I guess you don't know that your MM180 is rated at the same amp & duty cycle as that spool gun.
If your welder won't do it then the spool gun won't either.
To say "yes" this spool gun will weld 1/4" material then yes it will.
Here's Millers picture to show the thickness of material both units will weld.
