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...

Howdee folks, I have added a couple of pics of a project that I have been developing for the past 2 years. It has turned out to be one of my more complex...
Wow! how did you get your workshop looking so clean! Will your CNC machine handle fibreglass sheet? Maybe you could make me some spare parts for my RC...
I want to build an alterntor welder. I do not know anything about changing the wiring inside an alternator to make it an unregulated one. Does anyone have a...
... wiring ... I'm new to the forum and I'm still reading all the information on building an alternator welder. It's interesting that this method of building a...
