Patent number: 11203078Abstract: A method and apparatus for providing a welding type power is disclosed. It includes an outer housing having a wind tunnel within the outer housing. Air flows through the wind tunnel in an air flow direction. The width of the tunnel is less at one location than at another location. Electrical components receive power and provide a welding type output. A first group of those components require air flow for cooling, and are disposed at least partially in the wind tunnel.

Patent number: 6933467Abstract: A method and apparatus for welding is disclosed. The method includes sensing the status of a trigger between an on position and an off position. A system latch is set or released based on the trigger status and the latch status. The system latches on when the trigger is held for a predetermined time (and the latch was previously off). The latch is released when the trigger is pulled and released when the latch was previously on. When the latch is off, pulling the trigger turns the system on, and releasing the trigger before the predetermined time turns the system off. The latch may also be released when welding current drops below a threshold. The time might not start until after welding current is flowing. A welding wire feed speed control potentiometer on a torch is also disclosed. The range of the torch potentiometer is from a minimum to a value dependent on the control panel welding wire feed speed. A run-in wire feed speed control is also disclosed.Type: GrantFiled: February 26, 2004Date of Patent: August 23, 2005Assignee: Illinois Tool Works Inc.Inventors: L. Thomas Hayes, Kenneth C.

Patent number: 6689987Abstract: 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.Type: GrantFiled: February 16, 2001Date of Patent: February 10, 2004Assignee: Illinois Tool Works Inc.Inventors: Kenneth C.

Patent number: 6444950Abstract: 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.Type: GrantFiled: February 16, 2001Date of Patent: September 3, 2002Assignee: Illinois Tool Works, Inc.Inventors: Kenneth C.
