Hypertherm 005112 Pressure Switch

Overview

The Hypertherm 005112 pressure switch is a safety device that monitors the air pressure in a plasma cutting system. If the air pressure drops below a safe level, the pressure switch will shut off the plasma cutter to prevent damage to the equipment.

Specifications

• Brand: Hypertherm
• Part number: 005112
• Part description: pressure switch
• Pressure range: 0-150 PSI

Installation

The Hypertherm 005112 pressure switch is typically installed in the air supply line to the plasma cutter. The switch should be mounted in a vertical position with the arrow pointing in the direction of air flow.

Wiring

The Hypertherm 005112 pressure switch has two terminals: a normally open (NO) terminal and a normally closed (NC) terminal. The NO terminal is connected to the positive terminal of the plasma cutter's power supply, and the NC terminal is connected to the negative terminal.

Troubleshooting

If the plasma cutter is not starting, the pressure switch may be the cause. To troubleshoot the pressure switch, follow these steps:

1. Check the air pressure in the system. The pressure should be within the range specified in the switch's specifications.
2. Check the wiring connections to the pressure switch. Make sure that the wires are connected to the correct terminals.
3. If the air pressure and wiring connections are correct, the pressure switch may be faulty. Replace the pressure switch with a new one.

Conclusion

The Hypertherm 005112 pressure switch is an important safety device that helps to protect the plasma cutter from damage. By following the installation and troubleshooting instructions in this document, you can ensure that the pressure switch is functioning properly.
