thanks lin
i have one that i've build but it's not got the right burner, i'd try to make one (venturi burner) but i've done something wrong, it's got to much orange flame, my mig tip may be to big, it's a .45 i may need a .25 in order to work right, how can i tell when i get to 1600-1700 degrees? maybe by color?
thanks for your time
