Our Swordfish™ cutting electrodes require no special equipment whatsoever; a standard 350 - 400 amp DC welding power source, cables and our standard welding stinger are all that’s required. The electrode is available in a 5.0mm (3/16”) diameter. It can be used in all positions and it will cut a wide range of materials; including steel, stainless steel, cast-iron, bronze and copper alloys, and aluminium and its alloys, both above and below the waterline.
When conventional oxy-arc (exothermic) cutting is regarded as a safety hazard to the diver, or no oxygen is available, these electrodes offer a safe, convenient and cost effective alternative. These electrodes even offer a more convenient way of cutting for general engineering workshops, where onsite welding and cutting needs to be performed, as there’s no need to transport oxy-acetylene/propane cylinders in vehicles, which does require a licence in the UK.
The electrodes can be used for all general demolition works, such as piercing holes for bolts, removal of rivets and other connections and attachments common in constructional engineering.
All usual safe arc welding precautions must however be observed, with particular attention being drawn to the AODC code of practice “safe use of electricity underwater” for underwater use.

Swordfish Demonstration Video Clips:
Video 1 : Shows dry cutting demo using 5.0mm electrode to cut 20mm steel plate.See graphs above for comparison details between wet and dry cutting performance.
Video 2 : This video clip shows our new non-exothermic cutting electrode 'Swordfish' in action at a recent demonstration at Subsea 7 workshops, in Aberdeen. The electrode does not require any oxygen to cut and although this footage only shows the electrode being used in air, we hope that it provides sufficient evidence of its performance. The material being cut was 20mm carbon steel plate. The welding parameters were 340amps on DC -Ve. Following this demonstration a number of offshore clients have requested further trails be undertaken underwater at a range of depths down to -90M. We will of course keep you informed as to the progress.
