The Arcair® Arcwater®Torch is designed to gouge or cut steel, stainless steel and other metals underwater safely, easily and efficiently. Arcwater can also be converted to an underwater welding torch by simply changing collets. The unique Arcwater torch is oxygen free, eliminating the risk of hydrogen gas pocket explosions. Tests conducted at Arcair and by diving contractors prove the following: 1) Arcwater Torch is easy to handle by right or left-handled users. 2) Arcwater can be used on out-of-position applications as well as on easy to reach jobs. 3) Arcwater’s valve/lever assembly allows the operator to easily control water flow. 4) The replaceable collet means longer torch service life than ever before.
Arcwater uses current from a DC power source, reverse polarity (DCEP) and a special Arcair Arcwater electrode. Fresh or sea water must be delivered to the torch at 90 psi (6.32 kg/cm2 or 620 kPa) over the pressure at the depth of use. A minimum water flow rate of 3.5 gallons (13.25 liters) per minute is required. With the Arcwater process, 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.
