cool, but that ---- scares me. that arc/plasma stream is way to hot. i might try this after i do some electrical engineering courses.

 

awesome. slowest plasma cutter of all time. how thick does it cut?
$260?
You can get 50 amp chinese cutters for sub $300 now.



The project is on the yahoo welding group in detail. Looks like itd be a bitch to get it running well.

 

If you use that arc stabilizer circut (part with car coil) you should be able to turn your stick welder into a tig machine that can do aluminum.

 

The guy designed it so it could be put together by most anyone with common hand tools. He did a really good job of it, too.

If you ditch the $20 GM 3-pin module for a $0.57 IGBT that's rated to handle more power things get dirty cheap. Under $100 easy, and you can scale up the capacity of the unit for very little extra. FYI, I have three sets of china plasma cutter torches, they run $25 plus ship, along with the TIG torches and welder itself, from anyone who had their Smiley 3-in-1 take a steamy dump.

The circuit is freaking simple, I'm not seeing anything beyond spark gap that needs to be fiddled to get it running well. I really like how he uses commonplace stove coils as resistor banks; you can find the real deal for a dollar at a local scrap metal facility, but that's plain crafty.

 

Hook a nignog up.
How much?

 

$100

 

lol,

How do you quote the price and then ask how much?

Read the whole quote next time.

 

Hey
Just because he gets them that cheap, doesn't mean hes going to sell them that cheap ------- retard. That and he might not be able to get more then the three he has.
Thats why I asked, so SHUT YOUR FAT ------- MOUTH because you probably read your post out loud while you type it, because your such a ------- idiot.
