Buying a Tig Welder & Taking a Class**

The weld pattern looks good, nice coining and a pretty consistant pattern.

But I'd be a little concerned about the edges, they look like they're undercut in a few places, which does not make for a strong weld. The weld shouldn't be concave, it should be a raised bead, especially on the flatter, obtuse intersections. Obviously on the acute angle intersections you'll still have a concave bead, but it shouldn't cut into the plate.

Either add more fill rod as you go, or reduce the temperature slightly and slow down the speed you're laying the bead down at. You're moving the puddle faster than you're adding filler.
