Primeweld has a 3 year warranty. Haven't needed to use that but that was one of the reasons I picked it. I actually bought the basic plasma at first then cancelled my order and got the tig, arc, and plasma cutter. 500 bucks, no ragrets. https://www.amazon.com/gp/product/B01AB2U0XS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I have used the plasma a lot and the ARC is great too. I think the inverter technology does well for a cheap price point vs expensive machines of old. Seems just as good as the miller machines I learned on in community college 15 years ago if not better. Picked up the stuff to learn tig but haven't tried yet. It's also survived me hooking up stuff wrong/not noticing if the ground has fallen off.
