Welding

[Guest snowy2]

Better to buy the bigger bottles. Gas choice can affect what metals you can weld. For aluminium some folks use pure helium. I just use pure argon for steels.

Hobby weld do good sized bottles at a good price.

You "could" use a hobby bottle but then you really are into the minutes of welding per bottle territory. TIG welding uses far more gas than MIG welding because it's a slower process and then there's post flow etc.
