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.

Abstract: A welding apparatus having a system to facilitate its assembly. The apparatus is assembled by affixing a pair of molded end panels to a molded base and each of the end panels has a specially constructed receptacle area that is adapted to receive an end of the base. Each end of the base has a pair of snaps that extend outwardly and which engage with a correspondingly located pair of ramps formed in the receptacle area of each of the end panels. Thus the assembly is easily carried out by simply inserting the base ends into the receptacle areas where the snaps ride up the ramps and engage the vertical walls on the inner side of those ramps to securely affix the end panels to the base. Preferably the snaps are U-shaped in configuration with the distal end of the snaps being the closed ends of the U-shaped snaps.

Abstract: A snap-in heat sink assembly that has an injection molded one piece frame having a plurality of spring members extending outwardly with protrusions at the free ends thereof. The assembly has a spring located against the frame and an electronic component is located atop of the spring. A heat sink has lateral surfaces with elongated grooves formed along those lateral surfaces. The sink is affixed to the frame by a simple step of inserting the heat sink into the space between the spring members such that the protrusions of the spring members snap into the grooves when the heat sink is in the desired location. By sandwiching the spring between the frame and the electronic component, the spring creates a bias to force the electronic component against the heat sink to assure good conductivity of heat from the electronic component through the heat sink.

Abstract: A power cord assembly for a welding-type power supply includes a power cord and a plurality of adaptors. The power cord is adapted for attachment to the welding-type power supply and is capable of providing any of a plurality of input voltage signals to the welding-type power supply via the plurality of adaptors.

Abstract: A welding machine power supply has two circuits for cooling air. A primary circuit comprises a magnetics chamber and a second chamber. A fan between the magnetics and second chambers draws atmospheric air through one end panel into the magnetics chamber and blows it through the second chamber. The second chamber is comprised of a pair of heat sinks. Major heat generating components are mounted to the heat sinks outside the second chamber. The fan is sandwiched between the magnetics chamber and the heat sinks such that all the air blown by the fan flows through the heat sinks and out a second end panel. A wind tunnel is also part of the second chamber. A counterflow circuit extends from the second end panel to the magnetics chamber. The negative pressure in the magnetics chamber draws atmospheric air through the second end panel to the magnetics chamber, thereby cooling minor heat generating components outside of the primary circuit and not associated with the heat sinks.

Abstract: A spark gap assembly includes two conductive spark gap points forming a spark gap. Two substantially identical, non-conductive, molded plastic pieces are clamped together to make a housing with at least one cylindrical receptacle for the spark gap points. Two conductive leads electrically contact the spark gap points and abut and electrically contact circuit board leads when the assembly is mounted on a circuit board. The housing pieces include at least one fastening hole and a fastener extends through the fastening holes when the pieces are assembled, thus clamping the together. The two pieces have at projections on the bottom that are received in holes on the board, thereby positioning the pieces.
