So you'll probably want either the X3-B (Extreme)

Or the WSF-4 (Sof-flame)

The X3-B heats faster. The WSF-4 is slower, but some guys prefer it as it's harder to accidentally overheat. Both are for B tanks

You can check your local supply houses. They should have them, but check their price vs Amazon. Amazon sells cheaper than a lot of supply houses (for TurboTorch)

As others have mentioned, if you can get your boss to pay for it, that would be ideal

But realistically, not every employer will do this. Up to you if you want to look for a new company as an apprentice, based on that
