54. 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 CV OPERATION THERMAL LED MOTOR OVERLOAD The thermal light illuminates when the wire drive motor draws too much current If the thermal light illu minates the wire drive will automatically shutdown for up to 30 seconds to allow the motor to cool To start welding again release the gun trigger inspect the gun cable liner and conduit Clean and make repairs as necessary Start welding again when the problem has been safely resolved For best results keep the gun cable and conduit as straight as possible Perform regular maintenance and cleaning on the gun liner conduit and gun Always use quality electrode such as L 50 or L 56 from Lincoln Electric LN 25 PIPE LINCOLN P B 4 OPERATION B 4 POWER UP SEQUENCE All of the LED s will briefly illuminate during power up If the gun trigger is activated during power up the feeder will not operate unt
