Hi Forum!

New here, great place!
I need help with my Sievert beginners torch.. I have been buying parts for it recommended by my teacher and I'm now confused with what works and what doesn't. I have a flashback and a two bar regulator that fit together, however I have to take the piece off that it came with (the piece with the black button on its end) Is this right? Could I just use what was sent in the beginners kit? Do I need a flashback and 2 bar regulator with the third piece also? Doesn't all go together and seems clunky and not correct!

Thanks, I am getting so confused.
