This is part 3 in a "how to tig weld aluminum" series. this video is about AC frequency adjustments and when to use different frequency settings.
Rule of thumb here is higher frequencies seem to help on thinner aluminum and lower frequencies help on thicker aluminum...especially for tig welding aluminum castings
This video is about tig welding aluminum on AC at 50hz and at 250hz.
there was a noticeable difference at the 2 different settings. 50hz got completed penetration and 250hz did not penetrate.
I tried to keep travel speed the same for both welds by using a motorized welding positioner turntable.

There is a lot to talk about.
things like tungsten electrodes..type and size ( i like 2% lanthanated for everything and 3/32 takes care of most of my daily welding)
shielding gases ...argon is best to start but if you begin to specialize in thicker aluminum, it might make sense to use a blend of ...
