  • Patent number: 6710300
    Abstract: A current path for a mig welding gun assures a reliable and stable interface between a welding gun and a weld wire. In one embodiment, the current path is through a conductive insert that fits in the welding gun diffuser. Fingers of the insert resiliently contact the weld wire and thereby provide stable paths for welding power from the gun to the weld wire. In another embodiment, a contact tip assembly comprises a contact tip having resilient fingers in electrical contact with a body. An inner frusto-conical surface of a sleeve is urged against concentric frusto-conical outer surfaces of the fingers to bias the fingers radially inwardly against the weld wire. An insulative liner in the contact tip guides the weld wire between the fingers. A shield surrounds the contact tip and the sleeve. In a further embodiment, a single finger is pivotally connected to the contact tip. A spring biases a finger end against the weld wire.

  • Patent number: 6689987
    Abstract: A MIG welding gun contact tip has a cylindrical section with a predetermined outer diameter adjacent one end, and frusto-conical surface adjacent the other end. Threads are rolled from the cylindrical section outer diameter between the cylindrical section and the frusto-conical surface. The threads major diameter is larger than the cylindrical section outer diameter, and the threads minor diameter is less than the cylindrical section outer diameter. In a preferred embodiment, the cylindrical section outer diameter is approximately 0.350 inches, the threads have a major diameter of approximately 0.375 inches, and the threads are stub acme threads with a pitch of 14 threads per inch. The contact tip is assembled to a diffuser having mating threads and a frusto-conical surface that engages the contact tip frusto-conical surface when the contact tip has been turned a single turn into the diffuser.

  • Patent number: 6679415
    Abstract: A fastener collation strip has pairs of vertically aligned rail-engaging members or projections which have convergent sides disposed within at least two mutually orthogonal planes such that lower and upper tip regions of the rail-engaging members or projections define point-type contacts whereby the fastener collation strips are movably supported upon the rail members of the magazine section of the fastener-driving tool. As a result of the point-type contacts, frictional forces generated between the collation strips of fasteners and the rail members of the magazine section of the fastener-driving tool are effectively reduced as much as possible whereby the conveyance or transportation of the collation strips of fasteners through the magazine section of the fastener-driving tool is effectively facilitated so as to render the conveyance or transportation of the collation strips of fasteners through the magazine section of the fastener-driving tool as smooth as possible.

  • Patent number: 6581641
    Abstract: A valve assembly mounted in a resealable/reclosable storage bag. The valve assembly includes a base and a valve element. The valve element includes a stem with a convex cap attached at one end and a valve gate attached at the opposite end. The stem extends into a hole in the base. The resilient quality of the cap, acting against the top of the base, holds the gate against the bottom of the base, thereby forming a seal between the gate and the base that is strong enough to preserve the vacuum inside the bag. A cavity extends into the stem from the cap end. A hole in the stem runs from the cavity to outside the stem. When the stem is pressed down, a vacuum source may draw air between the gate and the base, through the hole in the stem, into the cavity, and subsequently outside the bag.

  • Patent number: 6575191
    Abstract: A one-way valve allows air to be drawn from a collapsible, flexible, air-tight bag using a vacuum source. When the vacuum source is removed, the one-way valve prevents air from re-entering the bag. A filter is placed on the valve body to prevent small particles from the bag from clogging the valve or the vacuum source.

  • Patent number: 6536644
    Abstract: A wire feeder comprises a feedroll with through slots that open into a bore and that extend between the feedroll ends. The feedroll has blind slots in the ends that also open into the bore. A shaft on the wire feeder has a radial pin. The feedroll is assembled on the shaft by angularly aligning the through slots with the pin and pushing the feedroll onto the shaft against a spring until the feedroll is past the pin. The feedroll is rotated on the shaft until the blind slots align with the pin. Then the feedroll is released to enable the blind slots to engage the pin under the force of the spring. The feedroll may be assembled to the shaft either in a manner that takes up any end play of the shaft, or that enables the feedroll and shaft to float through the end play.

  • Patent number: 6525297
    Abstract: A MIG welding gun has a diffuser with an external thread and a frusto-conical back ramp. A nozzle assembly includes an insert with a back ramp and a thread that mates with the diffuser thread. The threads of the diffuser and insert have respective ramps that mate. A single turn of the nozzle assembly on the diffuser causes simultaneous engagement of the insert and diffuser back ramps and of the insert and diffuser thread ramps. Such engagement centers the nozzle to be concentric with the diffuser and also produces a wedging action that retains the nozzle assembly on the diffuser until a relatively substantial reverse torque is applied to the nozzle assembly. The nozzle front end has a narrow annulus, which reduces the amount of radiant heat from the welding arc that reaches the nozzle.

  • Patent number: 6489591
    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.
