Miller Auto Deltaweld 452 has permanent weld output and the A22 wire feeder stays on at full RPM when the machine is turned on. We use this welder for basic MiG welding.

SOURCE: what setting do I need to weld aluminum for a 135 miller mig weld

start slowly turning up the wire feeder,and the amps till you get the sound of bacon crackeling and youll know your there. hope this helps jojogunne

SOURCE: Lincoln 135 PRO MIG Welder feed stops after a few minutes

1/4" plate with a 135 amp machine is probably beyond it's duty cycle abilites. If you are using a mixed gas, and pushing the max on the settings, it will be cutting out because it is designed to.
You might want to get a higher amperage welder for consistent welding of 1/4"
The 140 Pro maxes out at 5/16" using inner shield wire. and 1/8", or 10 guage with gas.

Hi Kevin,
Causes of poor penetration: Travel speed too fast, welding current too low,
poor joint design / and or preparation, electrode diameter too large,
wrong type of electrode, excessively long arc length.
Solutions: Decrease travel speed, increase welding current, increase root
opening or decrease rootface, use smaller electrode, use electrode with deeper
penetration characteristics, reduce arc length.

This usually happens when the main Power semiconductors fail. You need to check out the two main places, the Power Supply, make sure ALL voltages are correct, and the main Output semiconductors, check these to make sure they are Not open circuit or short circuit.
