WARNING
MACHINE MOTION CAN CAUSE INJURY
The end-use customer and the cutting machine supplier are responsible for
providing protection against the hazardous moving parts of this cutting system.
Read and follow the instruction manual provided by the cutting machine
supplier. Refer to the Safety and Compliance Manual (80669C) for more safety
information.
Before you begin: Before you remove the power from the cutting system, it can be helpful to move the
torch to the edge of the cutting table and raise the torch lifter to its highest point. This provides easier
access to the torch and consumable parts.
1. Set the line-disconnect switch to the OFF position.
2. If the cutting system is not hard wired, disconnect the main power from the electric power.
If the cutting system is hard wired, you cannot disconnect the main power from the electric power.
Even if you remove the power from the cutting system, you can still get a serious electric shock if the
plasma power supply remains connected to an electric power source. Use extreme care during service
and maintenance when the cutting system is connected to electricity.
3. Make sure that the power-indicator LED is not illuminated on the plasma power supply, gas connect
console, or torch connect console.
Examine the gas regulators
Before you start cutting system operation, examine the regulator (or regulators) for the supply gases.
1. Examine the regulator (or regulators) for the supply gases before you start the cutting operation.
2. Be sure the supply gas pressures and flow rates are within the recommended range.
Refer to Process-gas requirements for all gas connect consoles on page 48.
3. Adjust the regulator (or regulators) accordingly.
Examine the shield water regulator (if applicable)
If your cutting system uses water as a shield fluid, examine the shield water settings before you start
cutting system operation.
1. Make sure that the water pressure and flow rate is within the recommended range.
