Changing the Water Tube
Problems and causes you may find with a defective or improperly installed water tube:
• Short electrode life: The water tube is not screwed in tightly.
• Flow switch interlock shutting down the system: Water flow is restricted due to a loose water tube.
• Humming or rattling sound coming from the torch: The water tube is bent or loose.
If you suspect a problem with the water tube, you may need to replace it.
1. Disconnect the power supply from the power source.
2. Remove all consumables from the torch (see Changing Consumable Parts ).
3. Look for any damage or bends in the water tube.
4. Remove and replace the water tube by using the water tube wrench supplied by Hypertherm –
