Yes, it made a big difference in starting and holding an arc. It probably weighed 30-40 pounds or more. I have a bare laminated core from a big transformer...
... Sorry.. I hardly remember posting that msg! I was browsing some small engine sites. I may have used 'Chinese' as one criteria, don't recall. GeoB...
Greetings Friends- Updates: 1. I removed 7 inch drive pulley and installed 4 inch drive pulley 2. Removed field coil resistors- run full battery voltage to...
Howdee Garry, I have found some of these little engines here in New Zealand. At the low prices listed, it looks pretty tempting. Take a looky here: ...
Another update:  I made and installed the ATWR and I think this thing now makes welds as pretty as something you would pay for in the in the store.  ...
... Many use a resistance from 12V to the field. Usually 1 to 20 ohms. Have seen people use a rotary switch to select various combinations of 1 and 10 ohm...
I use an old auto headlight switch, power the switch with +12 VDC, hook dash light terminal to one side of field. Pull headlight switch on to activate welder,...
So you want to hook up a big alternator to a one lung engne and don't know how much "oomph" you need? 1 HP = 746 Watts at 100% efficiency. The best drive belts...
Hi-  Someone here can tell you how to do it- you need to regulate your field coil current. I just run mine full battery voltage and if I weld something...
There are a couple of files on http://tech.groups.yahoo.com/group/DIY_Generator/ on field control. Steve Spence Renewable energy and self sufficiency ...
We had a great time at the North Country Energy Fair. We had about 20 people attend our "DIY Solar class", 10 at our "Make your own biodiesel" class, and about...
Thanks everyone on the quick responses. I got a lot of information given to me. I have given it some thought and think that the "headlight dimmer switch" is...
I have a picture of dual alt's on a small engine at http://tech.groups.yahoo.com/group/DIY_Generator/ Steve Spence Renewable energy and self sufficiency ...
Hi Tim-  I never did get around to checking my current output and I dont know what my alternator ratings are (but they were the 2 biggest old double v belt...
Howdee Brad, It looks like you have created a mighty fine welding system :) . Working with electrodes of that size ought to allow you to build perty much...
... I have not noticed my alternator getting hot. I think it has to do with airflow. Mine is mounted on a plate, not out in the open. It has an internal fan. I...
Hi Steve-  I did notice that when I switch them on, the engine loads down even though they are not being used....I bet you are right. When they are on and...
Hi Scott- Â I have the factory alternator fans that are on the pulley and I am bolted to a mower frame with the alterantor pulleys and fans sticking through...
... I added 60,000uf on my Miller ;) It depends if you have a reactor. If not, then you don't want large caps as it will mask the internal inductance of the...
I have been reading that some use either capacitors or a homemade arc stabilizer. I think the capacitor would be the easiest to use. Looking on the net I have...
... Many use an old microwave transformer: http://www.instructables.com/id/STATUZYFEAHE9EG/ I made one using about 4" of 1.5"ID iron pipe wrapped in a steel...
... I have a single 200 amp. Gets about 140A with the pulley setup I have. I would say a few hundred uf, have seen people use 470. Needs to be a heavy-duty...
I just uploaded a drawing of what I want to build. I hope I am not making this overly complicated. But I just want to be sure about everything. The photo is...
HI Tim-  I wrapped jumper cable around a motor stator- Mother of all Toroids- managed 18 turns of wire to fit. I used what I could find on hand. regards, ...
