Does any ones welder skip some metal thicknesses when setting up for mig? Mine skips over 5/16 and some thinner gauges. Happens on all wire size settings.

What do you mean ? "skip some metal thicknesses"

[danike110]

There’s presets, 3/16, 1/4, 5/16 etc. mine jumps from 1/4 to 3/8

Does it do this with every wire size?

You need 3 settings. Thin, medium and thick and mark your chart. That little machine could be on thick or where its wide open a good share of the time. There aint any good way to describe in a chart what the welder learns from experience and training. Just cause its set to weld thicker doesnt mean a guy cant weld thinner faster so a 030 compact I am wide open much past 16 ga and for sure at 10 unless we got a big ole hairy crack in it. I tend to find myself turning it down a little more than I used to on thinner and am going to get a 140 onme of these days for small wire.

I can turn my 180 up more , squeeze a couple more A out of it but the arc turns to crap. On the top end no matter what that chart says, there aint no mo.

My Miller Multimatic 255 has settings for 24 gauge, 20 gauge, 18 gauge, 14 gauge, 1/8, 3/16, 1/4, 3/8, and 1/2

Its up to you to dial in the right settings for "in between" metal thicknesses. I am not surprised that the Omnipro is the same way.
