STALL FACTOR - an adjustment on the POWER MIG ® 350MP that allows the welder to adjust the maximum amount
of power going to the rear drive motor. The purpose is to send only enough power to the rear drive motor to pull the
wire off the spool and get the wire up the torch liner.
STALL FACTOR NUMBER ADJUSTMENT
1. Turn the POWER MIG ® 350MP off.
2. Hold the Push-Pull Torch trigger in and turn the power back on. Continue to hold the trigger in while machine
powers up.
3. Once the machine displays "SF" in the left display and a number 5 to 35 in the right display the trigger can be
released.
4. Use the volts / trim knob to adjust the Stall Factor Number.
5. Once the Stall Factor Number is adjusted push the select switch up.

the SF number was not changed.
