strange MIG wire feeding/operation issue

Just recntly switch to an other brand or mig wire and ran across some weird feeding issue.

when the wire exits the tip of the gun (during welding), it tends to wobble or point to random direction, there for making the bead look ununiform. installed new contact tip .030

wie ERS70-6, standard mig wire. Electrode stick out is 3/8-1/2 " wire .030" solid mig machine millermatic 210 setting 4/60 gas C25flowing 25 CF/H

I normaly run hobart brand in the past and never had this problem

what can cause such thing? all setting used were the same, ran out of the hobart brand, stopped welding and slammed on this new wire "US Steel " continued.welding.

can it be some junk wire?

I will try to reverse the spool, but it seems un normal upside down

I've always ran it this way O____ also it goes throug a 12 foot gun/liner, you would think it qould unwind by then.

The wire (sticout) tends to roam in random direction.

the only thing I see different on the labes is HEAT , Hobart is 1585 this one is 1404, but it could be brand related rating

the brand is "US forge" .

Have you tried to see what happens if you put it back? How about the wire diameter? Suggest checking with a mike to see whether it is undersize. Is it possible that when you threaded the new wire you accidentally pushed in a little lint or dirt, causing the wire to stall and buckle a little bit?

found the problem , the wire diam is inconsistent, I pulled the fingers along a fresh wire and I can feel increasing and decreasing in diam. the wire it self may be wisted on its axis.

The problem is in the wire that have endured many deformation when it has been constructed too much pulled change the coil and all it will go to place. acrobat ants ha scritto:
