hydraulic power tools Equipment Sea Torch Combination Torch The Sea Torch is an improved underwater cutting and welding torch with a one piece body construction. It is fully insulated electrically for safety in normal operation. The one piece body prohibits oxygen leakage in the torch body, which can occur with torches having connections between the head and the handle The torch has a tapered collet which brings the bare surface of an electrode into contact for the entire length of the collet. This solid grip and increased contact area decreases the risk of arcing between the collet and the electrode and damaging the torch head. By loosening two set screws, the oxygen valve and lever can be rotated to different positions to provide easier oxygen flow control for the diver. The torch has a spark arrestor located behind the collet chuck for safe operation. A ball check valve in the torch handle gives additional protection. The torch comes with a 10ft. (3.05m) cable which can be disconnected from the torch. Arcwater II Torch The Arcwater Torch is designed to gouge or cut steel, stainless steel and other metals underwater safely, easily and efficiently. The torch also can be converted to an underwater welding torch by simply changing collets. Arcwater Torch is easy to handle by right or left-handed users. The unique Arcwater torch is oxygen free, eliminating the risk of hydrogen gas pocket explosions. The torch uses current from a DC power source, reverse polarity (DCEP) and a special Arcwater electrode. Fresh or sea water must be delivered to the torch at 90 psi (6.32 kg/cm2 or 620 kpa) over the bottom. A minimum water flow rate of 3.5 gallons (13.25 liters) per minute is required. The metal is made molten by the electrode coming in contact with the work piece, forming an arc. The molten metal is then removed by the high pressure water stream, leaving a clean slag-free gouge ready for welding. Three special collets are available to adapt the Arcwater II Torch for underwater welding with 1/8 (3.2 mm), 5/32 (4.0 mm) or 3/16 (4.8 mm) Sea-Weld electrodes. ndt equipment / video and lighting systems To use the above torches for underwater welding, there are collet chucks available for use with the Sea-Weld underwater wet welding electrodes.

Electrodes Sea Dragon Cutting Electrodes 42-075-005 The New Sea Dragon Underwater exothermic cutting rods will burn most materials and can be used like any other oxygen-arc cutting electrodes. Once ignited the electrode will burn by means of an exothermic reaction. When cutting without power a 12 VDC battery may be used for ignition only which is an added safety margin against the possibility of electrical shock. Sea Jet Cutting Electrodes 42-066-006 Will burn ferrous and melt nonferrous materials such as concrete, rock barnacles, and other sea growth.
