In the second pic. take a file and knock down that lil "tit" sticken up there where you finished. If there is nothing under it you pulled out too fast. To dry up the puddle gradually raise the tungsten and you can see the puddle solidify, then break the arc and maintain gas coverage. If it is solid metal you added too much fill wire. There is also some undercut on the top side which would indicate too much amperage or possibly the need for a larger fill wire. the size of the weld (width) coming out of the joint from the right (as seen in the pic) would also indicate too much amperage.
