How to Calibrate a Miller Welding Machine

Turn the welder on and press the "Setup" button two times so the display reads "Process." Turn the right knob until you see the "Setup" option.

Open the drive rolls on the power source. Press the "Setup" and then "Arc Control" button together on the display panel.

Rotate the left knob until you see "MCAL" on the display. Turn the right knob until you see the "Yes" option. The welder is in calibration mode now.

Press down and hold the gun trigger until you see "Cal Done" on the screen. Release the gun trigger to save your calibration.
