Condition of the consumable parts

If you use consumable parts that have damage, the consumable parts can melt. Copper pieces can break off and go into the coolant and cause these problems:
  • Decreased coolant flow
  • Increased coolant-flow errors
  • Damage to the other consumable parts
  • Coolant leaks at the check valve when you change consumable parts
  • Inaccurate coolant-flow indications
  • Decreased life of the coolant pump
  • Decreased life of the check valve

When you do maintenance, examine the coolant filter for copper pieces. If you find copper pieces in the coolant filter, replace the filter and all of the coolant. If coolant-flow errors occur after the filter and coolant are replaced, use the troubleshooting procedure in the instruction manual that came with your cutting system.

The best solution is to obey the usage recommendations for consumable parts. This reduces the risk for damage from too much use. If you use consumable parts more frequently than Hypertherm recommends, replace these components more frequently:
