This is a great value garage welder for the price, it required some attention to assemble and run, make sure to get 6011 rods for this machine if you are a weekend warrior like me, me put it on I don't know what you can't do, you can weld 7018 rods with an AC welder. After a few days of trying I figured the welding isn't that hard. 20 years ago, back in the workshop, I did a little research and found out! So to avoid banging your head on the wall, get 6011 sticks and it works great!
