I ran a few rods on the new welder. Pretty smooth arc. Not that I have a lot of diversity in my experience, but it is about the smoothest I have used for stick. Since I am a nerd, I actually started reading the manual...I know, sorry fellow men....but I found an excerpt on Tungsten that relates to Inverter type welders. Up to now, I have only used Red and Green banded and the manual states to not use Greens. Coincidentally, I have used, broken, dipped, ground to a stub most of them anyways so not many left.
Here is an excerpt from the page on tungstens. In short, I am going to explore blue banded. My last machine was a transformer so makes sense that the newer technology might affect the process.

For welding in AC and DC consider the following types.
• Lanthanated 2% (Blue Band). Overall this is one of the best choices for TIG welding and can be used for AC and DC weld-ing. It has great arc starting characteristics, and its point hold-ing capability is excellent.
• Ceriated 2% (Gray Band or Orange Band, depending upon brand and country of origin). This is a good choice for welding with both AC and DC, but doesn’t hold up as well.........
• Thoriated 2% (Red Band) Still considered the best for DC, works ok for AC, but has been banned in many markets outside the US due to a small radiation risk posed as an alpha emitter.
Do not use the following types of Tungsten.
• Pure Tungsten (Green Band). This will create arc instability. The tungsten will not stand up well to the more intense arc created by an inverter welder.
• Zirconiated Tungsten (White Band). This was created as an alternative for Pure Tungsten for Transformer
