Arc Response Technology
Arc Response Technology™ lets the plasma cutting system adapt to problems at the torch that can cause decreased consumable life or possible torch damage.
Automatic ramp-down error protection
For LongLife® technology, a controlled stop of the current and gas pressure is necessary for protection of electrode life for mild steel cut processes. A failure to complete the cut on the workpiece causes most uncontrolled stops (ramp-down errors).

Operation
- CNC controls and display
  A Computer Numerical Control (CNC) controls cutting system operation.
- Wireless device controls
  You can use a wireless device to set up and monitor the plasma cutting system.
- Power-indicator LEDs
  An Light Emitting Diode (LED) illuminates to show the power status on the plasma power supply and on other system components.
- Sequence of operation
  A set of flowchart images shows the sequence of operation for the plasma cutting system.
- Process selection
  All of the cutting processes have a process ID that is a unique identification number. Each process ID aligns with a set of preprogrammed values in the cut chart database in the plasma power supply control Printed Circuit Board (PCB).
- Cut charts
  A cut chart contains parameters that are necessary to get optimal results for your cutting process with special materials and thicknesses.
- Torch consumables
  The plasma cutting system uses the same consumable parts for perpendicular-position processes (90° angle) and bevel-cutting processes.
- Example configurations for consumables
  Consumables that are worn or have damage can have a bad effect on cut quality.
- Recommendations for maximum consumable life
  Consumables are the parts of the torch that wear as they are used. Consumables that are near end-of-life can have a bad effect on cut quality and performance.
- Arc Response Technology
  Arc Response Technology™ lets the plasma cutting system adapt to problems at the torch that can cause decreased consumable life or possible torch damage.
  - Automatic torch protection
    When consumables have a catastrophic failure (or blow out) at high-current settings, torch damage is possible. This torch damage can occur from the plasma arc or from molten copper or brass that gets into the coolant paths of the torch.
  - Automatic ramp-down error protection
    For LongLife® technology, a controlled stop of the current and gas pressure is necessary for protection of electrode life for mild steel cut processes. A failure to complete the cut on the workpiece causes most uncontrolled stops (ramp-down errors).

Automatic ramp-down error protection

For LongLife® technology, a controlled stop of the current and gas pressure is necessary for protection of electrode life for mild steel cut processes. A failure to complete the cut on the workpiece causes most uncontrolled stops (ramp-down errors).

Failure to complete the cut on the workpiece causes the plasma arc to extend too far and then to snap out (break) in a ramp-down error, which can quickly decrease consumable life. These are common causes for a ramp-down error:

Incorrect hole lead outs
Cutting off the edge of the workpiece

The cutting system can sense a ramp-down error before the arc snaps out (breaks) and can adjust quickly to do a controlled stop of the current and gas pressure. This type of controlled stop can help very much to increase electrode life, especially when cut speeds are less than 3,560 mm/min (140 in/min).
