welding inductance question

[sewerzuk]

I just bought a Linde VI-200 power supply today. I'm an experienced stick welder (in that I've been doing it for a LONG time as a hobby) but I don't have very much experience with different machines. I spent most of my time behind a cheap Craftsman AC stick welder, no industrial machines. My question is this: My Linde welder has an inductance control. I'm guessing that this is kind of a variable AC output (the higher the inductance, the lower the output frequency) instead of the 2 separate jacks for AC and DC outputs (with diodes). Am I on the right track? Anybody have any advice on where this should be set for welding on different materials/thicknesses/angles/etc.? I have a MIG gun and wire feeder for it, so I'll be doing mostly MIG welding on mild steel...but until I get the bottle I'll be using up my pile of 6011 rod. Looking for a spool gun for aluminum too...any recommendations there?
Thanks!

I don't think you're on the right track.

Inductance control for a CV machine (you're referring to a MIG gun), is to control the relationship between the arc on/arc off time. You can control spatter and get more wetting by adding inductance. This will cause the arc on time to be longer in relationship to the arc off time, which of course is where the wetting comes in: the puddle stays hotter and wets out the bead a bit more.
