Millermatic Electric Welders - Overview

Miller Electric is one of the largest companies that manufacture cutting equipments and arc welding machines. The company is based in Appleton, Wisconsin and it is also manufactures quality welding accessories such as helmets, welding carts, machine covers and other items. This company was started in 1929 by Niels Miller. The first machine from this company was a small arc welder which was only compatible with electrical supplies in Winsconsin. This machine was more lightweight than the DC rotary machines which were already in use. The first machine was made from recycled scrap steel. In 1935, it incorporated the Miller Electric Mfg. Co.

Later in 1971, this company developed the Millermatic which combined the power source and wire feed of the previous models. After the death of the company’s heir which happened in 1993, this company was acquired by Illinois Tool Works[ ITW]. The company is a multinational company that is based in Chicago.

Today Miller MIG welders are among the most preferred by professionals. As compared to other models, these welders provide incredible results when welding. They also work perfectly with different metals. However, some Millermatic welders such as the Millermatic 252 are more powerful than others.
