Whahooo! What a blast, this is my first time ever welding.. I am making stands for my retail xmas tree business for use next year. Using 2 inch angle iron and 4" steel piping, and a cheapo wal-mart arc welder. Max size 5/16" rods, so its slow going, but man, this is fun stuff! I can't wait to buy a bigger better machine and start new projects!
