What does a Miller Dynasty 200dx, Lincoln Invertec v205t, and the new Everlast 210 ext have in common?
They are all small portable tig inverters with similar features.
AC balance lets you adjust more electrode negative into the AC wave to get more penetration and lets you use a tapered electrode for welding aluminum in some applications and that can be helpful.
AC frequency focuses the arc more and allows a more pinpointed arc.
All 3 of these tig inverters offer AC balance as well as AC frequency adjustments and a whole lot more.
Why would someone want a small tig inverter in the 200 amp range anyway?
Because a 200 amp tig inverter is capable of welding all kinds of projects like home built airplanes made from 4130 chromoly, bicycle building, tool and die repair, general fabrication, food service repair work on stainless steel kitchen equipment, boat prop and boat repair work, and all kinds of other jobs.
And….they use very little power. A 30 amp breaker is usually all you need to get full power out of a small tig inverter and it hardly makes any difference on you power bill.
And… the footprint is so small …and it is so light that you can mount it on a shelf above your heat to save shop space….thats what I did with my Miller Dynasty 200dx and it was really nice to save the shop space.
