Description
This is used to calibrate the wfs meter to a known calibrated
wfs meter. 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:
Actual WFS / Set WFS = Calibration factor
Example: 405 / 400 = 1.01
This is used to calibrate the voltage meter. To calibrate the
arc voltage display, before entering the setup menu:
• Determine the ratio of the actual arc voltage and the arc
voltage displayed.
While in the setup menu, adjust the calibration factor as
follows:
Actual arc voltage / displayed arc voltage = calibration factor
Example: 20.0 / 20.5 = 0.97
This is used to calibrate the current meter to a know
calibrated voltmeter. To calibrate the arc current display,
before entering the setup menu:
• Determine the ratio of the actual arc current displayed by
the power source and the current displayed by the wire
feeder.
While in the setup menu, adjust the calibration factor as
follows:
Power source displayed arc current / Wire feeder displayed
arc current = calibration factor
Example: 205 / 200 = 1.03
