Barracuda Gold

The Barracuda 'Gold' is a special rutile flux coated welding electrode with added nickel. It was developed to provide a high quality, cost effective electrode, that is easy to use for all structural steels. It has a special formulated clear polymer based waterproof coating, to ensure the maximum resistance to water and moisture penetration. The electrode allows for higher levels of misuse in its handling and care, and provides electrical insulation for improved diver safety. The electrodes are available in 3.2 and 4mm (1/8" and 5/32") and are boxed in plastic telescopic containers. See Technical Data.

The electrode has a particularly smooth, soft arc characteristic that welders find very pleasing and easy to use. The electrode produces a superb weld finish and the slag is easily removed. It offers easy striking and re-striking and may be used in all positions. The electrode provides for excellent mechanical properties, with welding procedures having been approved by Lloyds and ABS. The nearest specification equivalent, in accordance with BSEN ISO 2560: 2005 may be regarded as; E4621NiRR51 and/or American Welding Society; AWS A5.1:2004 E7014.
