摘要： Embodiments of a tungsten inert gas (TIG) welding torch with an improved air cooled handle are provided. The welding torch may include a body, a cable assembly, and a torch head, with a handle placed over the body and the cable assembly. The handle may feature a curved end designed to fit near the torch head without contacting the torch head, providing a closer gripping point to allow greater control of the torch. In addition, the handle may be spaced from the body and the cable assembly to form an air space within the handle through which air may flow to cool the handle.
摘要翻译：提供了具有改进的空气冷却手柄的钨惰性气体（TIG）焊枪的实施例。焊炬可以包括主体，电缆组件和炬头，手柄放置在主体和电缆组件上。手柄可以具有弯曲的端部，其设计成适合靠近炬头，而不接触炬头，提供更紧密的夹持点以允许更好地控制割炬。此外，手柄可以与主体和电缆组件间隔开，以在手柄内形成空气空间，空气可以通过该空气空间来冷却手柄。

摘要： The invention provides a high flow power cable for a welding system designed for effective cooling of the power cable while maintaining maneuverability of the cable. Provided is a power cable having two segments, the first segment being larger in diameter than the second segment. The first segment is generally coupled to the power source and the second segment is coupled to the welding torch. The first segment includes a thicker wire, which has less resistance and dissipates less heat while the second segment includes a thinner wire, allowing for easier handling. Additionally, cooling fluid is conducted through the first segment and the second segment, further cooling the cable.
摘要翻译：本发明提供了一种用于焊接系统的高流量电力电缆，其设计用于有效地冷却电力电缆，同时保持电缆的机动性。提供了一种具有两个段的电力电缆，第一段的直径大于第二段。第一段通常耦合到电源，第二段耦合到焊炬。第一段包括较粗的线，其具有较小的电阻并且消耗较少的热量，而第二段包括更细的线，允许更容易的处理。此外，冷却流体通过第一段和第二段传导，进一步冷却电缆。

摘要： Systems and methods for improved liquid cooling of a tungsten inert gas (TIG) welding torch are provided. The improved welding torch may feature conduits for conveying coolant from a cooling system to a collar, which holds a tungsten electrode of the welding torch, and back. A coolant return conduit may be disposed in a coolant supply conduit to improve thermal insulation of an outer surface of the welding torch. Some embodiments may feature a helical channel formed in the collar for conveying coolant around the electrode multiple times before returning the coolant through the return conduit.

摘要： A connector for connecting together a welding torch power cable including a threaded connector, a coolant line and a shielding gas line to a welding power and/or coolant source including a connector receptacle includes an electrically conductive tubular body having a front end and a back end. The tubular body front end is adapted to receive and connect to the power cable threaded connector. The tubular body back end is adapted to connect to the connector receptacle. The tubular body also includes a passageway therein to communicate shielding gas or coolant between the source and the torch. A hose connector is attached at an end of the passageway. A casing including a longitudinally extending tubular side wall terminates in front and back ends. A twist cap is releasably connectable to the back end of the casing. A cable cover adapter is releasably connectable to the front end of the casing.
