WFS Calibration
To calibrate the wire feed speed, before entering the set-up
menu:
• Set the display to the desired wire feed speed (example: 400
inches per minute)
• Measure the actual wire feed speed (example: 405 inches per
minute)
While in the set-up menu, adjust the calibration factor as follows:

Left Display Selection
The left display can show either amperage or actual WFS during
welding. Note that actual WFS is not the same as preset WFS. For
example, the preset WFS may be set to 400 ipm, but the arc
voltage is only 15V. The actual WFS will be approximately 280
ipm because there is not enough arc voltage to run at 400 ipm.
To change the left display reading:
• Rotate the WFS knob to the left to display amperage (current).
• Rotate the WFS knob to the right to display actual WFS.
