Everything I see say's not enough gas flow. That slag is tungsten and all that junk around the weld is from lack of sheilding gas coverage and tungsten spit. If you're using a flow meter that reads in CFH you should be around 25 CFH on steel.. 12-15 for Aluminum. Not sure what it would be in litres.
