Go to the Miller website, Service section [Here], plug in your Serial Number in the left box, and it will show the link to your correct manual down below.

You might also operate all the controls, such as those for the Spot/Stitch panel, a few or more times to be sure they're making good contact inside.

Just curious; what is your welding background and what other machines do you have or have you used? Any interesting projects or other facts to introduce yourself with? :waving:

 

So I suppose if the Miller website just lists the March 1987 and the January 1989 Manuals I have to make due with that. My welder serial number is much closer to the later manual, and has the 2 wire drive motor and motor speed control board like the later manual. I guess I will have to cut and paste and make my own Manual.

I have played with the Spot/Stitch/Continous controls and can hear the timers working. I was just trying to simplify the setup to see the cause of the wire feed motor not working. I pulled off the two wires feeding the motor and there is no voltage going to the motor when I simulate the trigger pull. The wire feed motor spun when I hot wired it off a 18v lithuim Ion drill battery, So I am thinking it somewhere in the relay / bridges or control boards.

Oh, I make metal sculptures off and on for the last 20 years. I have a couple of plasma cutters, oxy acetylene torches and I use to teach classes.

 

try the miller web site. they usually have manuals available
