Abstract
A welding implement and a method of extracting heat from a welding implement are disclosed. The welding implement includes one or more heat pipes which transfer thermal energy away from the torch head. A fluid, such as a shielding gas, may then convectively transfer the thermal energy away from the welding implement. The present invention thus provides a handheld welding implement that is compact, such that it can be used in confined spaces, and operated for longer periods of time, since the improved heat dissipation helps to maintain the welding implement at a temperature that an operator may hold.
