3. OPERATION CONTROL
3.1 Main switch I/O
When you turn the on/off switch into I -position, the pilot warning lamp is illuminated and
the machine is ready for use. Always turn the machine on and off with the power source mains
switch. Never use the mains plugs as a switch.
3.2 Pilot lamps
The pilot lamps of the machine report its operational state:
The green pilot lamp when lit, indicates that the machine is switched on and ready for
use, and that it is connected to the mains supply with the power source main switch in the
I-position.
When lit, the orange lamp indicates that the thermal protection circuit has been activated due
to higher than normal working loads that exceed the rated duty cycle. The cooling fan will
continue to run and cool the machine down. When the lamp is off the machine is again ready
to weld.
3.3 Operation of cooling fan
FastMig Pulse power sources incorporate two simultaneously operating fans.
• The fan is started momentarily when the main switch is placed into position - I.
• The fan will start during welding as the machine reaches operational temperature, and
it will run for 1 to 10 minutes after the welding has stopped, depending on the welding
cycle completed.
3.4 Manual Metal Arc Welding
FastMig Pulse power source can be used for MMA electrode welding by connecting the
FastMig MXF wire feeding unit and PF function panel. MMA function is optional in FastMig
Pulse equipment, and therefore can be activated by purchasing the appropriate licence for the
MMA process. Please see ordering number codes. FastMig Pulse power source will not support
the MMA process without an MXF wire feeder connected.
