Lincoln Electric has obsoleted shunt coils for code numbers 7040 through 8790, commonly known as thick shunt coils, . The machines have the Octagon (8-sided) stator housing. Original Lincoln coils were very cheaply made, with aluminum wire painted to look like copper, wound on a sheet-metal bracket, and covered with paper insulation. 

Weldmart's version of these coils is wound on a rigid, industrial plastic one-piece "bobbin"; the mold to make this bobbin cost $30,000 30 years ago. It will not absorb moisture. 

These coils are sold with an "across the counter" warranty for 10 years.
