1 Control panel,
see separate instruction manual
2 Connection CAN for remote control unit
3 Connection for start signal from the
welding torch

Fan control

The power source has a time control that means that the fans continue to run for 6.5
minutes after welding has stopped, and the unit switches to energy-saving mode. The fans
start again when welding restarts.
The fans run at reduced speed for welding currents up to 110 A, and at full speed for higher
currents.

Overheating protection

The welding power source has overheating protection that operates if the temperature
becomes too high. When this occurs the welding current is interrupted and a fault code is
displayed on the control panel.
The overheating protection resets automatically when the temperature has fallen.
