摘要: A method and apparatus for welding include initiating a pulse welding process includes initiating a welding arc by providing CC type welding power, maintaining the arc by providing CV type power. Then, pulse type welding power is provided. The method and system can be used to start short circuit, or other welding processes by providing short circuit power, or welding power of a given mode, instead of providing pulse power. Also, in one alternative, a method and system of initiating a pulse, short circuit, or given welding process includes initiating a welding arc by providing CC type welding power at least until a pseudo-equilibrium for the arc is established. Then, providing welding power in a pulse, short circuit, or the given mode.

摘要: A short circuit arc welding system is disclosed. The control scheme uses a current command signal comprised of a long-term current command that sets the long-term current command level and a real-time or short-by-short current command to drive the output current. Feedback is used to determine if the desired arc length is present and to adjust the long-term command. The short-by-short current command is derived from real-time arc current feedback and is used to control the burn-off rate by adjustment of the current command. The short being about to clear is detected in real time. When the process is ending a very low current level is provided to avoid forming a ball. If a short is created, after the low current level, a burst of energy is provided to clear of burn off the short. After the short is cleared, very low current is again provided to avoid forming a large ball, until the wire stops and the process ends.

摘要: A welding cable designed to work with a welding system that does not have a pull-type torch is disclosed. The cable includes an electrode lead and an arc voltage sense lead. An insulating jacket is disposed about the electrode lead. The arc voltage sense lead is physically attached to the insulating jacket, along at least a substantial portion of the insulating jacket. The torch lead is preferably fixedly attached to the torch. The sense lead is connected to a controller. The sense lead may be disposed inside or attached outside the insulating jacket. The arc voltage sense lead may be attached to the electrode lead, rather than the torch itself.
