Miller 350P push pull with 0.9mm al.wire

[miro]

I got Miller 350 P (push pull machine) with 30" long cable and XR 30A gun.
I have no problems with any thicker wire...like 1.2mm and bigger but when I try (0.35)- 0.9mm wire does not come out very smooth, and it often jams. I got proper rollers on and all settings..and cable is never tangled ???I tried different tension but it is the same..I use big spools at all times..
thanks for your input.

2 things come to my mind right away. I know you said that you have all the right settings and all, but a common problem with the 350P and .035 (9mm) wire is the drive roll tension. Make sure that the drive roll pressure on the front drive roll pressure to 1 and the rear drive roll pressure to less than 1. Next make sure the hub tension is loose.

Also if you have had birdnesting problems there could be a piece of wire lodged in the torch liner. I have seen this more than once. In which case you will need a new liner and they are not all that cheap.

i use this same set-up when i have had to send the xmt304 to the shop. at first the wire feed was erratic at best, and just as jws said, i adjusted the drive roll tension and loosened the hub tension. all was well after that. i ran 4 16 pound spools through it before the xmt got back. also, are you using 4043 or 5356 alloy? the 4043 is harder to feed since it is a softer alloy.
