Ross Mig Welding Disposable Gas Bottle Argon I/N 6320518 | Bunnings Warehouse
Says "approx 20 minutes". But these look like roughly 1L @ 60 bar. My understanding is that's only 60L at atmosphere pressure. What gas rate do you use on a MIG?
10L/min = 6 minutes.
5L/min = 12 minutes.
Someone check my math...... but if that's right, it sounds damn expensive for $40!
