摘要： A welding system includes an engine-driven welder generator that produces welding power. A welding torch receives the welding power and applies it to a stick electrode to initiate and maintain a welding arc. A parameter of the welding power, such as voltage, is monitored, such as to determine whether spikes occur during a short time after arc initiation. Based upon the monitored parameter, the engine speed is controlled. The engine speed may be increased or maintained at an elevated level if the monitored parameter indicates that particular types of electrode are being used, such as XX10 or cellulose electrodes.

The front end portion of the wire is preheated to 300° C. or higher, preferably, 450° C. or higher. The front end portion of the wire is preheated by generating arc for preheating. The preheating arc is generated in a spot-like shape at a position near a terminal end portion of a predetermined welding line by constituting a current lower than a welding current.

摘要： A system and method for forming an arc between an electrode and a workpiece is disclosed. The present invention includes a method of initiating an arc that includes comparing voltage across output terminals of a stick welder to a voltage threshold, and if the voltage across the output terminals is less than the voltage threshold, increasing the voltage across the output terminals to an arc formation OCV. The output voltage of the stick welder will be driven to a lower OCV if an arc is not formed between an electrode and a workpiece within a given period of time.

摘要： A microprocessor-controlled are welding power supply is disclosed. A silicon controlled rectifier ("SCR") bank is used to generate a direct current arc welding current under program control. Positive synchronization is provided by the microprocessor using a phase locked loop and a polarity detector, so that the gating signals applied to the SCRs are correctly timed. Optimum tradeoffs between hardware and software are accomplished by using look up tables to store correction factors that can be quickly accessed during execution, and by using timers as smart interface chips to fire the SCRs at the same angle during each cycle until changed or updated by the microprocessor. The arc welding power supply is capable of operating in a constant current or constant voltage mode without rewiring the circuit.
