Hypertherm 005243 Pressure Switch

Part Description

The Hypertherm 005243 pressure switch is a safety device used to monitor the air pressure in a plasma cutting system. The switch is located in the air line between the compressor and the plasma cutter. If the air pressure drops below a safe level, the switch will open and shut off the plasma cutter. This prevents the plasma cutter from operating without sufficient air pressure, which could damage the cutter or cause injury to the operator.

Specifications

• Pressure range: 0-150 PSI
• Maximum operating temperature: 150°F
• Electrical rating: 125VAC, 10A

Installation

The Hypertherm 005243 pressure switch can be installed in any orientation. The switch has a 1/4" NPT male thread on one end and a 1/4" NPT female thread on the other end. The switch should be installed in the air line between the compressor and the plasma cutter. The switch should be mounted in a location where it will not be damaged or bumped.

Wiring

The Hypertherm 005243 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. The NC terminal is connected to the negative terminal of the plasma cutter's power supply.

Troubleshooting

If the Hypertherm 005243 pressure switch is not working properly, the following troubleshooting steps can be performed:

• Check the air pressure in the air line. The air pressure should be within the switch's operating range.
• Check the electrical connections to the switch. The connections should be tight and secure.
• Check the switch for damage. If the switch is damaged, it should be replaced.

If the troubleshooting steps do not resolve the problem, the switch should be replaced.

Conclusion

The Hypertherm 005243 pressure switch is an important safety device that helps to protect the plasma cutter and the operator. The switch is easy to install and maintain, and it can help to prevent costly repairs and injuries.
