ACW, LLC uses a Miller wire feed welder for most all of our welding. All welding is done with shielding gas. The Miller is a versatile machine which with just a switch of wire and shielding gas can do stainless steel, and with another shielding gas switch can do aluminum. ACW, LLC is also set up to cut, weld, braze, or solder with an Oxy/Acetylene setup too if that is what is required.
