9.3 Fan control
The power source fans continue to run for 6.5 minutes after welding has stopped,
and the unit switches to energy-saving mode. They start again when welding
restarts.
The fans run at reduced speed for welding currents up to 180 A, and at full speed for
higher currents.
9.4 Overheating protection
The power source has three thermal overload trips which operate if the internal
temperature becomes too high, interrupting the welding current and lighting the
orange indicating lamp on the front of the unit. They reset automatically when the
temperature has fallen.
9.5 Remote control unit
The program version in U8 should be 1.20 or higher. Machines with intergral control
panels should have program version 1.21 or higher, in order for the remote control to
function correctly.
When the remote control unit is connected, the power source and wire feed unit are
in remote control mode; the buttons and knobs are blocked. The functions can only
be adjusted via the remote unit.
If the remote control unit is not to be used, the remote control unit must be
disconnected from the power source / wire feed unit, as otherwise it will remain in
remote control mode.
For more information about the operation of the remote control unit, see the
operating instructions for the control panel.
10 MAINTENANCE

Only those persons who have appropriate electrical knowledge (authorized
personnel) may remove the safety plates.
Supplier warranty is void if customer attempts any work on product during the
