i started on the top (tubed part) swirled it around a little to get a puddle goin at like half pedal and then brought it down to the base and kept it goin at like 3/4 pedal. i stayed more to the top so it kinda "dripped" to the bottom.
pics didnt really get it too well, but the welds kinda dip in, instead of being like a curved corner. base is like 1/4 steel and the two 90's are like 1/8inch steel and i used 2% tungsten (red) at 125amps
heres how i did it, aimed the arc at the bottom more, but it kinda brushed the side and melted the thinner stuff, but the heat wasnt as concentrated so it didnt blow through, just kinda dripped.
