WARNING
Use extreme caution when working near live electrical circuits. Dangerous voltages are
inside the plasma power supply that can cause serious injury or death.
Live voltages can continue to be present on the DC bus for at least 30 seconds after
disconnecting the input power. Wait for bus voltages to be fully released before you do
any tests.
While testing, do not touch the nozzle at the end of the torch. Dangerous voltages can
cause serious injury.
