Well that makes sense!
If you are mobil any of the little inverters... Miller, Lincoln, Thermadyne... that provide 200+ amps Which ever vendor has the best SERVICE in your neck of the woods..... Really, all three of those brands are winners.
I discovered that Miller Dynasty 300 is a really good stick welder too.
If your in the shop environment.. The inverters are still good... But if you are on a tight budget I like Miller Synchrowave 250
