Stryco blade welder

I delivered a pair of minty Simpson 260-8 voms to a friend who owns a welding machine repair company Wed. (ARCO, Santa Fe Springs,
California) as he needed a couple spares. Id gotten them for $10 from another buddy's electronic surplus place. Shrug
He gifted me with nearly a dozen 12" rolls of various types of MIG welding wire pulled from machines that had bought the farm and were trashed..and as I was loading them in the truck, I noticed a blade welder laying out in his bone yard. He said someone had brought it in for a repair quote, then had never come back, and as he had no interest in it, had put it out in the boneyard to be scrapped. Since I have full rights to the bone yard <VBG> I tossed into the back of the truck.. well..grunted it in..that little basard is heavy...geeeze.
Today I remembered it was in the truck, so gutted it out and up on a work bench. Its a Stryco MF4, No. 480, probably older than Uncle Fud, a bit rusty and the paint is peeling off. Popping the top, I found everything to appear ok, except for a wire that had gotten abraded and had burned in half. Must have scared the snot out of the operator as it was one of the two 220vt AC power leads. This thing is so old that it has fabric coated wiring, all of which actually appears to still be supple and flexable. The clockworks and whatnot seem to have little wear on them.
So I ohmed the main power leads after fixing the burned wire, and found a reasonable resistance for the main transformer. Figuring what the hey..I ran a suicide cord over and powered it up. It hummed when I pushed the Anneal button..so figured something was working...
I took a couple pieces of blade stock, put it in the welder and after a bit of skull scratching and humming and mumbling, hit the Weld button. FIZZZZAAAT!..Holy shit! Lots of sparks from the blade...and sure as shit..it had welded the blade. Sumbitch!
There is a clockwork gizmo inside that apparently is the timer for the weld time..a round cam that spins around for a moment, then knocks the big assed spring loaded switch open. It took me a few minutes to realize that it wasnt working properly and was stopping at the wrong place. A bit of futzing and relubing all the working parts and violer!....it works just hunky dory. Sure makes a heap of sparks and splatters and what not when it welds a blade though. I stuck in a pair of 3/4" blade scraps and it really lights up the shop. Makes a hell of a weld though... Now I understand what the little sheet metal shield that covers the blade is for. Helps prevent your tie from catching fire or a hot one going deep into your belly button if you are making blades up whilst nekked. Might help stop a southern forest fire too, in that same situation, if you know what I mean.....hummm though it might solve that persistant cootie problem ..but I digress....
On the starboard side (means "over yonder" for those of you in Pumpkin Center) is a red button marked Anneal, a red button marked Weld, and a round disky knob with the numbers 1-6 on it. The knob does not appear to do a hell of a lot of anything other than to put a bit more or less load on the blade "force together after they are red hot" mechanism. I think. Maybe. Kinda sorta. IMHO.
Anyone can tell me exactly what that knob/dial is supposed to do, and what the suggested settings are? Im a bit afraid that if I get it wrong, the lil basard will make its very own Dr. Who style worm hole, what with all the moving clockworks and such, and transport itself to Floyds Knob or someplace. Or become a Mannshein Drive and launch my work bench to Ruddabegga IV or someplace even worse....like Oakland or Santa Monica..(NOOOOOOOO!)
Anyways..and annealing..do I simply put the clamps fully apart, or? before annealing. When they are fully apart and a 1/2" blade is resting all comfortable in there..it turns an interesting shade of blue, but never goes red. Iffin I bring them together a bit..then it will glow red as long as I hold the Anneal button down. actually In..it being on the the side and all..but again I digress..sigh)
Any info on how to operate this devilish mechanism, would be appreciated.
Now I have to go put some burn cream on what used to be a right healthy southern forest.....
Damn I hate the smell of burning hair and the tiny the screams of flambe'd cooties... The horror..the horror....

    Sounds like a great find. You didn't say what the rating on it was. The knob is an adjustment for variance in blade width. The wider, the higher the setting. Remember also that when welding up a bandsaw blade, you have a direct short back through the blade itself so a bit more current is needed to overcome that then two separate blade pieces.     Once the blade is welded, use the annealing button. According to the old "Dixie Gun Works" manual, a VERY dull red color is the desired temp for annealing brittle back to spring temper. There should be a small grinder on the front to use to grind the blade smooth Without annealing the blade is much too brittle to use. A little experimenting and practice will get results. That blade loop effect applies here also.     BTW, your event depictions get pretty creative (and entertaining) in the early morn. (therefore left intact) Respectfully, Ron Moore

Rating? None listed on the data plate, but the last time I had blades welded, the shop used one very nearly the same and he was welding 1" blades with it.

The data plate says this is an 18 amp (at 220vac 1ph) or 4KW welder.

There are three ways to accommodate different blade sizes:
1) Use fixed pressure and vary the current. 2) Use fixed current and vary the pressure. 3) Vary the current and pressure.
Control of the weld cycle may be done by a timer, either of fixed duration or one that varies with blade size, or by switching off the primary power based on the movment of the jaws as the weld upset occurs. The later method is more precise and seems to be the method of choice on some of the better blade welders.
Your welder appears to be a fixed current, variable pressure, timer controlled system. And given that it is a 220VAC it may be rated for 3/4" or 1" blades. Assuming that 1 on the pressure dial is the lowest pressure and 6 is the greatest, position 6 would be used for a 3/4" blade and 1 for a 1/4". When the pressure is correct for the width blade there will be minimal sparks and an even upset along the weld. Experiment with a 1/2" blade and you'll find the "sweet spot" pretty quickly. Where the pressure dial winds up for a 1/2" blade will give you a good idea where other blades need to be welded.
In my experience with home made welders (I've built four) a large shower of sparks indicates an excessive current/insufficient pressure relationship.
It is really important the the ends of the blade be squared off and match before welding. This is best done by flipping one end of the blade, holding them together and grinding both at the same time. Ground this way any error when grinding will cancel out when the ends of blade are oriented normally in the welder jaws.
It sounds like you may have never used a blade welder before. And if that's the case surely one of your clients has one and an experienced tech. It would be well worth your time to watch someone weld a blade correctly. You'll see what a proper weld looks like and will be able to "dial" yours in.
FYI: Stryco still exists and makes blade welders. There's nothing on their site (http://www.micro-weld.com/stryco ) about older models, but you might try contacting them for info on this one.

Normally annealing is done with the jaws open. And it is really important to shade the jaw area so that you can see what's happening. The guy that taught me used to turn the lights in the vicinity of the welder off and use the built in work light on the welder for setup and turn it off when annealing. In a darkened area you just barely want to see a glimmer of dull red at the weld.
The test for proper annealing is to flex the blade at the weld. If it breaks it wasn't properly annealed. Note that it isn't necessary to be able to bend the blade back on itself, although a fully annealed weld will survive this. A modest bend, say around 90deg, without breaking is good enough.

I don't know anyting about welders, but I am amazed at the odd bits of Science Fiction that you toss about. I haven't thought of Mannshein Drives since Highschool. A lifetime ago. No I am have to track down the Grimes series. I think machine tools would be a cheaper hobby. Terry

I'm not familiar with this model. I have used a Do-All built into the saw at work. It is a fantastic welder, and produces a weld that outlasts the rest of the blade, and with as little flash to be ground off the weld as could ever be possible.
I lucked into a German blade welder on eBay. It is not quite as good as the Do-All, but it does work. More sparks, way more upset and flash, so it takes a fair bit of grinding to get it back to the same thickness as the blade. Some of these welds last a long time, some fail after a few minutes of cutting. So, I'm still getting all the settings right.
But, anyway, the welder I have has a multi-position knob that sets the weld current, in about 6 steps. It also has a knob that sets the jaw pressure for welding or annealing (2 pos). It also opens the jaws about 1/4" wider when in the anneal position. Both welders can easily get the blade up to dull red in about 5 seconds when annealing. Only the very center gets red, as the jaws draw heat off at the sides. Both of these welders, as far as I know, use a mechanical latch that allows one weld cycle until the jaws move together a certain distance. You then hold the weld button until the weld has cooled. If you take your finger off the weld button too soon, the jaws pull the weld apart. So, they don't "time" the weld, they zap it until the springs "upset" the blade.

    Its a trap Terry. First he helps you start loading the truck, then he points out a "good one" the next thing you know, it's dark and you haven't finished the book, and there are three more on your knee, and "how did it get to be election day already?" Rogue librarians are going to hijack you and your cargo, and you'll never be heard from again. Put to work chipping away in a federal quandary....

I will only have to take 20 kittens, great, I will be out the week beteen Christmas and New Years. Right after I win the lottery. Only one little problem, I don't play the lottery. I figure that not buying a ticket only decreases my chance of winning by a very slight amount. Now if I could find a winning lottery ticket that would be cool. Not imposible, but unlikely. A friend was layed off about 10 years ago, Christmas was lookng grim. His young daughter picked up a "scratch off" lottery ticket spent the entire trip home looking at it, so my friend and his wife decided to relate how bad a choice buying lottery tickets was. Explained odds to her, As they arrived home, she commented, somehing similar to, know that winning is rare, that you stand a better chance of being hit by lightning, butif winning tickets are so rare why would someone thorugh a winner away. Her mom, assuming her daughter had misread it, asked to look at it, and freaked. It was a winner. 25K. After the moral debate what to do with the ticket, after all how do you find the original purchaser, they decided to wait a week or so to see if any news stories about lost wiing tickets ran, and when none did, the decided to cash it and put it away for their daugthrers college fund. The dauhgter, a mature 8 years, argued that her dad should use the money to get some addtional training. That she had 10- years before she could go, but her dad, and the family could realy benefit from his going to school. He got a AA degree, a much better job, and the daughter started college this fall. So you can win without playing, but all in all I would prefer to set my money on fire and watch it burn as to waste it on lottery tickets. This time of year the burning money would supply a little warmth. So as soon as I find a winning lottery ticket I will be heading out that way. Maybe we could combine our respective book collections and start a"really big" library, Terry

    I thought so. Gunner hands you a "interesting book". Then while you are distracted by that, he uses arcane Buddhist Gedi Minds tricks so you don't notice him emptying boxes of books, and filling them with cats. Then he sends you on your way, and when you get home, there you are with a herd of cats, and a bunch of books he didn't want: Tropic of Calculus, Great Buddhist Accountants of Belgium, the Collected Speeches of Albert Gore, The Joy of Sox, Ignorance for Dummies, and Breaking Machine tools for fun and tax write offs.     Tricky people, these renegade Buddhist Furrballs.

I use T1 plate for back stops, and normally use 1/8" aluminum plate for leveling via stacking.

Hummm it may have been a chip off the old block so to speak.

I wonder how much that check cost them to process?
