    Bigger is better. If you can get the tungsten to the joint, use it. I use a #8 most of the time. Hobby guy without a clue.

      According to the Miller Dynasty manual it should be at least 3 times the size of the tungsten........1/16 tungsten, 3/16 cup diameter.
      I agree bigger is better on the cup size and I also use a #8 most of the time..

            It seems like I always use a #6 cup and 3/32 tungsten with about an 1/8th stickout for almost everything.
            When I was building ambulances almost everyone was using #5's with 1/8th tung and flush!!! It was wierd but after I got used to it I got good with it. That was a syncrowave 250 and running between 150 and 225 amps normally. You could get in and out of tight spaces fast with that set-up for sure.
            I really rocked there little world because that was when I found this forum. I started tapering my tungsten with the drill and at the time switched to ceriated.
            I have bigger cups, but it seems for outside usage they are next to worthless if there is even a slight breeze. When I get back indoors I forget that I could go up in size and get better results. Just lazy I guess...oh well.
