ESAB FABRICATOR 141i
16. On / Off Switch
This switch is used to turn the Power Source on/off.
WARNING
When the front digital displays are lit, the machine is connected to the Mains supply voltage
and the internal electrical components are at Mains voltage potential.
17. Intelligent Fan Control
The Fabricator 141i 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 local/ remote 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 (8 Pin Remote Socket). 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 local/ remote 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 function and Spool Gun function.
21. 10A Fuse
The 10A fuse is used to protect both spool gun motor and internal motor.
