Default Lincoln 255c trouble?

I bought a lincoln 255c new in march. It worked great until about july and I had trouble with the wire welding itself to the tip. Not a bit problem but it got worse up 40 times in one day. I tried new tips,new wire, (old stuff was rusty in 4 months) and adjusted the wire and voltage etc. I took it into the dealer they checked the swithc board, put a new liner in, and a new nozzle. It seemed to work alot better. I drug it out yesterday and it wasn't welding right. It acted as if it wasn't getting enough wire. Which was odd because i went by the chart before and it welded perfect. So i turned the wire speed up and it would weld alright and then gasp for wire. It keeps surging as i try to weld. I had a hell of a time convincing the people at the dealer acted as if i didnt know how to weld. I laughed and got pissed off and said I have a L-tec mig at the school that is over 16 years old and I have never had this much trouble and this welder is only 4 months old. I do know I am about out of gas, I know that would make poor welds(porosity) But they will usually weld consistent. I am confused and feel ripped off.
Help

I would look at the drive rolls when it is trying to feed the wire. Are they slipping or is the drive motor actually surging? Get it fixed and sell it.

Since he had such good luck with L-tec he should buy Yellow!!!

It can also get rust from that dirty wire up in the diffuser and drag on the wire.

Sounds like a liner/tip/wire problem. Sometimes the liner can get kinked witout you knowing, or have wire that is rusty/dirty etc. If it is consistantly bad, I would switch the tip, liner, and check the wire for debris and think of putting on a new spool of a different brand of wire. If the problem persists take it back to the shop and throw a fit.

I have found that changing every thing from the drive roll forward usually solves all my feeding problems. I have been wanting to get one of the wire cleaners I saw BigRig post, but I haven't run across one yet.

They put a new liner in it a new tip, we switched brands of wire, I maybe ran 30 minutes since it was fixed it did good and I put it away for two months and it is acting up again.
This bothers me
