Correct Engine calibration should be performed on the Millermatic 350P welder.
The Millermatic 350P MIG welder can handle material up to 1/2-inch thick in one pass. The Pulsed-MIG process switches from high to low peak current Thirty to Four hundred times per second for welding aluminum and stainless steel and can improve productivity with all types of welding. The Millermatic 350P welder features an automatic motor calibration function that should be performed after replacing the wire drive motor or the control circuit board.
Instructions
1. Turn on the 350P welder. The unit should power up in MIG welding mode; if not, press the "Setup" button twice to illuminate the "Process" light, then rotate the right knob until "MIG" is displayed. Press "Setup" repeatedly to exit the setup process. Leave it in MIG mode for the most accurate calibration.
2. Open the drive rolls in the welding power source and in the push-pull gun, if one is attached, to prevent wire feeding during calibration.
3. Simultaneously press and release the "Setup" and "Arc Control" buttons. Rotate the left knob until "MCAL" is displayed. Rotate the right knob until "YES" is displayed. The unit is now in motor calibration mode.
4. Release the trigger and "DATA SAVE" will appear in the display while the calibration data is stored in the control board's memory. When this display clears, close the drive rolls in the welding power source and the push-pull gun, if attached. Calibration is now complete.
Press and hold the gun trigger. The wire drive motor will run at Fifty inches per minute for Twelve seconds, then at Eight hundred inches per minute for Twelve seconds. Continue holding the gun trigger until "CAL DONE" appears in the display.5.
