FastMig X
The factory default setting for FastMig Pulse is AUTO. If a cooling unit is not connected and
the operator tries to establish air-cooled operation together with an air-cooled gun, Err 27
is displayed. To establish air-cooled operation, select cooler ‘OFF’. This is done in the ‘System
Cong Menu’ as follows: Press the Menu button on the X 37 power source panel. Move the
menu display arrow (via panel's left-hand up-down arrow keys) to select ‘System Cong Menu’
and then press the select button. Choose ‘Water Cooling:Auto’ and change via control knob to
setting ‘Water Cooling:OFF’, then press Back/Exit. Cooler will then be set to the ‘OFF’ state for
air-cooled operation. Reset power source via on/o switch and continue welding.
When selected, the operation of the cooling unit is automatic, starting when welding
commences. When welding stops the pump will continue operation for approx. 5 min, so
reducing the gun and the cooling liquid to ambient temperature.
After completing the preparations explained above, the device is ready for welding. Before
welding, read the operating instructions.
3. OPERATION
3.1 Cooler operation
See also 2.4.2. Main parts of cooling unit
The Cool X cooler operation is controlled by the microprocessor of the power supply. The
cooler pump starts to operate when the welding begins. After the welding has stopped, the
pump will operate 1 to 5 minutes longer depending on the welding time. During this time the
liquid will cool down to the ambient temperature and cools down the welding gun.
Check the tank liquid level regularly and add liquid, if necessary.
If the tanks coolant liquid level runs low, welding is stopped and an error code appears on the
FastMig panel. See trouble-shooting 4.3.
3.2 Overheat signal lamp
The overheat signal lamp is lighting when temperature control of the machine has detected
cooling water overheat. The ventilator cools down the machine and when the lamp goes out
welding can be started again.
3.3 Storage
The machine must be stored in a clean and dry room. Protect the machine from rain and keep
it away from direct sunshine in places where temperature exceeds +25° C. Check that there is
free space in front of and behind the machine for air circulation.
