Had an issue with an Axcess e power supply/feeder yesterday. Operator was welding and the wire feed rate would slow down and speed up. Sometimes it would slow and then quit feeding wire completely.
Maintenance changed out the e feeder before I got there. With the feed rolls disengaged, we would press the jog and watch the bottom set of rollers. They would start slow, go slower, and then speed up. Checked wire pull through liner to the feeder - good. Checked roller size and wire size - correct. Inserted a new liner in the stinger/gun - even though the wire pulled through fine. Switched the cable that connects the feeder to the power supply with one from a station we knew the welder was running correctly. Still wouldn't run correctly. Swapped out the power supply - which a Miller tech from hotline told me to try. Nope. I checked program set up on the feeder - correct. Lots of head scratching going on the whole time. Finally decided the only thing we hadn't changed was the stinger/gun itself. Got a brand new one hooked up. Welds better than it did before.
Any thoughts on why this would be the gun? Anybody else ever see this and how did you fix it? What bothers me is that it took us 2 hours to get the op welding product again. Need more training so I can diagnose issues faster.
Thanks.
