CALIBRATION SPECIFICATION

Wire Feed Speed Validation:

Calibration of the POWERBrazer may be required
when the printed circuit 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.

Tools required:

• RPM meter
• 7/16” open end wrench.

To verify if calibration is necessary:

1. Turn power OFF.
2. Set the wire feed speed to 100 in/min.
3. Remove the plastic cover from the lower portion

of the wire drive with a 7/16” wrench. 

4. Turn power ON.
5. Measure the motor rpm when the COLD FEED

button is pressed.

6. Verify the rpm is within 16 – 19 rpm.

WARNING

SAFETY PRECAUTIONS

MAINTENANCE

To change the wire feed speed calibration:

(See Figure D.1)

Tools required:
