The 1000$ machine, or less works very well and can be all the machine a guy needs for good long time. A hobby guy cant wear out a new Hobart if he tried. It is kind of a cheaper Miller but,,, it is cheaper and works just as well, shares so many same parts, and the main thing makes it cheaper is the simplicity of tap voltage, the blue one has all the latest greatest features, surprised it doesn't have a radio a fridge a 3 ft blonde with a flat head, got so much stuff on it that its not really a help.
It distracts from learning the settings. Its trying to compensate for error and a guy is filling big ole open fitups etc. If a guy has variable he needs a meter. My go to has a 5 speed that I have been using same thing for decades and thousands of beads. 3 settings, thin, medium and thick.
Much or mostly on thick due to it being 030 and a small machine, you can weld thin a lot faster. Start getting around 12 gage and thicker and it can b wide open which provides the real melting power, super for stock car chassis etc. The operator can learn to run it just short of burning thru and even root fill. I rarely bevel a 1/4 plate, just leave some gap so I can melt a hole in it and add filler.
