Dual voltage usually carries a premium. The 110V-only boxes sit at the cheap end of this set, and the price steps up as soon as a machine accepts 220V. The DEKOPRO is the exception: both voltages, a 160-amp ceiling, and a price in the same bracket as the single-voltage minis.
What the second voltage buys is headroom. On a household circuit it runs 3/32 rods comfortably and will push a small 1/8 rod if the breaker agrees; on 220V it has run 1/8-inch 6011 and 7018 without complaint. That is the difference between a machine for sheet metal and one for a gate frame. The hot start helps too, since our first arc came on the first rod rather than the fifth, and the display stays legible with a helmet down.
Longevity is the part we cannot sign off on. This is a budget inverter, and the failure that shows up is a board that still powers on but will not strike an arc; the machine looks fine and is not. Buy it where returns are easy, keep the receipt, and work it hard in the first month rather than the sixth.
The carton holds the machine, an electrode holder, a ground clamp, a power adapter cable, and a brush. No helmet and no rods, which is the usual omission at this level and worth remembering when you add up what a first weld actually costs.
Bottom line: The one we tell most people to buy: it runs on the outlet you have and the one you may add later, for barely more than a 110V-only box.
