uh,...Ok just for the record when you stick your tungsten that badly you should grind that spot out. you now have what is call an inclusion.aka a foreign material in the weld. can cause a crack to form. also, he has a fan blowing on his weldment. at the very least he is removing his shielding gas which guess what? can cause perosity in the weld. doesn't give me the warm fuzzy about the quality control in the factory.

Except the fan is obviously blowing away from the work
Ya a fan is a bad idea for cooling the part too quickly as well.
Get a CNC machine.
You have no clue.
