20130112676 | HYBRID PULSED-SHORT CIRCUIT WELDING REGIME - Welding power is generated by first generating two different current waveforms, and comparing the waveform values for control intervals to select which waveform provides the greater current. The waveforms are for different transfer modes, such as one for a pulsed arc portion, and another for a short-circuit transfer mode or for short-circuit clearing. The waveforms may be programmed by settings in a state machine. A balance or relative prioritization in the comparison may be influenced by user inputs. The resulting hybrid process has aspects of both spray transfer and short-circuit transfer modes. | 05-09-2013 |
20130112677 | WIRE FEEDING SYSTEMS AND DEVICES - Provided herein are systems including a wire spool having a core with a core diameter and wire wound around the core and having a wire diameter. An outer diameter of the wire spool is defined by a sum of the core diameter and the wire diameter. The systems may also include a sensing system having a sensor component disposed on the wire spool and/or a wire spool hub. The sensing system is adapted to acquire data corresponding to a parameter indicative of the outer diameter of the wire spool. | 05-09-2013 |
20130112784 | Powder Gun Deflector - A system for dispensing pulverulent coating material comprises a source of pulverulent coating material, a source of compressed gas, a device for movably supporting a nozzle, the nozzle coupled to the source of pulverulent material and providing an opening through which the pulverulent material is dispensed, a deflector supported by the device and spaced from the opening to aid in shaping a cloud of dispensed coating material, and a source of high-magnitude electrostatic potential coupled to impart electrostatic potential to the dispensed pulverulent material. The deflector includes at least one first passageway extending with a radial component of the deflector and communicating with the source of compressed gas to direct gas with a radial component into the cloud of dispensed coating material. | 05-09-2013 |
20130118368 | DISPOSABLE CUP INSERT FOR PAD PRINTING AND DECORATING - A liquid supply assembly for use with a printing system of a type in which a liquid is deposited from the liquid supply assembly in a receiving region on a plate and any excess of the liquid in the receiving region is scraped from the plate by the liquid supply assembly. To this end, the liquid supply assembly employs a reusable cup, a disposable cup insert and a scraping element. As assembled, the reusable cup includes a reusable liquid reservoir, the disposable cup insert includes a temporary liquid reservoir holding the liquid within the reusable liquid reservoir, and the scraping element includes a conduit facilitating a flow of the liquid held by the temporary liquid reservoir through the conduit to the plate. | 05-16-2013 |
20130126499 | SYSTEMS AND METHODS FOR DIAGNOSING SECONDARY WELD ERRORS - A controller for a welding system adapted to determine a value of a weld secondary parameter across a weld secondary component based on a sensed parameter is provided. The controller may also be adapted to compare the determined value to a reference value range and to alert a user to a presence and location of a weld secondary error when the determined value is outside the referenced value range. | 05-23-2013 |

The body has a work surface with a peak and sloped slides adjacent each side of the peak at approximately 45 degrees. The sloped surfaces allows the blind guide work contact tip to better access corners and angled spaces than previous work contact tips. The work contact tip also has a flat portion at the peak of the work surface so as to not inhibit face nailing. | 07-11-2013 |
