6.4.2 Synergy control mode
In synergy control mode, the operator first has to preselect material/gas [19] and
wire diameter [20].
While changing the voltage (with the voltage selectors [2,3]) digital instrument [14]
and lamps [17,18] on the front panel show welding parameters.
Synergy status lamp [17] is green (only in synergy mode) when correct welding
parameters are set, or red when incorrect or not allowed welding parameters are set
(then machine operation is disabled!).
Note: Lamp is also red (in all control modes):
S if during welding (gun trigger pressed) – any voltage selector [2, 3]
is operated, then the operation of the machine is disabled immediately until
the trigger is released,
S when the gun trigger is pressed while turning on the machine with switch [1].
One of the lamps [18] points at recommended current outlet (–) with appropriate
inductance [9,10,11].
Digital display [14] shows values depending on display selectors [15, 16]
and machine status.
Before welding start: the upper display shows expected values of welding current [A]
or voltage [V] (both only in SYNERGY mode); the lower display shows wire speed
reference [m/min] or recommended maximum thickness [mm] of workpiece.
During welding: upper display shows actual welding voltage or current, the lower
display – as above.
After welding stop: the upper display shows last memorised (HOLD) values of
voltage or current (dimmed display).
Wire speed is set by program (stored in the microprocessor) and the knob [12] shall
be set to middle position ”0”. If necessary the operator may correct the preset speed
reference with that knob within +/– 20% of the set value.
The ESABMig C420s/C420sw include program for two types of cored wires,
designed for welding with positive polarity:
S OK Tubrod 1514 – φ 1,2mm
S OK Tubrod 1413 – φ 1,2mm
To select those wires set synergy switch [19] to position FCW – Ar2CO
2
and set
knob [20] to 1,6mm for ESAB Tubrod 1514 or to 1,2mm for OK Tubrod 1413.
