The two new Everlast Typhoon TIG models have Independent AC Amplitude Control (EP/EN), as well as various waveforms, which I believe can be assigned differently on each polarity.
The new Everlast Typhoon units are actually more feature-rich than even the Miller Dynasty units, since the Typhoons also have Advanced Pulse/MIX TIG (which uses AC and DC to weld aluminum with greater penetration). Even my 210EXT has the Advanced Pulse/MIX TIG feature, which does give the 210 amp unit the ability to weld thicker aluminum than without the feature.
So, yeah, Everlast may be a little late to the party with AC Amplitude Control, but they've made a big splash now that they've agreed. I mean, you may know that for the longest time the Dynasty 200 and 350 models hobbled those unit from allowing the AC Independent Amplitude Control feature, unless you paid an extra of about $500 for a little SmartCard option with a few lines of "proprietary/patentable" computer code to enable the feature. But, Miller finally stopped doing that on their latest Dynasty models.
Here's a short video clip of a new Typhoon 230 doing a stainless exhaust.
