OPERATING MANUAL
19.
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 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 (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 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.
20.
Burnback Control (located in wirefeed compartment)
The burnback control is used to adjust the amount of MIG wire that protrudes from the MIG torch 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 torch at the completing of welding), turn the
burnback control knob anti 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.
21.
Local / Spool Gun Switch (located in wirefeed compartment)
The Local / Spool Gun switch is used only when a Spool Gun is fitted to the unit via the remote control
socket (item 9). When the Local/Spool Gun switch is in the Spool Gun position, the unit will control the
wire drive motor in a Spool Gun. When in the local mode, the internal Wire Drive Unit is active.
Note that the trigger will operate at all times on the remote control socket irrespective of the position of
the Local / Spool Gun switch (ie in both local and Spool Gun modes).
22.
Cooling Fan
The Transmig 220i is fitted with a fan as needed feature. Fan as needed automatically switches
the cooling fan off when it is not required. This has two main advantages; (1) to minimize power
consumption, and (2) to minimise 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.
23.
Hot Start Feature (Not Shown)
This feature operates in Stick (Manual Arc) mode. The Hot Start feature improves the arc start
characteristics by momentarily increasing the welding current to a level above the preset amperage
(Welding Current). This is a preset feature and is not adjustable.
24.
Anti Stick Feature (Not Shown)
This feature operates in Stick (Manual Arc) mode. The anti stick feature senses when the electrode sticks
and automatically reduces the current to prevent the Stick Electrode from sticking to the work piece. This
is a preset feature and is not adjustable.
