RC-8 For General Purpose and Vertical Down Root Runs Class of: AWS A5.1 E6013 JIS Z 3211 D4313 DESCRIPTION RC-8 is a versatile medium cellulose plus content mild steel electrode for all positional welding but particularly advantageous for vertical down welding. This electrode welds with a smooth stable arc on DC but it’ s also well suited for AC welding. Spatter is minimal. Weld seams are smooth, bright and evenly rippled. Initial arc strike and re-strike are instant. APPLICATIONS All positional welding but used to particular advantage for vertical down fillet welding of the following and related steel specifications: Mild and medium carbon-manganese steels up to 15 mm thick with a UTS of 500 N/ mm² max. Typical grades : BS 1449 plate and sheet, BS 4360 grades 43A and 43C, Lloyds A & D ship steel BS 4360 grade 50B Lloyds grades AH and DH, BS 3059 and BS 3601 grade 320-410 API 5L A-B and X42. INSTRUCTIONS 1.Choose the welding current within the suitable welding current range. 2.Electrodes that have become damp should be re-dried at 110º C for 1 hour.
