Clean and Inspect

As part of the proper maintenance of plasma cutting machines, you need to carry out routine cleaning and inspections, as don’t forget, this tool comes into close contact with molten metal on a daily basis!

There are several steps within these processes which are as follows:

  • Inspect the air filters to check for moisture, oil and particulates and vacuum any away gently. If you find that you often need to replace your air filters, you may have an issue with the quality of your compressed air.
  • Check the coolant level. If it is below the neck of the tank, you need to add more. If it appears dirty, you should flush it out and replace it with fresh coolant.
  • Inspect your plasma torch. You need to check over both the O-ring and the coolant tube, as well as clean them.
  • Check for gas leaks. Conduct the built-in leak and flow tests on a weekly basis.
  • Inspect the plasma arc. The pilot arc relay should be inspected for excessive pitting and replaced if needed.

Check common wear items

As well as routine maintenance tasks, you also need to check your plasma consumables, i.e., the components of your plasma cutter that have a certain life cycle and will need replacing at some point.

The frequency at which you need to replace a specific part of the machine, such as your torch consumables, main contactors and relays, will be dependent on how often you use your machine. However, typically, each item will need replacing after a set number of months or arc hours.

Recommendations are as follows:

Every six months or 500 arc hours, you should replace:

  • Torch O-rings and bullet plugs
  • The air filter
  • The coolant filter

Every 12 months or 1,000 arc hours, you should replace:

  • The torch main body
  • The pilot arc relay
  • The main contactor

Every two years or 2,000 arc hours, you should replace:

  • The torch receptacle
  • The coolant pump
  • The torch leads
