The system changes the output current (A) or the operating mode after you set them

You selected the system setting while the torch was locked

The system does not keep changes to the output current (A) or operating mode while the torch-lock switch is in the yellow lock position or while there is an 0-50-n "Hypertherm® cartridge off" fault condition.

When you set the torch-lock switch to the green "ready to fire" position, the system automatically sets the amperage and operating mode to match the type of Hypertherm cartridge installed on the torch.

Note:

For more information on the 0-50-n fault condition, refer to Troubleshooting for torch-lock switch faults (0-50-n).

  • Set the torch-lock switch to the green "ready to fire" position before you adjust the amperage or operating mode.
