- Hey guys, while this is not a welding video, it does have a welding machine in it! Either way, if you have 21 minutes and 46 seconds to spare, maybe you could suggest what to do with this current find. I picked this up in hopes of using the engine for my forklift but maybe that will change. Let me know what you think and let me know if these are hard to rebuild. Thanks for your support.
Recently I have been buying old engine driven welders and restoring them. I own a hotrod race and fabrication shop so it's a perfect fit for me. I build all my own sheet metal panels in house and I recently started powder coating in house so my oven is big enough to powder coat welder frames. I just converted a sa200 I am working on to coil near plug ignition with electronic fuel injection using a fabricated aluminum intake manifold that I build in house. The efi system has Bluetooth and wifi remote monitoring capabilities so a welder can check engine coolant temperature, oil pressure and engine rpm from a app on their phone and I am adding the ability to start and stop the machine from the phone.
Hi Isaac and son, definitely give the big 40 a full restoration and take us all along for the ride 😊
A buddy of mine has a Miller Big 40 mounted on the flatbed of a rather large truck that's been rotting beside a barn for at least 35 years. That'll be a really fun Father/Son project.
Crane company owes you big time. Great ad.
It ain't what you're gonna do with the welder. It's the interaction between the old man and the young kid. You can't buy memories like that. What impressed me was the interaction between you and your son as you did everything to load the welder onto the trailer. It's obvious that you and he have developed some teamwork in how you do things together.
After being a Dad for forty years I will say this. A man is lucky if he's got a good job,a good family, and a good truck. You have knocked the ball out of the park!
Tell ya a little story about one of these. Way back in the 80's I worked for a parts outfit, owner had a welding/ gas store, sold miller. They took in a 40 some guy had bought at an auction, out of a flooded mine. He'd had the engine rebuilt, cleaned it up and could not get it to weld. Short story, ended up removing all 6 diodes, and I had built a big tester to load test automotive/ truck alternators. Tested all 6 and MISSED the fact, found out later---that someone had replaced one with the WRONG polarity. So there were 4 of one polarity and 2 of the other, and it loaded the welder output and would not weld. Felt pretty good when I found that!!! ---even thought I'd missed it first time around.
I bought a Big 40D 3 years ago for cheap, ot ran but poorly, went through it and found a good radiator guy and brought that baby back to life
A friend of mine that used to be the welding tech at a community college took machines like this, waved his hands over them, and made serviceable units out of them. I turned down an engine drive that a boom had smashed that was offered to me for $35. He took it and worked his magic on it and resold if for good money. Several of us took a class that he taught to figure out his secrets. I'd think that trying to make a working unit out of this would be worth the effort. Then, rebuild the forklift engine.
I found a big 40 at a auction couple years back. Took a little bit to get it running but when it did run it was awesome!!! Wish I hadn't sold it...If you decide to get it running I highly recommend the PerTronics pointless distributor. Made my life so much easier. Mine had the Continental engine part number for the distributor I got was D41-05A.
I am a fan of rebuilding machines, if it make’s economically sense. So I would vote for rebuilding it.
I think you should turn it into a charity project with full sponsorship from elections and mechanics to benifit a trade school and definitely get Mike Rowe involved he's the man when it comes to that👍🏻
I bought an old Lincoln Weldanpower 9-G, replaced a lot on the Onan engine, carb, coil, plugs, wires, intake manifold, reseated the valves, replaced the fuel tank with an aluminum tank, fuel filter, soaked the seized inner workings of the dials with pv blaster still works today, resurface the contact of rings, replace the couple capacitors in the welding unit. Welds great and runs great. I very much like the old mechanical welders lest stuff to break. Easy to fix too.
Man I love that truck. That's a high end rig you made!
I have a 1980 big 40 that I got from a junkyard. He had it for 10yrs sat unused for 8. Rebuilt the carb, new coil and a couple of diodes and she was going. Great machines but they weigh a literal ton, 2067lbs with the axel and tongue.
I have a big 40 just like that one. Mine is a 1978. In hacked and a factory muffler. It's been a good machine. Some parts may be hard or impossible to get. Don't throw any parts away thinking you'll get another one easily
I would definitely get it running and welding. I bought an SA-200, partially burned for $200 years ago. Smoothest welding machine I ever owned. That's what I learned to weld overhead with 7018. No computers, problems were always repairable in the field. I carried an extra coil and a carburetor kit with me. Never left me stranded at a job. Scott
Howdy Issac,
From a very selfish perspective, if it belonged to me and my son was at an age which he was mature enough to appreciate it, I’d do a father and son project.
You probably will never come across a beautiful artifact as that ever again. My vote would be to bring it back to its original glory and let your son use it on his future truck.
