TROUBLESHOOTING - PLASMA CUTTING PROBLEMS
The proper installation, application and operation of plasma arc cutting equipment can save many man
hours and reduce costs which will give you the promised cut quality and longer consumable parts life.
Cut quality issues or poor consumable life are generally the most experienced problems seen with plasma
cutting systems and more often than not are caused by the same thing, for example, low or too high air
pressure, low air flow, water or oil in the supply airline will all give you poor cut quality and premature
consumable wear. It
’ s often difficult to diagnose cutting issues without understanding the machines use
and setup and there are various questions that need to be asked to be able to give the best advice.
Below is listed a few pointers to help you on your way to obtaining consistently good cut quality:
• Ensure your mains power supply is suited to the plasma cutting machines specifications.
• Ensure the supplied gases or air supply is in keeping with the requirements of the plasma machine.
• Ensure your plasma machines amperage setting matches the amperage of the cutting tips.
• Clean and service the plasma machine and torch regularly, it is important that the operator watch the
torch for signs of contamination or worn consumables being used.
