Examine the coolant condition and level

Examine the coolant condition and level in the plasma cutting system. Replace the coolant if you find copper pieces or debris or if the coolant is clear and not the original pink color. Add coolant if the level is low.

  • For the XPR170® and XPR300®, the location of the coolant reservoir is in the plasma power supply.
  • For the XPR460®, the location of the coolant reservoir is in the cooler.
  1. Remove the cap from the reservoir inlet found on top of the reservoir.
  2. Examine the reservoir internally for coolant contamination. OptionDescription
    If you find any contamination Replace all of the coolant.
    Note:

    Refer to Remove old coolant from the plasma cutting system.
    If you do not find contamination Continue to the next step.
  3. If the coolant level is low, add coolant (028872) until the coolant is at the recommended fill level.
    • For the XPR170 and XPR300, if the coolant is below the base of the inlet spout, add coolant to the reservoir until the coolant is at the base of the inlet spout.This image shows an example reservoir inleton a plasma power supply.
    • For the XPR460, if the coolant is below the maximum fill line on the coolant-level view window on the cooler, add coolant to the reservoir until the coolant level is at the maximum fill line.
      This image shows the view window and maximum fill level on the front of the cooler.

  4. Install the cap on the coolant reservoir.
