Arcair Sea Jet 9.5mm x 457mm Underwater Exothermic Cutting Electrodes Box of 50
An exothermic cutting electrode that is made up of a 3-piece construction consisting of an outer steel tube, with an steel wound spring and a hollow inner tube. Does not need constant welding current to sustain the cutting action.
Patented underwater exothermic Sea Jet cutting electrodes will burn ferrous and melt non-ferrous materials such as concrete, rock, barnacles and other sea growth. The Sea-Jet electrode can be used like other oxygen-arc cutting electrodes. A DC constant current welding power supply on straight polarity (electrode negative), ground the workpiece and by touching the workpiece an electric arc ignites the electrode. Once ignited the electrode will continue to burn by the means of an exothermic reaction between the steel components of the electrode and the oxygen flowing through the electrode. Remember, Sea-Jet Electrodes will burn as long as the oxygen is flowing through the electrode. For igniting the electrode only, a 12 VDC battery may be used. This presents an added safety margin against the possibility of electrical shock.
