2 Practical Examples for AC TIG Settings
This is gonna be a really quick video. I’m just trying to add to the conversation from the previous video about AC frequency.
So in the previous video, I got this piece of eight inch tubing, 070 wall, that’s not quite 2 millimeters. Put some lines on it, put it in a positioner. Propped my hand on a stand. And once I got the travel speed kind of figured out, where I keep it all the same, try to get me out of the equation, then I experimented using 50 Hz. That was this right here, how it was penetrating all the way through with no problem. And then I didn’t change anything, and increase the frequency to 250 Hz. No penetration. Got a narrower bead and a higher-pitched sound, but that’s about it.
