Poor warranty and Chinese made. I would walk away. For the same $$$ you can buy the Auto Arc 130 which is made by Hobart and carries the same warranty that Hobart welders have. Here's the Auto Arc 130 for $327.21:
(notice this one doesn't include the regulator and hose but is a true mig welder, not just flux core) Amazon $406.29
and TSC $399.99 (online only)
has the Auto Arc with a regulator, cart and helmet.
The reviews are great
for the welder, pretty bad for the cart (mainly screws don't hold well, but.....ya got a welder!) and, especially the cheap helmet, but a decent auto darkening helmet doesn't cost too much. These welders are warranted by, and parts and service are available from Hobart.
The Hobart Handler 140 has a very
good reputation and can be bought for $499.99 at TSC. TSC also has the Hobart Handler 125 for $369.99.
In my opinion any of these, as well as others from Miller and Lincoln, would be a much better investment than a welder from China that would be hard, and probably impossible, to get service/parts for.
