Yeah, too much data transfer and they shut you down! Its free so I won't complain too much. I chose tig over all other joining methods because I am better at tig than anything else. I know tig is supposed to be the hardest welding method to learn but I found it surprisingly easy. Besides, I just like the look of a good tig bead. If you are planning on building a frame from scratch remeber to triangluate the frame to keep all member in compression/tension. I should have angled the seat tube towards the front instead of angling it back like the front derailer tube. I am doing that on my next recumbent.
