Lincoln 225 "Buzz Box" AC/DC welder Rejuvenation

[@JK-rc8qs]

Great video! I love the restoration of a simple machine that most would never consider.

[@shopdoc]

This was a nice little welder and honestly I couldn’t tell the difference between this one and my Idealarc when welding! Great welders for cheap!

[@campbellpaul]

Those are the most practical welders ever made (for anything less than metal build-up or air/arc carbon gauging). Nice job, Chris!

[@jddeville7587]

love this I snagged this welder from work and just started to clean 'er up :} except mine has no wheels yet

[@shopdoc]

Great little welder! The wheels do help when moving it around the shop so definitely try to remedy that.

[@bigfootandbananaman4746]

Great find! That looks like a fantastic welder.

[@shopdoc]

Thanks! Yeah I think it’s pretty sweet! Sold it just a few days ago.

[@mrclay1964]

Great job, nice video. I have 3 of these welders I redone

[@shopdoc]

Very nice! They are a lot of welder in a pretty small package!

[@corbana4743]

About to buy the same exact welder for $150 . I have an old Linde 230 a beast of a welder but it’s just ac, buying the Lincoln for the dc option

[@shopdoc]

That is a really good deal for a very good welder in my opinion.

[@MadRhetorik.]

Nice job! I bought me an old buzz box Lincoln for $50. I’d love to do what you did here and totally rejuvenate the old gal.

[@shopdoc]

They are totally worth it! I have a very high regard for these old welders for a good reason.........they just weld beautifully and they are bullet proof!

[@joe-yl6io]

Very nice job!

[@chrisrageNJ]

I just converted an AC buzz box to AC/DC, I'm about $60 into it with the rectifier and jacks/plugs. I made a post about it on r/welding on Reddit

[@shopdoc]

Fantastic! I do not have the know how to do that conversion but $60 would be well worth it!

[@Tdawg46-dd2wb]

Thanks for sharing. I have this welder and the polarity selector switch is very hard to move. Any advice on how to free it up without completely removing the top shelf (choke and rectifier)?

[@shopdoc]

If you loosen the top back shelf you can apply some dielectric grease to the terminals. It made a huge difference with mine. Mine was so hard to switch I thought I might break it. Lubed it and it switches like butter!

[@victorazukas4344]

Knob replacement how is it done

[@rogermorrill4700]

I was told to shut the switch off before changing settings so you don’t burn the contacts!

[@shopdoc]

Unnecessary according to instructions and my experience. Just don’t strike an arc while changing your settings. Thanks for watching!

[@Coxfame]

Hey there, I own the 225 ac version , I didn't know they make ac/dc on this type. If I have to choose which one would you recommend? I am a DIYer. Not a pro.

[@shopdoc]

The ac/dc version is better. DC welds much smoother and better arc quality and allows you a greater range of different types of welding you can do and welding rods you can use.

[@patrickhenigin4805]

I had an old A C that I bought 1992. It was old then. I went searching for another when the selector switch broke. I lucked across an AC/DC unit with rotten leads for $100. Ooohhh it is so much better! I work mostly 7018 with positive ground, and my skill has way improved. My welds almost look like actual welds instead of something off the floor of the chicken coop.

[@bc6982]

Excellent video! I just bought a Lincoln welder just like that one, but it looks terrible. The cooling fan does not work, it spins freely but just hums trying to spin. I am going to replace it with a flat, square cooling fan for less than $25. Lincoln wants $100. I was wondering if the cooling fan should blow air up or down?

[@shopdoc]

I honestly cannot remember now. I would research it a bit. It may not be that critical as long as air is moving.

[@bc6982]

@@shopdoc Thanks for the reply.

[@BillCyr-w8y]

I have a Lincoln ac dc arc welder. The knobs turn very hard. Will dielectric grease help it u think?

[@shopdoc]

Yes you’ll need to open it up from the back and then lightly clean the contact point on the back side of the dial with some scotch brite or steel wool then use dielectric grease and you’ll be shocked how well it’ll turn!

[@roberteast4160]

I have an Lincoln electric ac-225 glm. Used it a few times but never worked great. So i took it apart and found 2 wires at the switch loose but nuts was not back off just loose, but when i went to reinstall the cover. Found a loose wire with a eye let connector on it. It comes off the transformer ( windings). It's a hot wire when it is plugged in. Short wire so it can't go more than the switch area. Please any help, driving me crazy.Thank you.

[@shopdoc]

You should have a wiring schematic inside your unit, that will tell how it should be wired. If yours doesn’t have the schematic then go to the Lincoln website and you can find it online.

[@roberteast4160]

@@shopdoc wiring diagram is a little fuzzy. Lincoln electric only sent me owners manual. Thanks away
