You're welds appear to be overheated and contaminated. Make sure to clean the material of all mill scale and dirt/residue before welding. In a few of the pictures, your tungsten looks to be sticking out way too far causing you to lose gas coverage. The bead is inconsistent and lumpy.. you really need to practice laying down a consistent bead without overheating before welding the real deal. Practice, Practice, Practice

I noticed you're using magnets near one of the welds also. I dont know if you experienced this, but in my experiences this will cause an erratic arc and it makes it very hard to even get a decent tack weld, much less a full bead.

I see some gaps in the fitup of the tubing also. This will cause you a lot of headaches especially when welding .035" wall tubing. It makes it hard to get a decent bead, and it makes it very easy to blow a large hole. Try and keep your tubing fitup very tight.

Im not bagging on you, just some constructive criticism. You gotta start somewhere and weve all been there before. Good luck with your project.

I got magnets on fire, and made good amount of holes.

How do I know overheating?
and ye, I forget to clean stuff before I weld.
