I have found that keeping the gun lead as straight as possible fixes this problem. Also it is sometimes recommended to use one tip size bigger when welding with flux core wire. My last spool was radnor flux core wire .030, and a .035 tip keeping the lead as straight as possible and it welded extremely well. If that doesn't solve it you should take everything apart and clean it / blow it out with compressed air.

bad computer-its an authorized dealer thing-you can pay 1-200 to get it figured out or buy a HF flux core welder for same price.

yeah-Im all blue in my shop and I said HF...

i would pay the miller dealer to get it fixed.

Sound like you have a bad trigger on the gun. Does gas spray when you pull the trigger? Check the wire plug that goes from the pistol to the unit. It should be under the liner hose where it connects to the machine. Then use a voltage meter on the wires going to the drive feed motor, and see if you get current when you pull the trigger. If gas doesn't spray neither, sounds like you got a bad trigger switch

The first thing to check would be to see if you have open circuit voltage at the weld output terminals when you push the pedal. Make sure the high frequency is off if you are going to to check with a multimeter. After that if you do have OCV but no high frequency to start the arc, try it in start and in continuous. When you put it in continuous it bypasses a control relay. Also check the HF points to make sure they are clean and gapped to about ten thousandths.
