Having trouble with wire feed when the temperature gets warmer outside, stops feeding wire once in a while, gets worse as the day goes on. Changed the feeder, power supply, lead, torch, water cooler, ground cables, cable from the power supply to the feeder. Any ideas? Thanks

How does it stop? Does the feeder just fault out or quit? Or does the wire bind up somewhere in the feed tube? The nature of the failure is key to determining the root cause.
One thing I notice you didn't list changing was the feed tube/liner passing through the robot dressing (from the robot base to the torch). This tends to be a primary failure point, since the jacket wears over time, plus the additional stresses caused by robot motion. When I see feed failures, that's often one of the first places I look.

Yes, also changed the tubing, changed everything could possibly change. It just stops feeding wire. And only when it gets warmer weather.

With no errors?
Does the wire bind up physically somewhere and resist being pushed? Or does the feeder motor simply stop turning?
If the fault is really temperature-related, my first thought is thermal expansion somewhere. My second is that something is overheating, but that should generate a system fault message.

Not binding, no error. I don't get it at all.

When does it stop?, if it's during welding does the wire move out or back in when released?, or does it just not respond to a wire start (weld on) command?.
