I am running a Lincoln DC-600 with 5/64" Dia NR-212 wire at 18 Arc V and 75 in/min wire speed welding 1/2" HRS to 3/4". 95% of the time the welds look great....but then the wire wire "stubs" and spatters and jumps and it is hard to get a good looking weld. Have tried to run "steady", keep the wire in the puddle, put the ground clamp directly on the parts being welded, reduce the stickout, etc.....with little success. Any suggestions or other things to try??

What kind of stick-out (contact tip to work distance) are you keeping? This is where it is nice to have a voltage sensing feeder. It is important to maintain a consistent stick-out or it can "stub". Maintain about a 1 inch stick-out. Hope that helps.

Have been running the recommended 3/4" ESO but sometimes decreased to 1/2"
