I just bought the mig 175 today. After some modifications to the cart to allow the welders side cover to open, I was almost ready to weld.
I bought a roll of Flux cord wire and away I went.
The machine works very smoothly. Good penetration. I see no reason to spend twice as much for a Miller or Lincoln. I hope to get a gas bottle for the mig and also some 100% argon to try the spool gun on some aluminum. Over all a great buy, but the cart is so so at best. The may be made in China, but what isn't these days!! I'll bet miller and Lincoln has non USA parts, so save you money and buy the Eastwood.
