STOP LOOKING AND BUY THIS WELDER!! BEST I'VE SEEN FOR IT'S PRICE, NO JOKE!!!!
This little dude, and I do mean little cuz its small, performs well beyond my expectations. I have only used it on a 110v 30 amp circuit with its output set at minimum 30ish amps and at a maximum 125 amps. At 125 amp it didn't break a sweat welding two pieces of 1/4" plate mild steel about 12" long together with 6013 5/32" rods. I'd say this machine is perfect for any hobbyist or weekend warrior. Only thing I cannot attest to is how it holds up to constant use. I have, however, burned through a lil over 1lb of those 6013 5/32" rods on 3 different projects over the course of about 2 - 2.5 hours and never once did it shut off as the manual says it will when the duty cycle limit is reached.I say "HELL YEAH YOU SHOULD BUY IT!!" to anyone looking for a small, portable, reliable (so far), and user friendly welder.

Awesome little stick welder!
It works great! Decent material construction for the main body housing, although the cords are a bit short and the electrode clamp that comes with is a little flimsy compared to others, but for the price and being able to weld most any SMAW electrodes it's hard to best. I got a Lincoln electric electrode holder to replace the one this came with and am considering longer cables but that's mostly just me, the welder itself does its job well.Some more minor issues, for example, no specifications plate on the device to tell anyone what it's amperage draw and such is... kind of necessary on any industrial electrical device guys.

Lightweight, portable and works good
This is a neat little welder. Probably doesn’t actually reach 250 amps as claimed, but I was able to burn some welds into 1/4 inch plate I used on my trailer for a winch plate really well on about 200 (220v). The cables do feel cheap but it’s $84 what do you expect, they work. I ran straight through about 8 rods and it never overheated. My rods don’t stick as bad as my buzz box when starting, so I assume the hot start works as it should. I won’t be dragging out the buzz box anymore, not when this little lunch box welder performs like that.If you’re looking for a miller quality welder for $84 this isn’t it. If you weld 50 hours a week this isn’t for you. But if you need a cheap welder that does a pretty dang good job and burns hot, this is the one for you.

Little power house
I was surprised at the power of this little welder. I tried a 3/32 electrode and this welder can easily handle a 1/8 electrode. Easy start ups and no loss of voltage. One electrode after another, no issue.
