Phil, the wire feed rollers appear the same as on my Millermatic 200......you have a .023 diameter wire set and a .035 diameter wire set.
The small tip could be from same welder depending on brand of mig gun that's on welder.
The other two 'tips/guides' I don't recognize.......
Mine is a Miller200 also!!!!!
I have a friend who wants to buy it so I àm having the distributor check it out so everything works.
This forum has the GREATEST knowledge on earth!!!!!!
