lets talk about mig welders??

I have a Miller 135 mig that's been great for the last 20+ years. Reliable & consistant. I've only ever had to replace consumables. I have welded body metal as well as mild steel tubing for a roll bar. I just turned up the heat & beveled the tubing edges of my joints for better penetration, (made a few welds on scrap tubing 1st to get good penetration) & was fine. If I was doing it everyday I'd opt for a 220v 175-200 amp unit.
Eastwood welders IMO are junk!! I went to a welding seminar at Eastwood 2 weeks ago & their welder (looked almost new) stopped working after about 5 min of just running practice beads on 20ga steel. They rolled out another welder & that one didnt work either!! It felt very cheap & flimsy compared to my Miller & with the problems with 2 welders I'd stay away! They even admit they are made in China to save manufacturing costs!
Don't waste your time & money on flux welding. The welds are not as nice & your limited in what you can do with it. Not good for body reapairs.
