    When these parameters are identical, the pulsing fre- quency will be the same, helping to stabilize the arcs. Every welding gun requires a separate shielding gas regulator for proper flow rate and shielding gas cover- age. Do not attempt to supply shielding gas for two or more guns from only one regulator . If an anti-spatter system is in use, each ...

    VOL T AGE SENSING The best arc performance occurs when the Power W ave has accurate data about the arc conditions. Depending upon the process, inductance within the electrode and work lead cables can influence the volt- age apparent at the terminals of the welder . V oltage sense leads improve the accuracy of the arc conditions and can have a drama ...

    WELDING MODE DESCRIPTIONS CONST ANT VOL T AGE WELDING For each wire feed speed, a corresponding voltage is preprogrammed into the machine through special soft- ware at the factory . The preprogrammed voltage is the best average voltage for a given wire feed speed. With synergic programs, when the wire feed speed changes, the Power W ave will automa ...

  • Lincoln Electric SVM173-A - page 26

    PULSE WELDING Pulse welding procedures are set by controlling an overall “arc length” variable. When pulse welding, the arc voltage is highly dependent upon the waveform. The peak current, background current, rise time, fall time and pulse frequency all affect the voltage. The exact voltage for a given wire feed speed can only be predicted when ...

    STT WELDING The pictures illustrate the wave shape of current for the process. They are not drawn to scale, and are intend- ed only for the purpose of showing how the variables affect the waveform. T rim in the STT mode adjusts the tailout and back- ground portion of the waveform. T rim values greater than 1.0 add more energy to the weld and make t ...
