Fill the cutting system with coolant

Use the correct amount and type of coolant mixture to help prevent damage to the cutting system.

Notice

LOW COOLANT LEVELS CAN DAMAGE THE CUTTING SYSTEM AND COOLANT PUMP

There is a risk of serious damage to the cutting system and to the coolant pump if you operate the cutting system with no coolant or with low coolant. If your coolant pump is damaged, pump replacement can be necessary.

Never operate the cutting system if you get a low coolant level notice.

Notice

AUTOMOTIVE ANTIFREEZE CAN CAUSE DAMAGE TO THE TORCH COOLANT SYSTEM

Antifreeze contains chemicals that can cause damage to the torch coolant system.

Never use automotive antifreeze as an alternative to Hypertherm coolant.

Notice

USE THE CORRECT COOLANT

If you use an incorrect coolant, it can cause damage to the cutting system.

Refer to the coolant requirement specifications for your plasma cutting system.

Calculate the correct percentage of propylene glycol to add in the premixed Hypertherm® coolant (028872).
Refer to Coolant requirements.

Remove the power from the cutting system:
1. Set the line-disconnect switch to the OFF position.
2. Make sure that the power-indicator Light Emitting Diode (LED) on the plasma power supply is not illuminated.
Make sure that you have the correct coolant mixture for your cutting system.
Remove the cap from the reservoir inlet on top of the plasma power supply.

If the coolant is below the inlet, add the coolant in the reservoir until the coolant is at base of the inlet.

CAUTION

WET FLOOR

If you put too much coolant in the reservoir, the coolant can spill onto the floor. Coolant can cause floors to become slippery.

Be careful not to put too much coolant in the reservoir.

Install the cap onto the coolant reservoir.
Supply the power to the cutting system:
1. Set the line-disconnect switch to the ON position.
2. Make sure that the remote on-off switch is in the ON position.
3. Make sure that the green power-indicator LED is illuminated on the plasma power supply.
Use the Computer Numerical Control (CNC) or XPR® web interface to send a process to the plasma power supply and start the coolant pump.
- When you send a process, the gases start to flow, and after a few seconds the coolant pump starts.
- If the pump stops, it is necessary to purge the air out of the coolant loop.
- Use the remote on-off switch to start and stop the coolant pump until the pump continues to run.
If necessary, add more coolant to fill the reservoir to the base of the reservoir inlet.

After you add the coolant, use the CNC or XPR web interface to cancel the low-coolant diagnostic code or select a process.
