I regularly weld 3/8 inch and better steel at 25.5 v and 355 ipm. I was wondering if changing the inductance settings will have the same effect at that voltage and wire speed. Thanks.

The primary purpose of the inductance options are for selecting between short-circuit, globular transfer, and spray-arc welding.

The Lincoln CV305, for example, has two options, selected by where you attach the ground to the machine. The low-inductance setting is preferred for short-circuit GMAW. The high setting is for globular xfer and spray-arc. If your machine has an inductive mid-range, you can assume what the additional division is.

As long as the setting you're using matches the process you're doing, you won't get any improvement by changing. I have played with this on the CV-305. Moving to high-inductance (when I MIG, it's all short-circuit, as it's rarely flat), I found harder starts, with more spatter at the start, and a longer arc-stabilization time.

The info on the CV-305 comes from here:

The rest is personal experience.

I've noticed higher inductance seems to have less of a crown I'm using a mm 350 p miller could just be me though!
