1-TORCH INSTALLATION
3A-14 HyPerformance HD4070 Instruction Manual
Torch breakaway kit (optional)
If not installing breakaway kit, go to page 3A-16
Install the torch breakaway kit as follows. Refer to figure on next page.
1. Mount the fiberglass bracket to the X-Y lifter with 4 hex screws.
2. Mount the breakaway to fiberglass bracket with 6 screws.
3. Attach the torch mounting block to the breakaway with the collar and 2 screws.
4. Connect 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 6.9 bar (100 psi) (recommended maximum pressure).
8. Adjust the regulator to indicate 2 bar (30 psi) (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 10.2 bar (150 psi). Typically, the maximum inlet pressure
should be set at 6.9 bar (100 psi).
• 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 must be manually repositioned when air
is applied. The breakaway will not rest in its position after air pressure is lost.
