Gas leak on new 251 machine question

[s-on]

For the Techs I have a new millermatic 251 and using Liquide airs ALMIG
is it normal for the Gauges to zero out over night ?(Tank shut off) or do i have a leak worth searching for and where would the most suspect leak area be ??

s-on,

Welcome aboard.

My MM 135 and 210 do the same thing. No biggie. If you look at the gas lines and connections from the solenoid to the MIG gun, they are just vynil hoses with push-on terminations. No clamps. If you are not blowing shielding gas audibly when the trigger is released, all's well!
