This torch has two torch heads. The top torch is a premix torch (for a hotter flame). The premix tip is interchangeable and you can use any of our premix tips. Comes with a #3 premix tip and a 10 holes with one larger center hole tip.
The lower torch is a 45 port, round torch head with a single center port, a ring of 16 ports, then a ring of 27 ports. Flame width up to 1-1/4". We recommend using a flashback arrestor with premix torches. Use 3/8 hose.
