ADVANCEMIG400C
In Depth Controls Explanation
7a - MIG Synergic function makes the setup of MIG
welding more simple; the operator sets the welding
parameters; welding material, welding wire size, gas
type, material thickness and the machine
automatically calculates the optimal voltage and
wire speed required. When in synergic mode, the
welding power can be adjusted by either wire
feeding speed (20a), material thickness (20b), or
welding current (20c). Adjusting one of these
parameters will adjust the others together.
The intelligent synergic program will only allow a
selection or range of parameters according to
recommended best practise to obtain optimum
welding results. If the parameter or output required
is not available, this means the operator may need
to change to a different wire size or other primary
setup input required for the job.
Other variables such as welding joint type and air
temperature may affect the optimal voltage and
wire feed setting required, so the synergic program
provides a voltage fine tuning function for the
synergic program selected (15c). Once the voltage
is adjusted in a synergic program, it will stay fixed at
this variation as the material thickness/ wire speed/
current setting is changed. To reset the voltage for
a synergic program back to factory default, change
to another program and back again, or manually
adjust the voltage +// back to 0.
7b - MIG Manual Mode - Voltage and wire feeding
speed settings are controlled independently, like
traditional non synergic mig welding machine
controls.
8a. 2T Trigger mode - the trigger is pulled and held
on to activate the welding cycle, when the trigger is
released, the welding cycle finishes.
8b. 4T is known as 'latching' mode. The trigger
is pulled once and released to activate the welding
circuit, pulled and released again to stops the
welding circuit. This function is useful to longer
welds as the trigger is not required to be held on
continuously, reducing operator fatigue.
8c 4T Multi Level Trigger Mode - Pull and hold
the trigger to activate start current level set. Release
trigger to activate main welding current. Pull and
hold trigger again to activate finish current level set.
Release trigger to finish welding and activate post
gas.
8d Spot Welding Mode - Welding arc will start and stop
automatically according to the spot time set.
15b - MIG Wave Control/ Inductance Setting -
This setting changes the MIG waveform to simulate
changing the inductance of the welding circuit.
Inductance controls the rate of the current rise and fall
as the welding wire contacts the workpiece (known as
a short circuit). More inductance increases the short
circuit time and decreases the short circuit frequency
rate. This causes a wider and more penetrating arc,
useful for thicker weld joints. Less inductance will
create a narrow more focused arc. This effect can also
be used to fine tune the arc to produce less splatter.
Wire speed, wire size and type, shielding gas will all
change the effect that the inductance setting has on
the welding arc. Inductance change will have little
effect on MIG spray transfer process (as opposed to
short circuit process).
17 Alarm/Over Temp Indicator Lamp - Lights when
over voltage, current or temperature is detected and
protection is activated. When activated, welding output
will be disabled until the overload condition has
reduced sufficiently and indicator lamp goes out.
– Refer duty cycle rating. If this indicator light stays
illuminated permanently, this may indicate internal
machine damage, in which case please contact Strata
customer service.
Duty Cycle Rating - Welding duty cycle is the
percentage of actual welding time that can occur in a
ten minute cycle. E.g. 20% at 160 amps - this means the
welder can weld at 160 amps for 2 minutes and then
the unit will need to be rested for 8 minutes. All duty c
ycle ratings are based on an ambient air temperature
f 40°C with 50% humidity, which is the international
standard for such a rating. In an environment with
temperatures exceeding 40°C, the duty cycle will be
less than stated. In ambient temperature less than
40°C, duty cycle performance will be higher.
21,22,15a - Settings save/ recall function. This feature
can be used to quickly save and easily recall settings for
a specific job. To save a setting, press the save button
(22), rotate RH control knob to the desired program
spot (1-99 program setting spaces), press the save
button (22) again to save the settings. To recall a setting,
press the recall button(21), rotate the LH control knob
to select the program number required, press the recall
button again to load the program.
