What?

The 210EXT has a 60% duty-cycle at max amperage, which is outstanding!

I mean, here's a duty-cycle shootout video that demonstrates that Everlast's 60% duty-cycle rating for the 210EXT is actually quite conservative, too.

I've owned my 210EXT for over five years now. Love the price and value, the digital interface, memory function, added Triangle waveform for lighter aluminum, etc.
