Good day all. This is my first real post and I hope I am not being redundant on this question. I have an extra riding lawn mower with a 12hp vertical shaft...
The basic unit conversion is 746 watts/horsepower. 100 amps @ 12 v = 1200 watts (actually, 15 v is more realistic, so 1500 watts) 1500 watts / 746 watts/hp = 2...
Hi Tim, Roylowenthal is quite right in stating that your engine will happily run this alternator. If you plan to use it for welding, the alternator will take ...
I have been thinking about my 12 hp craftsman motor. I think I know where I can get a 140 amp alternator. I may be able to scrounge up a York air condition...
Howdy Tim, Yes, that information is missing from the site, as it's a somewhat unusual approach that I took for my air compressor. My alternators deliver about...
Hello, I'm new to the group but have been wanting to build a weldernator/amptramp for a while. Finally got going and have had a small stumble, if you can call...
Howdy Matt, A 2HP engine is too small for this kind of mechanical load. If we take a look at the maths here, you'll get a better idea of the sort of HP the...
Well, when it rains it pours. I had a little while to work on it tonight and to try out the new 5 horse motor. Got everything wired and switched on. I...
Hi Matt, It looks like you are near to getting your new welder up and running :) . Pictures please :) . Your 5HP engine should be able to manage, but will...
SUCCESS!! I pulled the alt apart and found that the damage was actually to the stator lead, it had broken. So, yesterday at lunch I went back to the...
Well still no luck. It will weld a little with the 3/32 rod, but not really. I checked the output without the cap and it ws 98 volts AC and 48 volts DC, does...
Let me add one more question, does the rotation of the alternator matter? I didn't think it did but I've been looking and am pretty sure mine is spinning...
Hi Matt, You seem to be close to success here. When welding, you'll hear a high pitch whine coming from the arc. This is the natural frequency of the...
Well, I figured out a lot of things last night and today. Yes, definately get the high pitch high frequency whistle. I figured out why it wouldn't work right....
Hi Matt, That's great news :) . Pretty soon, you'll be welding with a superb degree of freedom. You've pretty much beaten the worst of the technical problems,...
... When welding, you'll hear a high pitch whine coming from the arc, well actually it is coming from the kitchen, and if you listen carefully, you will here...
Har har dee har ;) . Ohh, Keefy Weefy :) ...... Seems to me that the foot control is best applied to the throat of the one who is whining in the kitchen. ...
... 10HP should do well. I have built two welders. One used an 18HP B&S engine, the second used a 12HP. The 18HP worked great and the motor barely slowed down....
Howdy Scott, It's great to have another welder builder here :) . Building around that nice little 12HP engine must have produced a light and portable machine....
... Yes, but I probably will not take it that far ;) I'd say it weighs about 200 lbs (<100 kilo). I have two huge mains-powered welders. An Airco Heliwelder...
... about ... Amps ... to ... wanted ... cost ... real ... Ahhh, like you, I started out with a mains powered welder. Much smaller than your machines, this one...
Hi- Someone told me about this group several weeks back-and I joined but forgot to post pics of my homemade welder/generator- until now... I have pdf files of...
Howdy Bstogsdill1, Looking good :) . I like the idea of being able to sit on the machine and have a bit of a rest, or go for a drive around the garden :) . ...
Hi there, Natchezbrown, I like the way your welder project has evolved from the open frame design to the enclosed version. When done like that, and fitted with...
... Mine was similar; based on a riding mower to become a "Riding welder". I have since made a enclosed box with wheels. The riding mower just took up too much...
