WIRE FEED SPEED KNOB
Wire Feed Speed, CV Operation
When Across the Arc models are operated with CV power sources, the wire feed speed will remain a con- stant value, independent of arc voltage changes, as along as the arc voltage does not drop below the val- ues per the following table.
83% Wire Feed Speed
The 83% wire feed speed reduces the wire feed speed to 83% of the original set value when activated. For example, if the original wfs = 200 in/min, the feed- er will regulate to 0.83 x 200 = 166 in/min.
The 83% trigger requires a gun with a dual procedure switch.
This feature is often useful when welding pipe, and a “cooler” procedure is required on the bottom portion.
