Torch breakaway kit (optional)
Install the torch breakaway kit as follows. Refer to Figure 3-5.
1. Mount the fiberglass bracket to the X-Y lifter using the 4 hex screws.
2. Mount the breakaway to fiberglass bracket using the 6 screws.
3. Attach the torch mounting block to the breakaway with the collar and 2 screws.
4. Wire the electrical output of the breakaway to the emergency stop circuit at CNC.
5. Mount the filter/regulator.
6. Connect tubing between regulator and breakaway.
7. Install air supply to the regulator inlet port at 100 psi (6.9 bar) (recommended maximum pressure).
8. Adjust the regulator to indicate 30 psi (2 bar) (recommended starting pressure) on the gauge.
9. By hand, force the breakaway to trip to simulate a crash.
Manually reposition breakaway to the lock position.
10. Adjust air pressure until the desired trip force is achieved.
11. Enable the emergency stop circuit at CNC after the breakaway is installed.
Notes:
• Installing the torch breakaway kit to the X-Y lifter assembly also requires using parts of the torch mounting block kit
of the proper diameter. Refer to Section 6, Part List for details.
• The maximum pressure regulator inlet pressure is 150 psi (10.2 bar). Typically, the maximum inlet pressure should
be set at 100 psi (6.9 bar).
• The routing of the leads, stall force, IHS speed, and acceleration/deceleration movements can affect the pressure
setting required to achieve reliable operation.
• If air pressure is removed (for example, overnight), the breakaway will have to be manually repositioned when air is
applied. The breakaway will not rest in its position when air pressure is lost.
