Notification The purpose of changing the designation system We, Welding Company of Kobe Steel, Ltd., thank you very much for your continuous patronage of our products and services. We have changed the designation system of welding consumable as described in the following from April 2008. However, the technical design of the products is not changed. New group brand names and the corresponding products All KOBELCO welding consumables are designated with “Trade Designation” and are grouped into the following three new groups on the basis of the characteristics of individual products as detailed below. (1) (Famili-Arc) A coined word produced by combining “Familiar” and “Arc.” Welding consumables grouped into this group are used for general welded structures made of mild steels and high tensile strength steels that have the tensile strength of less than 590 MPa. (2) In recent years, we have found some other companies’ products that have the same brand names as ours and false certificates that misrepresent our company’s certificates in Japan and the Asian countries. In order to cope with this problem, we have taken legal actions against the impostors that could be verified and have required them to change their product names. However, it is difficult in the traditional product designation system to protect all of our products from imitation. Hence, we have established the new designation system of welding consumable to ensure the trademark right in main countries and to make our products identifiable more clearly, in which the particular group brand name, “Trademark,” is put on the head of an individual “Trade Designation.” The new designation system is not only to prevent counterfeit products in Japan and overseas countries, but also to prevent our customers and users from suffering such a trouble in terms our products. This modification may cause customers and users to modify their relevant documents. We sincerely hope for your understanding of the abovementioned situation and for your cooperation with us. (Trust-Arc) A coined word produced by combining “Trust” and “Arc.” Welding consumables grouped into this group are used for such steels that require highly credible qualities as high tensile strength steels with the tensile strength of 570 MPa and higher, low temperature steels, and heat-resistant low-alloy steels. (3) (Premi-Arc) A coined word produced by combining “Premium” and “Arc.” Welding consumables grouped into this group are used for high-alloy steels, stainless steels, and nonferrous metals. The new group brand name (referred to as “Trademark” hereinafter) is put on the head of an individual trade designation. The trade designatio
