6.3 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.
6.4 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.
6.5 TIG welding
TIG welding melts the metal of the workpiece, using an arc struck from a tungsten
electrode, which does not itself melt. The weld pool and the electrode are protected
by shielding gas.
