1. Here are two of Miller’s latest MIG welders, aimed at the DIY homebuilder, the Millermatic 180 and 211. Both welders are equipped with Miller’s exclusive Auto-Set function that automatically determines the wire speed required by setting the material thickness to be welded and the welding wire diameter. This function takes most of the guesswork out of the equation when it comes to setting up a welder by the inexperienced. The 211 has another Miller exclusive, the MVP or multi-voltage plug function, which allows the welder to be powered by either 120- or 230-volt power receptacles by simply swapping the provided plug ends. For our exercise, we’ll be using the 180 exclusively, given its broad range, from 24-gauge sheetmetal to 5⁄16-inch plate.
