ABSTRACT:
An improved underwater arc-welding apparatus that includes a handheld torch assembly connected to an housing that delivers electrical power, a pressurized shielding gas, and a consumable wire electrode to the site of the weldment. The housing is configured such that the diver/operator, himself, can control such welding parameters as the voltage level of the electrical power, the duration of the flow of the shielding gas, and the delivery rate of the electrode. In addition, the housing is configured to allow the entry of water into the space between its components, and these components, including an electric motor that advances the consumable wire electrode, are sealed individually from the water. Electrical connections between the components are effected using underwater cables and connectors. This configuration enables the apparatus to have a relatively non-bulky construction, which facilitates its convenient transport underwater by the diver/operator and further facilitates the servicing and/or replacement of components while the housing is submerged.
