Nikko Steel 29/9 Electrodes (Dissimilar 312) 4.0mm

NSK-312 AWS A5.4 E312-17 Ø 4.0 x 300 mm RECOMMENDED CURRENTS : AC or DCEP 55 ~85 Amp Primarily designed for high carbon steels, cast or wrought, which are well known as difficult to weld or problem steels. The duplex micros weld metal will tolerate high dilution with such steels while still maintaining its strength ductility and thus resistance to cracking. It can also be used very successfully for joining carbon steels to stainless steels, the only exception to its extensive use on such applicant service temperatures above 300°C a drop in weld metal ductility occurs. For Joining Difficult To Weld High Carbon Steels and Dissimilar Metal Combination When No Exact Specification of The Base Metal Exists INSTRUCTIONS FOR WELDING: 1. Use the recommended current. 2. Keep the arc length as short as possible. 3. Do not use too much weaving. The bead width should be kept within 2.5 times of core wire diameter. 4. Electrodes that have become damp should be re-dried at 120°C for 30 minutes
