Superior Impact, Strength and Crack Resistance on Carbon Steels

EutecTrode 966 ®

WELDING • All position welding electrode • Easy-to-use, easy slag removal, versatile electrode • Non-sulfur bearing striker tip for instant starts • Good re-striking characteristics • Moisture guard coating with non-conductive flux coating • High strength combined with high elongation



EutecTrode 966 is a high quality electrode for low alloy, medium carbon and high tensile steels. Featuring rapid start, smooth arc control and easy slag removal. EutecTrode 966 was developed for joining and build-up on carbon steels, dirty steels, alloy steels, free machining steels and “problem“ steels without cracking or porosity. It provides excellent physical properties and is recommended where high strength, machinable, ductile, dense, crack-free and porosity-free welds are of paramount importance.

Preparation: The area to be welded should be free of surface contamination such as rust, scale, grease or fatigued metal. Preheat heavy section or hardenable grades of steel to 400° F (200°C). Use carbon equivalency on steel to establish recommended preheats.

TECHNICAL DATA: Tensile Strength: Yield Strength: Elongation (1=5d): Polarity:

86,000 psi (595 N/mm2) 75,000 psi (520 N/mm2) 36% AC/DC (+) All Position

Technique: For highest X-Ray quality welds, maintain a short arc gap and chip slag between passes. On vertical welds, start at the bottom and weave slightly, pausing at the edges. For root passes, at a minimum gap (3/32“ for 1/8“ electrodes) and run stringer beads. For fill and cover passes a weaving technique is best employed. Post-welding: Allow parts to slow cool in still air.

TYPICAL APPLICATIONS: General fabrication and maintenance of structural work, construction and earthmoving equipment, mining and quarry machinery repairs, truck and trailer frames, material handling equipment, farm implements and rail equipment.

WARNING Protect yourself and others. Read and understand this warning. THIS PRODUCT CONTAINS CHROMIUM AND/OR NICKEL which are listed by OSHA, NTP, or IARC as being a carcinogen or potential carcinogen. Use of this product may expose you or others to fumes and gases at levels exceeding those established by the American Conference of Governmental Industrial Hygienists (ACGIH) or the Occupational Safety and Health Administration (OSHA). READ AND COMPLY WITH THE OSHA PERMISSIBLE EXPOSURE LIMITS FOR HEXAVALENT CHROMIUM (CrVi), Fed. Reg. 71-10099. MANGANESE & RELATED COMPOUNDS SUCH AS MANGANESE DIOXIDE: Overexposure to manganese and its compounds may cause metal fume fever characterized by chills, fever, upset stomach, vomiting, irritation of the throat and aching of the body. Excessive overexposure may affect the central nervous system. Symptoms may include muscular weak ness and tremors. Behavioral changes and changes in handwriting may also appear. Workers exposed to manganese and its compounds should receive quarterly medical examinations of early detection of manganese poisoning. FUMES AND GASES can be dangerous to your health. Certain medical studies have suggested that NERVOUS SYSTEM and/or LUNG DAMAGE can result from exposure to welding fumes and gases through the use of some electrodes. ARC RAYS can injure eyes and burn skin. ELECTRIC SHOCK can kill. • Before use, read and understand the Material Safety Data Sheets (MSDS), the manufacturer’s instructions, and follow your employer’s safety practices • Keep your head out of the fumes. • Use enough ventilation, exhaust at the arc, or both, to keep fumes and gases from your breathing zone and the general area. Respirators may be needed and should be chosen by the employer based on workplace conditions and contaminant levels. For information regarding a respiratory protection program, see OSHA 1910.134 requirements. • Wear correct eye, ear, and body protection. • Do not touch live electrical parts. • In case of medical emergency, call for medical aid. •See American National Standard Z49.1, Safety in Welding and Cutting, published by the American Welding Society, 550 N.W. LeJeune Road, Miami, FL 33135; and OSHA Safety and Health Standards, 29CFR 1910, available from the U.S. Government Printing Office, Superintendent of Documents, P.O.
