Hey Amptramp crew, We recently launched projects pages and are looking forward to populating them with your creations. (We can even link it back to your...
Here's a preview of the article "Knurling Made Simple" posted on the new 'Articles' section of the ProShop Publishing site. If you wish to view it complete...
Howdy Joanna, Wow, what a great site you have there :) . It's nice to see the fine works of other project builders. I guess it's like a bug, once you get it,...
Are you on facebook? We now have a group on facebook that we can join and better get to know and intereact with the other members. there are 3 relevant groups...
What are your favorite components for converting diesels to veggie? Here are a few of ours: Heated Filter - http://www.ramcoperformance.com/turbofyner.htm Tank...
Howdy Steve Spence, This is a great subject, as fuel prices are surely rising everywhere. Here in NZ, petrol is costing about $2 per litre, and is still...
That is pretty much what the Amptramp is, combined output of 4 alternators. Dp tp the files and photo sections then read the message archives, it is explained...
... I'm with Natchez. Been through the archives, still got questions. F'r'instance, are the alternators simply paralleled? Is there any though put to how to...
Hi natchezbrown, In the Amptramp, the alternators are all wired in parallel. That is: 1) All earths are linked, through the metalwork of the machine frame, 2)...
Yup, that's the important part of the welding system. You could put as many alternators on the drive-line as you want. Just watch out for torsional stresses on...
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....
