Electric arc welder system with waveform profile control for cored electrodes |
摘要 |
<p>An electric arc welder for creating a welding process in the form of a succession of AC waveforms between a particular type of cored electrode, with a sheath and core, and a workpiece by a power source comprising an high frequency switching device for creating the individual waveforms in said succession of waveforms, each waveform having a profile is formed by the magnitude of each of a large number of short current pulses generated at a frequency of at least 18 kHz where said profile is determined by the input signal to a wave shaper controlling said short current pulses; a circuit to create a profile signal indicative of said particular type of electrode; and a select circuit to select said input signal based upon said profile signal whereby said wave shaper causes said power source to crate a specific waveform profile for said particular type of cored electrode. <IMAGE></p> |
