Once you get the MIG welder, you will find a whole lot of things for it to
do!
There are two types of MIG welders, those that have a gas bottle in them and
those that don't. Get one that has the bottle as you can always use the
wire with the built in flux but you can't go the other way around.
You will quickly find that cutting metal is going to be a long haul with the
hack saw so you might as well then get the power hacksaw (you know, one of
those things that drop down on the work in a jaw and gradually work their
way through) as a second tool.
