Harbor Freight Plasma Cutter Retrofit for CNC Router

[jurban]

Hello,
I photographed the process of tapping into the trigger circuit for a Harbor Freight plasma cutter so that I could control it through my CNC router. The goal was to make the trigger non-permanent so that I could remove it from the CNC router and use it by hand. I then connected it to a relay board to isolate it from the controller. It works very well.

Here is a video of the first test: [nomedia="http://www.youtube.com/watch?v=BueblmPQCOg"]YouTube- Torchmate + Harbor Freight Plasma Cutter Test[/nomedia]

Comments for improvements are appreciated.

I have a quick question about using a Harbor Freight plasma with a Torchmate 2x4 system. Does the air cooling on the torch interfere with the cutting sequence. If so, does anyone know how to disable the air cooling feature on a Harbor Freight plasma unit.
Any help or past experiences would be appreciated.
