it is impossible to make a TIG look like that.
If I was you, I would get a small MIG for sure, or if that isn't an option, practice more before working on something you actually intend on riding, and don't practice on some thick scrap, practice on the same tube scraps you intend to weld, this way when you get the welder dialed in, you are ready to weld your finished parts.
Those welds will break guaranteed. If the rod is sticking, that means you are touching the rod to the metal. You need to start the arc with the rod almost touching, then pull back slightly. If the rod sticks DON'T turn up the heat. Turn off the welder, unclamp the rod and break it off by bending it back and forth with some cutters or something right at the point where the rod is stuck. (if you damage the coating on the rod, trash it) Then try again, remember you need to slightly pull away from the metal. As the arc starts make small "C" shaped movements back and forth and watch the pool. If it burns through, the heat is too high, If the pool seems to be puddling on top of the metal and not penetrating the heat is too low. It is pretty hard to have the heat too low with an arc, but I guess you could. Also get the appropriate rod for the appropriate application. It is on the back of the package.
Good Luck, and if you need any other pointers/help, please let me know.
