Weld data (13)
The weld data function is activated by pressing buttons 8 and 9 simultaneously. The weld data
function returns the welding current and voltage values to the displays that were in use when
welding was discontinued.
Selection of welding process (14)
The welding process selection button is used to select either normal MIG welding, in which wire
feed speed and welding voltage are adjusted separately, or Synergic 1-MIG welding, in which the
wire feed speed, welding voltage, and related parameters are optimally bound to each other. In
1-MIG welding, the setting for power and arc length (see '1-MIG welding') are adjusted.
Electrode welding (MMA) is selected by pressing the button for >1 second. N.B.! When electrode
welding is selected, the power source, the electrode holder connected to it and the MIG gun become
energised (idling voltage).
Settings selection button (10)
The settings selection button is used to choose the basic settings required. Active settings are
indicated by an LED pilot lamp. Settings are performed manually via the panel potentiometers or
remotely via the remote control unit linked to the unit's remote-control connector. If settings are
chosen to be performed via the gun controller connected to the welding gun, the wire feed speed /
setting for power (1-MIG) will be adjusted via the gun controller and the welding voltage/arc length
(1-MIG) adjusted via panel potentiometer No. 3.
N.B.! Remote control or gun settings can be chosen only if the controller in question is connected
to the equipment, and in gun control the SETUP parameter 'GUN' is position "ON".
Additional MIG functions (15)
The selection button for additional MIG functions can be used to activate the slow start ('Creep
Start'), hot start, or crater levelling ('Crater Level') function. Further presses of the selection button
can select one or more of the above functions. N.B.! Only the available additional functions for
each method can be selected.
Parameters related to these functions are set via the SETUP function (see 'SETUP functions').
The purpose of Creep Start is to facilitate the initial weld – e.g., when welding with a high wire
feed speed. The wire feed speed is kept low until the wire touches the work piece and the current
begins to flow. Creep Start can be selected with normal MIG welding or with Synergic 1-MIG
welding.
The purpose of the Hot Start function is to reduce initial welding errors when welding highly
heat-conductive materials such as aluminium. Hot Start can be selected when using Synergic
1-MIG welding and when the 4T operating mode is selected. In this case, when the start switch
of the gun is held down, a fixed pre-gas time is displayed after which welding starts at the level
determined by the SETUP mode's Hot Start parameter, returning to the normal level when the
gun switch is released.
Stopping is performed as with the normal 4T function.
The purpose of crater levelling is to reduce welding defects caused by end cratering. The Crater
Level function can be selected when using Synergic 1-MIG welding and when the 4T operating
mode is selected.
When the gun switch is pressed down in connection with termination of welding, the welding power
drops to the crater-filling level selected previously. The crater filling function is discontinued by
releasing the gun switch.
The values of parameters related to additional MIG functions can be changed either with the
SETUP function (see 'SETUP') or with the Quick SETUP function. Quick SETUP is activated
by simultaneously pressing buttons 15 and 6. In this way, parameters related to MIG additional
functions can be set.
Parameters are selected for adjustment either with button 15 or via potentiometer No. 2. The value of
the parameter is set via potentiometer No. 3. The value is immediately recorded in the memory.
