Wiredrive motor circuit breaker
The 4A circuit breaker protects the unit from electrical faults and will operate in the event of a
motor overload.
NOTE!
If a circuit breaker trips, a short cooling period must be allowed before an attempt
is made to reset the unit by pressing the circuit breaker reset button.
Local / remote switch (software control)
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 unit via the remote control socket (item 9). When the
local/ remote switch is in the remote position, the unit will detect a remote device and work
accordingly. When in the local mode, the unit 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 (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 unit 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.
Burnback control (software control)
The burnback control is used to prevent the MIG wire from stickling the weld pool and 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 counter-clockwise. To increase the burnback time (or shorten the amount of wire
protruding from the torch at the completing of welding), turn the burnback control knob
clockwise.
NOTE!
For burnback to work as designed - The MIG GUN must remain in position at the
end of the weld- Retracting the gun will prevent it from working as designed.
