Well, I've been practicing and experimenting with my HH175 and I think I'm starting to get an "idea" of what settings to use.

I also got some books from the local library, and the Miller education kit and have been reading about GMAW.

So I understand that a higer wire speed will result in a higher amperage, but what do the numbers on the dial of the HH175 wirespeed knob represent? It's not IPM, it can't be Amperes since the machine accepts different wire sizes -- but I can't figure it out.

I know that there is a chart in the door to tell me where to set it, but I'm trying to understand the process, and I'm struggling to figure out what the numbers printed on my machine translate to in terms of wirespeed.

I guess, similarly, if someone can answer that for me, they could probably tell me what voltage the transformer taps 1,2,3&4 correlate to?

Thanks!
