Spitting TIG weld makes me spittin' mad

Thoriated tungsten works quite well on aluminum, and is actually what I use for everything. (I'm experimenting with different blends currently though) Pure tungsten is "for aluminum" (green stripe). Although you can use thoriated, lanthenated, zironiated, etc etc on aluminum and magnesium with excellent results, especially with an inverter machine with adjustable balance and frequency.

Pure tungsten, when used on steel (DC) will just ball up.



Remember, the properties of tungsten only effect its performance, NOT neccessarily what material it should be used with. All things being equal, tungsten choice will NOT contaminate the work, itself, nor will it compromise gas coverage.
