WHY CHOOSE BARRACUDA ELECTRODES: Barracuda ‘Gold’ underwater welding electrodes have been designed and formulated to produce the highest quality weld metal possible for today’s demanding marine industry. These electrodes are the accomplishment of many years of knowledge and experience working in the welding industry. The electrodes are manufactured to the highest standards and are produced under strict quality control methods and procedures (ISO 9000) to ensure the highest quality at all times. For any wet welding electrode to produce high quality weld metal the waterproof coating must ensure moisture is prevented from penetrating the flux coating, while also being allowed to burn away without undue interference to the transfer of metal. In addition to this, we also offer the highest protection against the harsh environment in which these electrodes must perform. The Barracuda ‘Gold’ electrodes are guaranteed not to flake blister, or stick together prior to use, even under the harshest of environments. They offer the highest level of protection against physical damage of any other electrode on the market, whilst also providing electrical protection for the diver. Although no standard/specification exists for underwater welding electrodes, the nearest equivalent may be taken from BS EN ISO 499: 1995 for covered welding electrodes. The Nearest code being E46 2 1Ni RR 5 1 H15 or (AWS E7014). Barracuda electrodes exceed the specification criteria as stated under BS EN ISO 15618-1:2002 and AWS D3.6 Specification of underwater class ‘B’ welds. PERFORMANCE CHARACTERISTIC: These electrodes are designed to be used in all positions, using standard touch welding techniques, which are particularly well suited for inexperienced divers, while at the same time in the hands of more experienced divers allows for a friendly, controllable arc characteristic thereby, making welding as easy as possible. For detailed information on additional features of the electrode, see separate data sheet.

(What a difference a good electrode can make in the right hands).

TECHNICAL SUPPORT: Users of Barracuda ‘Gold’ electrodes can be assured of access to unlimited technical support from one of the worlds leading experts; including, Development of formal welding procedures Qualification of welder/divers Onsite assistance Project management / consultancy We can also offer publications to improve your understand on underwater welding; including,

‘The Professional Divers Manual on Wet Welding’ and ‘A Welder’s Mate’.
