Features
- Red Sail X700
- 60 watt
- Water cooled
- 700mm x 500mm cut area
Safety
- Never let the machine run unattended especially when its cutting!
- Always use approved materials. Some materials can release chlorine gas or catch fire.
- Remember to pull bed leveling knob before running a job.
- Run the machine with the interlock on. The interlock is a key switch that will override the option to turn the laser off when the door is opened.
If a fire Occurs
- Immediately stop the laser, this will more than likely extinguish the fire.
- If fire still exist, try to blow it out.
- If fire still exist, spritz it with the water bottle. Notify the board.
- All else fails, use the fire extinguisher. Notify board.
Testing Plastics for Chlorine
A blow torch and copper wire will be needed for the test.
- With a pair of pliers heat up the end of the copper wire and burn off any residue.
- While still hot, touch a sample piece of the plastic you would like to cut with the hot end of the copper wire.
- Place the wire back into the flame and burn the plastic. If the flame is blue/green the material is not safe and will emit chlorine gas when cut.
