Wayne market area and to imprint the mark upon radio listeners. WMEE introduced substantial evidence into the record of publicity given to WMEE by area newspapers in which WMEE is always identified by its call letters. WMEE does have another promotional slogan. However, the slogan is used in conjunction with its call letters WMEE. WMEE is the number one radio station in the Fort Wayne market area as rated by Arbitron, the national rating service for radio stations, for the period of Spring 1984. The strength of WMEE's mark is demonstrated by the fact that when the defendant considered changing its call letters in June of 1984 to WMCZ, the only radio station contacted about that change was WMEE. Defendant, thus, was aware of the dominant soft rockfor shallow welds since less heat is generated in the base material. Instead of flowing from the electrode to the base material, as in DCEN, electrons go the other direction, causing the electrode to reach very high temperatures. To help it maintain its shape and prevent softening, a larger electrode is often used. As the electrons flow toward the electrode, ionized shielding gas flows back toward the base material, cleaning the weld by removing oxides and other impurities and thereby improving its quality and appearance.

Alternating current, commonly used when welding aluminum and magnesium manually or semi-automatically, combines the two direct currents by making the electrode and base material alternate between positive and negative charge. This causes the electron flow to switch directions constantly, preventing the tungsten electrode from
