watch out! I hear if you use a digital camera to take pictures of welding or the sun you can fry the CCD or lens. :ahh:

We used to MIG weld our aluminum at home in the shop. We now send two people to the TechShop to TIG weld. I love welding so much I just had to write this:

"Short-Circuit Magic"
A blaze of light behind the welding screen
A cry of "Welding!" and sparks flare up green
Flying shreds abound
Metal powder all around
A wire brush reveals the aluminum sheen.

I miss our temperamental MIG. It now spends its days sleeping in The Closet where we store all our tools. I hope it will soon be revived...

We use a Lincoln MIG with a spool gun. I don't know the wire size off the top of my head though. We bought the spool gun in 2005, after trying to weld aluminum without it. The smallest wire we could get was just too large to work with, and we kept having problems with the feed. 100% Argon in the tank.

The spool gun is much easier to work with, and much easier to learn than a TIG. The welds aren't as clean, but with enough practice, they work just fine. TIGs are great, but take a lot of skill and practice to do correctly. All of 1388's robots have been MIG welded on site at our school. Here's an example of our MIG'd 2008 frame.

We've always used a MIG spool gun. We have a TIG too, but its kinda annoying and difficult to use. A good MIG weld is about as good as a TIG weld. Some say it is weaker, but we've never broken any MIGs (We have broken 1 TIG :ahh: )

Glad to hear someone else is working at the Tech Shop. Did you know they're going national?

Yea! We heard that you guys were working there, but they wouldn't tell us what you made...
