Pulsed GTAW for stainless steel - The Fabricator

Setting ParametersVariables and Their EffectsIncreasing Travel SpeedConclusionsTo improve productivity and quality effectively, the arc must pulse at frequencies from 100 to 500 PPS. Note that achieving these While the actual mechanics of setting pulsing variables can differ depending on the brand of equipment, the variables tend to be the same or similar on all machines peak amperage, pulsing frequency, peak time, and background amperage. Suggested parameters for welding any of the 300 series stainless steels, whether pipe, tube, or plate, are 1. Peak amperage. Set this as you would See more on thefabricatorWelding austenitic stainless steel - The Fabricator (steel) A current setting that is too high or a travel speed that is too slow can contribute to this problem.
