INSTALLATION, OPERATION AND SETUP 3-6 Manual 0-5205
5. Inch Button
The INCH button is active in 10 PIN GMAW/FCAW mode (MIG) only.
Press and hold the INCH button to inch the wire in the Wirefeeder (Active in 10 Pin mode only).
6. Local / Remote Button
The REMOTE button is used to select REMOTE or LOCAL mode of operation.
The REMOTE button is used only when a remote control device (such as a TIG torch with remote current
control, or a Wirefeeder) is fitted to the unit via the remote control socket (items 5 & 6). When the REMOTE
button 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.
7. 10 PIN / 19 PIN Remote Button
The REMOTE button is used to select 10 PIN, 19 PIN, mode of operation when the REMOTE button ( item
13) is in REMOTE mode.
When in 10 PIN Remote mode, the 10 PIN control socket is active and remote voltage or current / wire-
speed controls will be active.
The 10 PIN Remote mode is only available in GMAW/FCAW (Mig) and GTAW (Lift Tig) modes only.
When in 19 PIN Remote mode, the 19 PIN control socket is active and remote voltage controls will be active.
The 19 PIN Remote mode is only available in GMAW/FCAW (Mig) mode only.
NOTE
When operating a 10 pin Wirefeeder in remote mode, the maximum output is determined by the
settings of the power source (in local mode). This is done such that the maximum output available
at the wirefeeder can be restricted to a preset level. This preset level must be selected whilst the
machine is in local mode.
As an example, should 0-100% output control be required at the wirefeeder, the power source should
be set to local mode, and both the amps (wirespeed) and volts controls set to 100% (maximum). the
wirefeeder will then be able to control between 0-100% of output [both amps(wire speed) and volts].
Should 50% output be required at the wirefeeder controls, the power source should be set to local
mode, and both the amps (wirespeed) and volts set to 50% (mid point). The wirefeeder will then
be able to control between 0-50% of output [both amps(wirespeed and volts)]
NOTE
When a 19 pin wirefeeder in used, 100% output for both amps (wirespeed) and volts is available
at the wirefeeder at all times regardless of the amps (wirespeed) and volts control settings at the
power source (The power source display will show a series of dashes when in 19 pin remote mode).
The wirefeeder can adjust both amps (wirespeed) and volts between 0-100%.
NOTE
Welding Setup Program Storage (10 programs) applies to Mig 10 pin only, Stick and Lift Tig modes.
