I ran a few short beads tonight, trying alot of different things, everything from torch angle, to torch speed, to torch motion, filler timing, and what not just to get a feel. That's all good and well, I'll keep doing this to get a better feel of things. However, one thing that seems to happen every time is a reverse crater (mountain?
) as I terminate each run. I don't know if I'm backing off on the power to slow, or to fast, or what. As I view some videos online, I don't think I'm to far off on the timing as I ramp off the power. It's the opposite of what I get when I'm TIGing aluminum, with aluminum I almost always get a crater that goes down into the base metal pretty deep. But on steel, I get a mountain. I suppose the mountain isn't bad structurally... ? But I don't like how it looks.Metal is 1/4" mild steel, 1/8" filler rod, tungsten is 2% lanthenated 3/32" and Argon at around 12CFH with 10 seconds post flow (I need to look at the gauge again, to see what it's set at, but that's what I think I remember setting it at when I set it up last time)
