If no mains connection is available, you can use FastMig X 350 and X 450 on a generator. The minimum recommended generator output is 35 kVA. The greater the output, the more stable is the FastMig X power source operation.
On my FastMig X machine, what is the normal cooling fan sequence, start up and in operation?
FastMig X power sources incorporate two simultaneously operating fans.
The fan is started momentarily when the main switch is turned into position I.
The fan will start during welding as the machine reaches operational temperature, and it will continue running for 1 to 10 minutes after the welding has stopped, depending on the welding cycle completed.
The factory default setting for FastMig X 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 Config 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 Config 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/off 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.
