I have one I bought last year to Weld up My rusted through cracked Rear Cross Member.

I did not have time to learn to use if properly and did a whole lot of grinding and re-welding but that Welder saved the Car from the Junk Yard.
I could not have done the job with My Lincoln ARC Welder.

Since then I have used it to make to Weld a small Fence made of Electrical Conduit.

In My particular case what I leaned is that I can weld OK with it as long as the object is laying below me and I can see the arc clearly.

In cramped quarters where you cannot see the tiny arc and over head welding were extremely difficult for me. Being more used to the ARC Welder I have trouble getting used to the wire automatically coming out and the coordination needed to do a good job.

So while this particular welder has limited uses it has more than paid for itself and I like it because it is convent and it plugs into your normal House Hold Current.
My ARC Welder is 220 Volt and that means I have to bring the Work to the Welder. With that little Flux Core Welder I have used Extension Cords and can work anywhere on My Property.

Assuming it keeps working for a reasonable amount of time I am happy with the purchase.
