3.3.12 Calibration of the wire feed speed
When factory settings are used, the wire feed speed can be adjusted to between 4 and 100
without a unit of measurement. Only the LED symbol indicates that wire feed speed is the
parameter to be set.
The unit of the wire feed speed (m/min) is shown once the wire feed speed of the device has
been calibrated. To programmatically calibrate the wire feed speed:
1. To prepare the welding equipment for calibrating, do the following:
• Connect the wire feeder to the power source with the control cable.
• Insert the filler wire in the gun, and run the wire out of the contact tip.
• Adjust the feeder wheels so that they are sufficiently tight.
• Start the power source and turn on the control panel with the start button, P1.
2. Depress button P7 (SETUP) for at least five seconds. The set-up menu appears on the
display.
3. Select the calibration menu (CAL) by rotating the left-hand knob, and then select the
value ’Enter’ (Ent) with the right-hand knob. Accept your selection by pressing button
P10 (REMOTE/LOCAL) briefly.
4. Use the right-hand knob to select ‘m/min’ as the value of measure for the quantity to be
calibrated, and accept your selection by briefly pressing button P10 (REMOTE/LOCAL).
5. Use the left-hand knob to set the lower calibration point to the desired value (e.g., 2.0 m/
min).
6. Cut the filler wire at the contact tip end. Press the trigger, and let the wire run until it
stops automatically. If the wire is not moving when calibrating the lower point, increase
the wire feed speed value, e.g. to 4.0m/min.
7. Measure the length of the loose wire end to an accuracy of 1 cm.
8. Enter the measurement with the right-hand knob, and accept your selection by pressing
button P10 (REMOTE/LOCAL) briefly.
9. Use the left-hand knob to set the higher calibration point to an appropriate value (e.g.,
