I just learned a very crappy lesson.
My spot weld holes are too big and I'm burning my new metal.
My mig won't work well in the lowest setting.
I have the wire speed up max and on the 2nd setting it's an .035 wire only millermatic 35
Piss me off.
I'll fix it or just put some light weight carpet in.
From now on I'm using a 1/16 drill bit.
Ive found on my millermatic 211 and other small welders that the wire speed adds a percentage of voltage to the weld. Keep the power the same and turn your wire down and try it.
Edited to add, from weldingweb forums;
Wire speed tracking is where the wire speed increases or decreases as VOLTAGE control is increased or decreased in order to help the operator stay within the weld parameters when making voltage changes.
