Introduction

The term Machine Torch refers to a 3-hose or 2-hose oxy-acetylene torch nozzle that is used on automated CNC torch cutting tables. The 3-hose version features automatic oxygen blast, engaged via a solenoid. The 2-hose version requires manual toggle of the oxygen blast.

Add flashback arrestors to the regulator, as the machine torch typically does not have flashback arrestors. [1]
