3-13 INSTALLATION, OPERATION AND SETUP
17. Intelligent Fan Control
The Fabricator 181i is designed with an intelligent fan control. It automatically switches the cooling fan off when
it is not required. This has two main advantages; (1) to minimize power consumption, and (2) to minimize the
amount of contaminants such as dust that are drawn into the Power Source.
Note that the fan will only operate when required for cooling purposes and will automatically switch off when
not required.
Note in STICK mode the fan operates continuously.
18. Local / Remote Switch (located in wirefeed compartment)
The remote / local switch is used only when a remote control device (such as a TIG Torch with remote current
control) is fitted to the Power Source via the remote control socket (Control No. 8). When the local/remote
switch is in the remote position, the Power Source will detect a remote device and work accordingly. When in
the local mode, the Power Source will not detect the remote device and will operate from the Power Source
controls only. Note that the trigger will operate at all times on the remote control socket irrespective of the
position of the local remote switch (ie in both local and remote modes).
Should a remote device be connected and the remote/local switch set to remote, the maximum setting of
the Power Source will be determined by the respective front panel control, irrespective of the remote control
device setting. As an example, if the output current on the Power Source front panel is set to 50% and the
remote control device is set to 100%, the maximum achievable output from the Power Source will be 50%.
Should 100% output be required, the respective front panel control must be set to 100%, in which case the
remote device will then be able to control between 0-100% output.
19. Burnback Control (located in wirefeed compartment)
The Burnback control is used to adjust the amount of MIG wire that protrudes from the MIG Gun after the
completion of MIG welding (commonly referred to as stick-out). To decrease the Burnback time (or lengthen
the amount of wire protruding from the MIG Gun at the completing of welding), turn the Burnback control
knob counterclockwise . To increase the Burnback time (or shorten the amount of wire protruding from the
MIG Gun at the completing of welding), turn the Burnback Control knob clockwise.
20. MIG Gun & Spool Gun Switch
The MIG Gun / Spool Gun switch is used to switch welding mode between MIG Gun functionality and Spool
Gun functionality
21. 10A Fuse
The 10A fuse is used to protect the spool gun motor.
