Oxy-acetylene Torch
Source for the torch: http://www.dynatorch.com/OxyFuelKit.htm
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]

The XS-3535/8S-4 Stepper Driver is a 4 axis pulse-width-modulated (PWM) current controlled bipolar micro-stepping controller.
Each axis drive has a +-2.5 Amp/phase @ 35 Volt maximum continuous Output Rating. The drive circuitry has thermal shutdown protection and crossover-current protection. Synchronous rectification circuitry eliminates the need for external clamp diodes in most applications.
Each axis accepts Step & Direction signals, along with 2 jumper inputs to define microsteps per full step.
The board is of 4-Later construction with Isolated Power and Logic supply planes. The drive circuitry has a heat sink attached to allow cooler operation.
