摘要： Methods and apparatus for initiating a welding arc by directing a plasma jet into the space between the tip of the welding electrode and the workpiece. This is done while an electrical potential is applied between the electrode and the workpiece. The ionized plasma gas renders the space between the electrode and the workpiece more conductive, thereby reducing the voltage threshold needed to initiate an arc between the electrode and the workpiece. When the voltage threshold reaches the level of the applied electrical potential, the arc will be initiated.

摘要： Methods, controllers, and power sources for controlling weld states of a MIG welding machine having a 115 volt inverter are provided. The regulation of a power source may include determining a command current signal based on a maximum allowable voltage error determined from the output condition at the weld. The signal may be provided to a controller that regulates the output of the 115 volt inverter. A MIG welding power source may include the 115 volt inverter and a processor that determines a maximum allowable voltage offset from a voltage feedback signal and a voltage level. The processor may provide a signal based on a determined instantaneous command current to regulate the 115 volt inverter.

摘要： A method and apparatus for controlling a welding-type power supply includes providing a current wave form having an arc current portion and a short circuit current portion. An arc state is entered by retracting a welding wire, and a short circuit state is entered by advancing the wire. The current enters the arc current portion prior to the creation of the arc and the current enters the short circuit current portion prior to the creation of the short, by coordinating the wave form with the wire retraction. This may be preformed on a wire having a diameter of 2.4 mm or more to a weld and applying a welding current of less than 100 amps, or of less than 35 amps. One current waveform during the arc state includes at least three segments, and the last segment is entered into prior to the short circuit state being entered, and is the same current magnitude as the current magnitude at the start of the short circuit state. Penetration and/or bead formation may be controlled by controlling the advancement of the wire into the weld pool. The balance may be user set.

摘要： The present invention is directed to a system and method for improved operational feedback from a plasma torch to a plasma-cutting power source. A plasma cutter includes a plasma cutting power source, a plasma torch in communication with the plasma cutting power source, and a serialization circuit disposed within the plasma torch to control transmission of multiple feedback signals from the plasma torch to the plasma cutting power source. The serialization circuit receives the multiple feedback signals and places the feedback in a queue, such that the multiple feedback signals are sent from the queue to a processing unit in the power source via a single communications link.

摘要： A gas cylinder lifting system is useful for loading and unloading heavy tanks of gases onto and off of a welding power supply running gear. The gas cylinder lifting system comprises one or more sliders that are constrained for vertical reciprocation on a frame mounted to the running gear. The slider includes a pan for supporting a gas cylinder. A crank lever is pivotally mounted to the frame by a pivot pin, and a linkage is pivotally connected between the crank lever and the slider. The linkage has a crook in it. Pivoting the crank lever to a first angular position lowers a slider and places the linkage crook remote from the pivot pin. Rotating the crank lever to a second angular position raises the slider and places the linkage crook adjacent the pivot pin. The crank lever and linkage cooperate to place the gas cylinder lifting system in an over-center self-locked condition when the crank lever is in its second angular position. A spring-loaded latch may be installed on the frame that positively maintains the crank lever at its second angular position but that is manually operable to enable the crank lever to rotate to its first angular position.
