5.2 Functions explanation
5.2.1 Overheating protection
When the machine is switched on with the mains switch [1], indicating lamp [1] is on and
lamp [2] off -- the machine is ready to operate. If the internal temperature becomes too
high, the welding is interrupted and disabled. This state is indicated by lighting of the
orange indicating lamp [2] on the front of the machine. It resets automatically when the
temperature has fallen.
