoln AC225 welder" ... and you get a list of how to REPAIR / UPGRADE / RESTORE... etc.... then look at a couple that SOUND GOOD to see if you can find what you want.
here is another......

It sounds like there could be some shorted windings in the secondary side of the transformer. A welder transformer is way more complex than a simple step down transformer. The secondary has inductive reactance built in, often called a reactor. It's purpose is to keep the amperage constant by varying the voltage by varying of the magnetic field in that part of the transformer. Without the reactor, it would be like trying to strike an arc using a 12 volt car battery, jumper cables, and a welding rod.

With power off (had to say that...jes in case....) open it up and clean the contacts of the 'amps selector'. yes I KNOW the movable one is 'fun', I used a thin ,very fine file for that... when it 'gave up the ghost' I got a new switch and WOW, machine was like new again....

Well,,,I did not get much done on my welder issues today as it never got above 14°,,even with the sun out most of the day,,then it couded up real dark,,almost like Tornado weather but nary a drop of water,,, Did a little work on my older arc welder in garage putting it together,,,Blew a lot of gookies out of the slot in transformer where the "amprege adjusting "slide" goes in and out of... LOTS of junk and spider webs,,,,!! Fired up the lathe and mACHINED A COUPLE OF QUICK SLIDE-IN CONNECTORS FOR THE GRD AND POWE LEADS into the box. Just need to attach the 3 prong connector on to the power lead and put this machine to work!!, I'll get back on the lincoln after Christmas,,,.

Actually 6011 rod is designed to use on rusty steel and somewhat of a "fast freeze" rod that is often used for the fist pass of pipe welding. The 6013 is more of a "fast fill". There are some companies that make rods that any buffoon can make a pretty weld with. Way back when I was in high school welding class a salesman can to do a talk and wrapped the cord of a stinger handle in a twist and then laid the end of the rod up against steel, then let go and walked away until the rod burnt out. It made a perfect weld without any human input. I can't remember what the name of the company was, although I do remember that back then those rods were expensive. |

We had rods like that 50 years ago. They worked good but had to chip a lot of slag off. Now don't weld much and use mostly wire.

The Lincoln AC225 is probably the most common welder on the planet, and I own one, used the heck out of it for decades before getting my paws on the Miller SRH-333 and CP200... but with probably 12 welders now in my immediate fleet, the AC225 is STILL here, because my grandfather gave it to me.
The problem you're having is clearly a matter of resistance in the cabling somewhere. It could be at the cable connection terminal (inside the unit) or at the ground clamp and stinger connections, OR... if there's a cut in the wire in the middle, it could have a rotten spot in the copper somewhere inside that wire somewhere.
Grab a wire, nearest the unit, bend it with two hands. Move away by an inch, bend it again. Keep flexing it 'till you get to the other end. Repeat with the OTHER cable.
If you EVER feel any spot that feels 'crunchy', cut it open with a knife, and let all the fuzzy green powder out. Then remove the cover, disconnect the old cable, thread in new cable, connect it, seal it, tape it, seal it again... then reinstall the ground and stinger clamps (make sure the AC polarity is set right ;-) ) and then clamp in a fresh rod and try again.
The "AC Polarity" joke is is an elbow-ribbing to all those who suggested Joe check the polarity of his AC-225. Those of us who weld lots are very sensitive to our polarity when using AC.

got me REAL curious !! My original , 1987ish..AC-225-S is HARD WIRED...does NOT have 'slide in connectors' nor does my spare unit or the one in the picture 2-3 posts up.
DJ if yours DOES have 'slide ins', you'll need to buy PROPER ends ( 4 pieces) to repair it OR properly modify your cables to bolt on. I have spare cables here but no passport.
A couple of pictures would really help ! I KNOW the parts ARE available.
BTW AC power does have a 'polarity', here in Canada, it changes 60 time a second. Faster then all the LGBTQXYZ crowd combined.....

Jay, every time I come up to supervise a site install, I'm amazed at how the time-space continuom warps north of the Poutine Curtain... It's quite a paradox, that my Maple-Leaf friends move so slow, but work so fast, get so much done, but still not finish... I'm certain you're right about it changing 60 times a second, but I don't think any of my crew up there are patient enough for that polarity reversal to occur, in order to take advantage of it when it happens...
Besides, it's cold outside, we should be in a pub, telling jokes, dunkn' Frites, tippin' brew and watching curlin' girls on the ice... Mebbie, when we're done, that compass will be pointing the right way to strike the arc, eh!

Hey Jay,,, My bad,,,I was jumping from one machine to the orther ,,Sorry The ""slide-in" connectors were for the the spare welder I have, It is about 50 years old and used to weld with the best of them ! It is a NCG Sureweld 200 amp AC arc welder. I figure I could get it going again sooner than the Lincoln. And yES the lincoln has those short azzed cables that I do not like,,,!! I DID check the full length of both cables on the Lincoln and are both nice and flexible,,,

Okay, so the next step: Clamp the ground clamp in the electrode holder (dead short).
Set the 225AC to lowest power setting.
Connect AC power, turn it on. let it grunt for about 2 minutes, shut power off, disconnect AC line, now feel all the cables and connections. Find the HOTTEST part, disassemble that joint, clean it up, and repeat the process on next-setting-up or two.
When you've gone about halfway up the welder's range, and there's no noticable 'hot' spot, try welding again. Clean up that ground clamp, and clean the rod grip.

I’ve had to clean the amp switch a couple times before n my Lincoln 225. My dad just loaded it up at the store and headed home when the news came on about JFK.
It really likes that TSC 7018AC.
The switch is very hard to turn on it. Always has been.
A couple years back I had to replace the stinger.
I did the ground clamp at the same time.
Funny thing, my engine driven Miller AEA does not like 7018AC.

thanks for the info, I have seen a lot of 'mods' to these super reliable units on the net...
The 'trick' to turning the switch is to push it in a bit, then turn. The pushing releases some of the spring tension, so it turns easier. Also LIGHTLY file the corners off the switch contacts, helps the wiper contact move pver the tap contacts.

Well Chit, Steve,,,I keep forgeting my honey is not here and I AM the current Boss Man Of the Place,(,hard to break those old habits,),,
As an update on the weld rod issue,,,, I did get thet older NCG arc welder going and it STILL welds like a dream! I had some 3/16 6013 and did a couple of butt welds using two plates of 1/8" plate and just looked like some dimes just rolling along, I LOVE IT!! Then I grabbed some 3/16 7014 and had to raise the heat to 120 and did the same as the 6013,,,,WOW it getting gOOD!! Then, I got some 7018 in 3/16 and just could not get the arc to start, raised the heat to 140 but was still erratic stop and go. Don't think this machine likes 7018,,,, THEN ,,I had to try the 6010 as I have a 50# box of it in 1/8 and ,,,,and,,,I'm gonna have to sell that box to somebody,,,that sob will NOT light!! I'm satisfied with the performance of the 6013 and the 7014 as they were easy to start and weld metal flowed so pretty, so am going to finish up the trailer project with the NCG welder and then get back to the LinCOLN to see to it's issues on the rotary switch, I'm almost positive it has a problem as the switch does not "Click" when switching ,,more like just slides from setting to setting.,,,??

YES, 'switch issues'.... when you see how DEEP the 'detents' are, then it's 'houston,we have a problem'.
You may have lost the spring and ball for the denent...pretty sure I tossed my old one out,but I'll have a look. I KNOW I have a spare..prewired to the transformer,the dang HEAVY transformer....

not to be critical Joe... but the smaller rod is 3/32 , not 3/16 ..... I have seen the FACTORY weld with 3/16 rod ... good when your doing 2 inch plate and have 200 amps or better !!
