摘要： Methods and systems for clearing short circuits during a MIG welding process are disclosed. A method may include detecting a short circuit and increasing output current of a power source at a first ramp rate to clear the short circuit. The method further includes increasing output current at a second ramp rate after the output current reaches a threshold. Power sources and systems implementing the method are also provided.

摘要： Methods and apparatus for initiating an arc (e.g., a welding arc) by placing liquid droplets containing ions in the gap between an electrode and a workpiece. This is done while a potential difference is applied between the electrode and the workpiece. The presence of the ions renders the gap 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 potential difference, the arc will be initiated.

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： An apparatus and method of manufacturing a plasma torch consumable is disclosed. The invention includes at least two of a tip, a shielding cup, an electrode, and a swirl ring being integral to form a unitary one-piece assembly prior to being attached to the torch. Such a construction minimizes the number of parts that must be handled and orientated when connecting the consumable assembly to a plasma torch.

摘要翻译： 用于控制焊接型电源的方法和装置包括提供具有电弧电流部分和短路电流部分的电流波形。 通过缩回焊丝进入电弧状态，并且通过前进导线进入短路状态。 在产生电弧之前，电流进入电弧电流部分，并且在创建短路之前，电流通过将波形与电线回缩协调来进入短路电流部分。 这可以在直径为2.4mm以上的焊丝上进行焊接，并施加小于100安培或小于35安培的焊接电流。 在电弧状态期间的一个电流波形包括至少三个段，并且最后一个段在进入短路状态之前进入，并且与在短路状态开始时的电流幅度相同。 穿透和/或珠形成可以通过控制线进入焊池来控制。 天平可以是用户设置的。

摘要： The present invention is directed to a MIG welding machine having a 115 volt inverter. Incorporation of the 115 volt inverter into the MIG welding power source reduces the weight of the power source thereby increasing its portability. The power source may include a power factor correction circuit to provide a near-unity power factor such that output power of the inverter is more efficiently provided. Additionally, the 115 volt inverter is constructed such that for short periods of time, the inverter may output power at a level that exceeds its power rating.
