SAVING an ABUSED Portable Welder from its Junk Yard GRAVE! ~ WILL IT START? ~ Red-D-Arc D300k P. 1

[@Male7709]

Your bridge rectifier is good, the reason you get twice the reading is your reading both sides. It should only read just like you tested. There are times you will need to flash your fields while it is running so that the lines of flux created will excite. Always make sure your brushes are free and make complete contact with your commutator or when you flash the voltage will not hit your field windings. Good job young man!

[@OldF1000]

You nailed it. Back in the 70s I was in test inspect at Hobart Brothers main plant. You saved me some writing ; )

Congrats on getting the welder up and running - working on wiring is something a lot of people shy away from but not you. Well done.

[@dandunlap8638]

The momentary is a low oil pressure override switch. You hold it in at startup until it builds oil pressure. If you leave your new switch on, it will eliminate the safety features for low oil pressure and overheating.

[@JAMESHOPKINSIBXCNC]

Should’ve just left it like it was., it was like that and worked fine until someone else came along and started modifying it.

Excellent video, I'm a Master Electrician with over 45 years experience but it's the first time iv'e seen someone make a cable lug out of copper tubing.👍

[@BenjiKimba]

Its a very good idea, but maybe too thin for this purpose, it maybe limited the current and burn away over time, see how Massive the copper is on the electrode holder around the cable..

[@johnhopkins6658]

There's someone else on KZbin who I've seen do it.

[@typrus6377]

​@BenjiKimba It can cause issues, especially with thin-wall, but if you need something in a pinch for testing or to finish up a job, it does the trick. I'd agree with you that it'd be best to order up the right pieces for a more permanent solution. The thing that I've seen cause issue is where you have to crimp down the section, with too thin of material it tends to fatigue fracture at that seam/crease, especially if you fail to anneal it after re-forming (prior to crimp or solder).

[@AJVAN_]

I also use it all the time since readily available ones are too expensive. And for tractor or machinery use it's perfect. Just solder the wire in and done

[@BenjiKimba]

@typrus6377 Yes, for moderate currents its okay, you can improve it by take a same piece of tube, saw it in over the lengt on one side, and shift it over the other one, also flattens the end and drill a hole in it so both can be mounted the same, even multiply if necessary to get enough copper thickness, and clamp it together.

[@gutsngorrrr]

A very nice score and a great fix. I think the temporary switch was meant to be there, as a means to power the shutoff solenoid to start the engine, then once oil presure has been built, the shutoff will remain active until oil or iver heat.

[@gordonwilloughby8793]

You shouldn't replace the momentary switch with an on off switch. The purpose of that switch is to bypass the oil pressure switch when starting the engine so the lack of oil pressure doesn't turn off the fuel solenoid when starting the engine. As soon as it builds oil pressure the momentary switch should be released and not used again until the next time you start the engine. If you use an on off switch and leave it on when the engine is running the engine wouldn't shut down if it loses oil pressure. That is also why the hour meter kept running when the engine was off. The oil pressure switch probably turns on the hour meter when there is oil pressure if it is working correctly and is connected to the solenoid switch correctly. If you do use a toggle switch only turn it on when starting the engine until it builds oil pressure so it keeps the fuel on.

[@terryrogers1025]

Loved the video! Enjoyed your repair journey. Suggest that you assemble the copper pipe over the wire (up to the insulation), then solder from the open end then crimp/drill as a last step. Much easier with a better transition between insulation and fitting. A bench vise is also a great way to form that pipe end into a lug! ALSO be mindful whenever welding when your dog is nearby. Their eyes are even more sensitive to arc flash than ours.

[@scottharmon1573]

Hey Matt if you debur / ream your copper pipe when you cut it and the wire will slide in easier and also if you heat and fill the connector about 1/3 full of solder the wire will adhere better and no need to crimp it. Enjoy your videos man. Keep em coming

[@DrFiero]

Hey! I used to work as a mechanic for Red-D-Arc about 20 years ago. In Canada. But I got shipped off to Georgia for a training course. Who knows, maybe I worked on that very machine. ;) If they're maintained, they'll run damn near forever. I'd love to get my hands on one.

[@DrFiero]

The fuel was gravity fed through the filter, to the lift pump, then to the solenoid (which IF memory serves was only used on the early models as a low oil pressure shut off), then to the injection pump. The return line off the end of the rail went... I don't remember. :( That does look like the OE engine. V2203 was newer. I have some parts for a 2203. I still have RDA STICKERS in my tool box! :D

[@DrFiero]

They're fixed governed at about 1850rpm. Loaded would drop to 1800 to give you 60hz at the AC outlet (which not all versions had). It gets adjusted by the bolt on the injector pump where that spring is.

Bridge rectifier - If you look at the picture - that one is ok. NO PROBLEM. The probe on one end feeds through two rectifiers and to the other side. Only in one direction. It turns AC voltage to DC voltage. The 12v needs to be added to the excite coil while it is turning. It must generates a field using many windings. The last two large wires on the master range switch show they were over heated in use and used much more than the others. The wire might be small to the current used generating the heat.

One thing to keep in mind when using power tools with the older engine drive welders is to use only power tools that are rated AC/DC because if you attempt to use anything with a variable speed then it will either fry the switch or burn the tool up.

I can tell you your observations on the bridge rectifier were correct. + to - will test as a diode and as you observed, it looks like 2 diodes in series. ac/ac will always test open. There's a lot more to diodes than I can condense into a comment, but you're on the right track.

[@Flying0Dismount]

The main spec you care about when selecting an alternative oil filter vs. factory specified is the pop-off pressure for the bypass valve. Most oil filter media are similar enough in mesh size that they will do a similar job in filtering crap out of the oil, so I wouldn't worry much about that; physically larger cans will be able to hold more dirt before they clog, which is a good thing, but if the bypass pressure is not the same as factory, the valve may pop prematurely, letting unfiltered oil just flow through the valve, or probably worse, it may not pop off at all and if you let the maintenance schedule slip and the filter gets clogged, it will starve the engine of oil... There is no correlation between bypass pop-off pressure and physical size (ie, just because it is the same or similar size doesn't mean the bypass pressure is the same), so you have to look up the spec for the original and the replacement filter..

[@dfross87]

Definitely worth mounting it on a trailer. My main suggestion to you for this sort of equipment is to standardise components as much as possible. Means it takes more work to set up (because you have to modify things to your standard) but it's well worth it in the end. For example, when we built our equipment trailers we chose a standard rim & tyre, standard axle and standard leaf springs for the trailers. Easy. But we also chose a standard battery, and standard air, fuel and oil filters. Additionally the filters were remote mounted to make servicing cleaner and easier. Standard fuel tank with low pressure electric pump. Replacing any drain plugs with valves and hoses that lead neatly under the trailer makes for simple and clean fluid changes. We also standardised (as much as possible) on the instrumentation and controls. Another useful thing was to make up a plaque listing all the critical specifications of that machine: fluid capacities, servicing requirements, etc.

From years ago when I used ATF to clean up gas engines, I was totally surprised at how little smoke you got running it. I used to get a total smoke screen! The higher compression of the diesel must actually burn the ATF cleaner. I think I would cut a hole in the garage door with a flapper cover so you can poke a hose through it when running engines in the shop. Wouldn't be a bad idea to have a hose bringing combustion air in to the engine as well. They can pump a lot of warm shop air through and out. Curious to see if the generator is operable as they can be the hardest part to repair and get parts for.

[@TheGWCRedneck]

15 years ago I come across near the same thing. But mine was a Hobart and it was paired with a Jeep Willy's gas engine.

The 120 volt plugs are actually fed from the generators exciter. The exciter is the smaller round bit sticking out of the back of the unit. The exciter output should be approx 120 volts. Check for a dirty slip rings on the exciter. That was my standard fix when I got a shift call out to a non-operational motor welder was to clean the exciter generator slip rings to get the generator working. This worked 99.9% of the time. Of course these welders were in use and hadn't been sitting in a field for many years.

It only had 5 resistors 3 electrolytic caps & 1 low power transistor 1 MOSFET transistor 1 diode 1 bridge rectifier ( 4 diode thing) everything checks out. Mine is 1984 & heavy "not", a (light weight switch mode) charger, so maybe its the big transformer windings it self.

[@zombieresponder]

I had previously thought all of these machines were based on the Lincoln 300, but that one may be based on the SA250. That said, I don't think any of the 250s had an option for a Kubota engine...but the 300's did and still do as far as I know. The Ready Arc variant was a really dumbed down version. It runs at one speed, where the normal version of the machine has a selector switch for auto idle(runs at lower speed until a load is detected, then automatically speeds up) or high idle(welding/generating speed). You can install parts from a standard version of the machine to get the automatic idle function. I have a Lincoln SA-250, which came from a scrapyard. It was partially disassembled, but all the pieces were there and I paid $400 for it. Mine is a 1993 model IIRC and has the diesel Perkins D3.152 engine. This engine was also use in Massey Ferguson 135 tractors, some New Holland tractors, and other equipment. One thing I can tell you with certainty is that your method of starting with the engine is absolutely wrong. The generator portion of the machine should be checked for wasp or mouse nests(which you found, eventually, and lucked out that it didn't get sucked into the armature or field coils) and shorts before you ever try spinning that motor over. Forget the engine even exists until that's done. I see you have a number of other similar videos, so I offer this advice to save you from a costly mistake in the future. I don't know about the armature on that machine, but a new one for mine from Lincoln is over $3000. Getting the armature rewound costs about half that. Field coils were several hundred dollars when I last looked. Any of these parts are easily ruined by debris that could and should have been removed before the engine turned. Again, not checking will eventually bite you and may turn an otherwise good machine into scrap. The fuel solenoid is there as an engine protection feature. If it overheats or loses oil pressure, the Murphy switch trips, shuts off fuel, and shuts down the engine...hopefully before any major damage occurs. My machine wasn't equipped with this option when originally purchased. Everything is easily available and not very expensive. I'll be adding it to my machine. The momentary switch is there to be used at engine startup. Remember the Murphy switch stops fuel flow if there's not enough oil pressure, and at startup, you have zero oil pressure, which means it also won't allow fuel flow. So to enable fuel flow, they add a momentary switch to override the Murphy switch. DO NOT defeat this with a constant on switch. Unsurprisingly, most of this information and some troubleshooting is in the manual, which is available on the Lincoln Electric website. Alternatively, you can call up Lincoln Electric and they'll probably put Bob Crow on the line to help you. A set of Lincoln replacement insulated stud connectors for the welding leads cost something like $30 when I last looked. My machine needs a set.

One your oil pressure is above 10 psi release the momentary/Murphy switch engine will run. Upon low oil pressure or high coolant temp the engine will shut down via the fuel solenoid. Also adjust your engine RPM's to obtain 120v at the outlets. The voltage at your welding leads do not correlate to the range and fine selectors directly, although as you increase the amperage voltage increases. Amperage is directly correlated to selector settings.

Wow, great job bringing the dead back to life! I got an old Miller AEAD-200LE , a somewhat smaller machine similar but powered by an Onan gas engine. Mine was found under a tarp on a ranch in the mountains and followed me home on it's little trailer. Stuck valves and a bit of other things I had to fix to get it running, so this was a neat video to see how you did a similar project. End result, we both resurrected a couple great little workhorses! I love bringing old things back to life!

This was your best video yet. I really learned alot. You should be a shop teacher.

I always like to watch the more in depth restorations etc, Like how you spent the extra time cleaning up all the connections and painting the air box. Imo the extra work is well worth it, Stuff really looks nice when you give it a little tidy up

Watched up to 14:25 and you made 2 comments about "Sheetmetal Screws". They are Tech Screws and are a Perfectly Acceptable to secure a cover of That kind. It is just you say it in a tone which demenes them. They are made for such projects, Grant it, they might not be origonal to tha machine. But So What?. Went on to watch the rest of the video. Good stuff. Enjoyed watching.
