I have another question for the other fellow tig welders, I'm welding bicycle 4130 chromoly tubing (.035-.049) using er70s-2 .045 rod. eastwood tig 200 welder no pulse is set at 50 amps. w/ foot pedal. torch it a 9 with gas lens, tungsten 3/32 2% thoriated. My welds look pretty good but I'm getting too much burn through. How do I control the burn through?

I'd try going down to a .035 wire. If the wire is too thick you have to wait around a bit longer than needed just to melt the wire. Also, might want to turn your amps up a bit so you can weld a little faster with the extra heat. Want to get in and get out as fast as you can. That has always helped me with burn through problems.

that tungsten seems huge for the amps try a .o40 goob to 80 amps dc if i remember right. I always use the smallest tungsten i can to help pinpoint the arc.
