Impressive. I imagine every single weldable object in his is now welded to one another.

this is a really great hack and what I love to see here on HAD.

if there was a rating system in place I’d give it 5 stars…

that reminds me
HAD uses wordpress no? why not add in Ajax Star Ratings, there’s no plugin but it’s pretty easy to add to WP.

that way people can click their like/dislike of an article as opposed to voicing it, and the comments might be more on-topic.

@Satiagraha

How about 20v at 3 farads = 600 joules….I’m trying to figure out if you are trying to be funny or are just plain stupid.

Nice welder!!

How is this a 600 joule cap? 3 farads at 25V means 1/2*3*25^2= 938 Joules. Granted you can only get out maybe 600 joules before the discharge pulse becomes long.

OK, beautiful job on the spot welder, but the wire diameters listed in the video are completely wrong. A strand of wire one tenth in diameter (0.0001″) would not be visible in the video. Besides which, that diameter is one third the smallest Brown and Sharpe wire gauge (60 AWG), and the whire show is far, far thicker.

I love the fact that he used a PIC instead of an Arduno :P It’d be nice to see some source code for the PIC and also what language he programmed it in and what compiler he used.

You know, we never did see a writeup for the spot welder’s power controller…

This is not a hack. There is no arduino and it can’t be controlled by twitter.

@Marvin: Well he knew that you were watching, so he chose the music appropriately.

Nice Project, but why is there always some gay music?

I’m wondering what kind of life those audio capacitors get (1F+), I don’t think they are like regular electrolytics with aluminum plates, but I could be wrong…

Well the title is a bit off

DIY Lincoln welder conversion

it’s not a conversion of a Lincoln welder, it’s a conversion of a plasma cutter into a DIY welder. Or maybe just a plasma cutter _case_ into a welder.

Everything awesome except the title.
