ACTIV8™
CALIBRATION SPECIFICATION
Calibration of the ACTIV8™ may be required when
the p.c. board, wire feed speed potentiometer or
motor is replaced or serviced. Calibration matches
the scale on the name plate to the actual wire feed
speed.
To calibrate the ACTIV8™:
1. Turn power OFF at the welding power source.
2. Remove the spool of wire from the feeder. Remove
the gun from the feed plate. Remove the plastic
case from the center panel assembly. (See Figure
D.1)
3. Connect the ACTIV8™ to the constant voltage DC
power supply capable of supply at least 9 amps or
welding power source. Connect the electrode to the
“+” positive terminal and the work clip to the “-” neg-
ative terminal. Set the CC/CV switch to “CV”.
4. Attach the gun trigger to the 5 pin amphenol at the
front of the feeder.
5. Open the wire drive pressure arm.
6. Adjust the WFS knob to 50 IPM. Activate the gun
trigger connected to the wire feeder.
7. Measure WFS. If reading is 49 to 51 IPM, proceed
to step 8. If not unplug J3, insert shorting plug into
Control PC Board J3 (shorts pins 4 & 8), and adjust
WFS knob to 49 to 51 IPM and remove the shorting
plug.
8. Set WFS knob to 300 IPM.
9. Measure WFS. If reading is 297 to 303 IPM, pro-
ceed to step 10. If not, insert shorting plug into
Control PC Board J3, and adjust WFS knob to 297
to 303 IPM and then remove the shorting plug.
10. Set WFS knob to 800 IPM.
11. Measure WFS. If reading is 795 to 805 IPM cali-
bration is complete. If not, insert shorting plug into
Control PC Board J3, and adjust WFS knob to 795
to 805 IPM and then remove the shorting plug.
12. Release the gun trigger.
13. Turn power OFF at the power supply or welding
power source, and reassemble.
