I should have added that the fuse has F2A250 stamped on the side of one
of the caps. It seems to be for protecting the little 12v. wire-feed
motor. At least, without the fuse the welder powers-up fine, but the
motor doesn't run.


You have answerd your own question :-)
It is a 2 Amper fuse. (glass-tube)

And i asume the 'glass-housing' is 6X30 millimeter.
or it can be the smaller housing ( 5x20millimeter)

"250" means that it is suited for breaking 250 Volt. Do not pay any
attention to
this parameter. The parameters to apply whit is the HOUSING & AMPERAGE.

Take it whit you to a gas station and i'm sure they have one for you .
(bring along the old fuse! )
