welding gage question
i have a mm212 with a bottle of Ar/Co2 mix. the stock valve, smith, that came with it seems to have failed, at least partially. on the high side the gage seems to show the bottle psi, on the low side the gage is off the scale to the high side. i'm not sure if there is psi in the line to the gun or not. i didn't realize the problem until i tried to lay some welds and they looked worse than my normal, unskilled welding ability would lay. looked like a lot of swiss cheese.
i have these two sets of gages that i had rebuilt about a yr ago, haven't used them yet. would either, or both, of these be ok to use with my miller?
