I just bought a brand new Millermatic 140 welder :D. I'll have it Wednesday. I was just gonna borrow my dads Miller 250 for this car, but it's too big to lug around and It's kinda hard to adjust and weld sheet metal with. I'm also gonna pick up a miller spot welder for this project... I can weld about 50% of the car with it and it will look factory. My Dad has always wanted one and so have I, so this car is the perfect excuse to buy one!
