well if you have to tig weld it so be it. it's way to hot, you are moving way to slow; because of the 1/16 th rod. you don't need 200 amps. your feeding of the rod is erratic but that is to be expected given the fact you must be feeding it like crazy. look at that HAZ; the one that hasn't been brushed out, it tells the story. the only reason you would be tig welding this things is either for practice as in your case or you did not have another type of welder besides tig. good luck. ps you only need a 3/32 tungsten and rod to do this job.
