  1. There's plenty of them out there that need fixing. The folks that use welders usually aren't the ones you want working on welders.

  2. I was thinking along those lines myself. It is extra work to understand what's going on. But sometimes it more work to not take the trouble to figure things out.

  3. Carrying lots of current isn't always a good thing.

  4. It certainly has. That's why some of us are no longer participating too. When these scumbags shadowbanned me in 2020 it changed the way I did things. So now I treat this site like the cheap whore that it is. I ain't liked nothing since either. If you don't like it then tough shit. Let's go Brandon!

  5. Yeah but he put a fuel pump on this machine.

  6. PCB sealer is called conformal coating. There are articles about it on the net.

  7.  @LanceMcGrew  let's hope so. It's where those connections go that's a concern though.

  8.  @ionracer24  it never hurts to try.

  9. That's what the circled marking is on old tombstone welders. It's the pipe thawing setting. I guess the circle is the cross section of a piece of pipe? It's at the 75. Past that there's no special attachment that I know of. You just hook it up and go. I don't think it is a recommended technique today. Newer models don't have the marking.

  10. Electricity is easy as P=IE That's Ohm's Law BTW. A bit of electric humor. Understanding what that means is a big part of it though. Keeps you from blowing stuff up.

  11. No.

  12. I think when he hooks that new board up it's going to blow sky high.

  13. That looked like EDPM form flash to me. A pretty big piece of it though.

  14. Me either.

  15. It depends on what's across the diode. That board is hooked up to a solenoid so one of those diodes is across the solenoid as a flyback. Now disconnected you're OK. But there's times when that's not going to be the case. Although you could test the diode then using high frequency.

  16.  @Flowtester1  the problem we're seeing here is the human factor. Someone already monkeyed with that board. When people are involved then all bets are off. Because people can do anything. They could have taken parts out and put in different parts backwards. We've no way of knowing that now. Though often boards are marked. Still the parts themselves could be completely wrong. We're not seeing things in an unscrewed with state.

  17. He could but it'd have to be all tubes then.

  18. The board traces is the fuse.

  19.  @MayaPosch  small resistors are the same thing. Incandescent light bulbs are their own fuse too. It's actually fairly common to make protected circuitry without specific fuses but rather fusable elements.

  20.  @MayaPosch  you might get a little flame up but no fire. Not every fuse is going to be sand filled. A thermal fuse will never be fast acting. There's always a trade off between cost and performance.

  21. You have to leave the anti-theft POS camouflage on it. That's a special order option you can't get today.

  22. The less that like it the less that'll try to lift it.

  23. Inflation is just transitory!

  24. You're clearly not a fan of classic Frankenstein. It's alive!

  25. Here's to hoping just swapping in a different board fixes things. I'd still test for shorts before powering things up myself.

  26. Welding space ships is what made metallurgy what it is today. That's when it got real. Before then the reputation of nations wasn't under intense international scrutiny. So the stakes weren't quite as high. Although it all got started with train disasters. The space age just took it up a notch to where we are now.

  27. It is called a bodge job.

  28.  @johnfisher7143  the paper filter thing is a known issue. When you're gravity feed you're supposed to just use a screen. But it is great that it is working for you.
    1
  29.  @macgvrs  you can get away with using a paper filter with gravity feed. If the filter is porous and your fuel is clean and there's adequate head pressure from the tank to the carb it should be just fine. But that's a lot of ifs. If ifs and buts were candy and nuts we'd all have a Merry Christmas.

  30. You never have to let the smoke out ever though. You can always limit the supply current or make sure the load is not shorted. The magic smoke never magically releases. It's always for a good reason. But when I build mains powered circuit I'll often remotely power them on the first test.

  31. Yes it is. Dead and buried.

  32. I've had blind dogs. They generally do OK for themselves. Really it can be a benefit. They don't bark and chase everything they see then. They still love you that's for sure.

  33. Taryl likes crollers better.

  34. My guess is the solenoid is fried and it's what's blowing the board out. Or there's a short to it. Though the PCB might be tracking? Once a board cooks once the charcoal can keep conducting.

  35. Hey NASA were the douffeses that launched out of spec. It wasn't the manufacturer's fault it was that cold that morning. That's what caused the accident. They didn't say it'd work in freezing temperature.

  36. There's no guarantee that'll fix anything. I'd bet the fault lies in what that board is driving. So you plug another one in and it'll do the exact same thing. Then you might begin to suspect there's deeper seated issues.

  37. Wes' Z bends are fine.

  38.  @dougparker4802  from what I've seen of it the tool just looks like a rod with a slit cut in it to me.

  39.  @dougparker4802  you are right about me missing the pun. Perhaps it just wasn't as punny as you thought it was?

  40. I try to weld as little as possible myself. Generally welding is a crappy way to do things. But sometimes it is the proper process to use.

  41. Fire it up!

  42. Brick and mortar is dead except for bulk sales. If they can't sell it by the pallet they can't compete. That's reality today. Nothing anyone can do about it. What good does we can order it for you do for me? I can order it for myself.

  43.  @ericpaul4575  that would be difficult to do without a schematic.
    1
  44. Yeah that'd only cost a couple hundred. Each of those big cans costs a minimum of $5 a pop. Then there's shipping. Those suppliers are going to bend you over for the maximum amount there.

  45.  @willemvantsant5105  a few PCBs never hurt anyone.

  46.  @coreybabcock2025  you'd be right about 2% of the time.

  47. Their soldering may be fine. Their rework could stand for some improvement though. Old crappy solder is old crappy solder. So job 1 is to remove all of it before you resolder a joint. Reflowing it isn't always a good idea. That solder was gray and powdery. That's lead oxide. It's not something you want in a solder joint.

  48. They always run the best right before they blow.

  49. The board may not work after he hooks it up. If there's a problem in the welder that's frying the board. Like whatever that board is controlling is shorted out. Likely a solenoid.
