Wondering on the warranty. If the smoke comes out, Would the welder go back to Amazon or China?
Before adding the warranty I phoned the warranty company. They said send it back to the (US) company that listed it on Amazon. If they can't fix it then the warranty buys you another one. And - I expect these US welder dealers are merchants, not techies. So if they can't fix it in a few minutes by swapping in a board from another warranty return, then you get the new one. All paid by the warranty company so the dealer has no reason to give you a hard time.
That warranty company persuaded me this process is painless, at least as easy as dealing with Lincoln, Miller, etc on a warranty return.
And they said they have surprisingly few warranty claims considering we all know these are cheap Chinese welders.
Seems to me you buy the import welder and consider the warranty an integral part of the purchase cost. And figure if it, or the replacement , lasts as long as the warranty term, and assuming that all this costs 1/5 of a 'real' pro welder, you are way ahead of what a production-shop pro welder would cost.
That said, I think these are suitable for the tinkerer, the DIY'er, the farmer who needs it for occasional repairs (me), anybody who won't use it for hundreds of hours/year in a production shop. For that application buy pro gear and charge your customers enough to pay for it.
3 years now and I'm happy with my dual voltage small Amico. Another poster said he has Amico stick welders for his crew assembling carports or something and they all work perfectly in his light production application, no problems at all.
On Amazon there seems to be a lot of decent-quality import welders at very fair prices. As always, its worthwhile to read reviews and compare features, not just go for cheapest available.

Added: After posting that I saw the next page discusses buying a welder via Temu. Cheaper, but I doubt the solid warranty I described would help on a Temu purchase. More of a gamble. Temu might want it shipped back to China, very expensive and slow.
