Newbie shopping for mig welder with questions

What size of tank should I get for a Hobart Handler 140 Mig? The main purpose of this mig welder will be to do some patch panel repair on an old chevy pickup.

You would probably be fine with a 10lb tank.

A 80 cubic foot cylinder will give you 4 hrs. of straight welding @ 20 cfh flow, a 60 CF is about 3 hrs. A 10lb tank sounds like straight CO2? You'll get cleaner welds with AR/CD mix, just a thought!

Get the biggest one you can afford.

I just use straight C02 in a 25lb cylinder that lasts seemingly forever, probably 40-50 lbs of 0.035 wire.
I started out using a 20cf cylinder of c25 mix, but it only lasts about 5-6 lbs of 0.035 wire.

Straight C02 works well and does produce good welds, but c25 is a tad better.
