wire speed accuracy?

[WeldMore]

I had similar results as Kevin except for the 100 ipm setting
100/110
200/150
300/212
400/268
These results were in Standard mode, not Syn mode.
In Standard mode I would want the welder to accurately follow the panel settings. This allows me to accurately adjust based on metal thickness too.

Agreed that feed speed when not welding is not relevant. So I put together a new test that measured the drive roller speed while welding. That was then converted to wire feed speed. (see photo).
On the right side of the photo is the drive roller with yellow mark to monitor its rotation. I made a video while welding so it could record the drive roller rotation and the stop watch simultaneously. I viewed it in frame by frame mode so I could measure the time for each rotation of the shaft. The volt meter is measuring the gun voltage - I put a simple RC circuit on the meter to take care of the noise and any minor variations.
The chart attached shows that the wire feed speed is about 25% faster than the speed as set in Standard mode. The exception is at 400in/min. But I also noticed a lot of rotation speed variation at that speed. Will probably redo that.
The voltage runs about 10% higher most of the time.
Overall I am pleased with the welder (I only tested MIG welding) but I was hoping the settings in Standard mode would be more accurate.
