thickness.
Instead, the Synergic function auto-
matically defaults to a minimum Amp setting
based off of the combination of wire type and
wire diameter selected by the user.
Because of
the minimum factory default setting, this does
not necessarily create a ready
-
to
-
weld setting.
The user will have to select the correct amperage
for the thickness being welded. However, it does
create a useable
ratio
of voltage to Amps by link-
ing and locking (or rather electronically synchro-
nizing) them together, so that the Amp setting
alone can control both voltage and Amps (Wire
Speed) simultaneously. A rise in Amps will result
in a rise of Voltage. And of course, a decrease in
Amps will result in a decrease of Voltage.
Even
though the machine is in the Synergic mode and
designed to couple and control both Voltage
and Amps simultaneously through the Amp
setting, the Voltage can be fine
-
tuned at any
time by simply toggling to the Voltage adjust-
ment and manually readjusting the Voltage.
By
making a change in the Voltage manually, the
user can easily reprogram and establish a
new
ratio of Volts to Amps. Once Voltage has been
fine tuned manually by the user, the unit will
remember the new ratio of Volts to Amps. The
user will once again be able to use the Amp
setting to control both the Amps and Voltage
together through the Amp setting and the new
ratio will be retained until reset or the synergic
mode is exited. Note that If further fine tuning is
needed, the Voltage can be adjusted individually
at anytime without affecting a change in Amps.
As before, this new Volt/Amp ratio will be re-
membered as long as the welder is in the current
MIG synergic mode. Once the user has exited
the Synergic mode or the unit is powered down,
the user established ratio will be cleared from
memory and the unit will revert back to the fac-
tory set ratio. The user may notice that the
Amps displayed in digital display do not appear
to reflect much change, if any, while cycling be-
tween the different synergic wire types and wire
diameters.
This is normal.
Keep in mind that the
unit is programmed to default to a minimum
factory Amp setting for each change in the com-
bination of synergic input of diameter and wire
type. If the machine did display in
“
inches per
minute
”
instead of amps, a change would be ob-
served in the wire speed feed rate. The reason
that Amps are displayed instead of Inches Per
Minute (IPM) is as follows:
Due to the Ampacity
(the current carrying capability of a specific wire
because of its diameter and metal type) of differ-
ent available wires, each change of wire diameter
and type creates a different wire speed to main-
tain the same amperage.
In other words, while
welding, different wires that are feeding at the
same Inches Per Minute value will deliver different
Amp values.
Since the exact wire type and diame-
ter are known and input in the synergic mode, the
Amps can be accurately computed. In manual
mode, Amps are impossible to prefigure and only
wire feed rate can be displayed
.
Adjusting the Amp
value instead of the wire feed rate is a more accu-
rate and standardized way of welding a specified
thickness when varying wire thicknesses could be
used in the same application by different users.
It
should also be noted that while actively welding,
this unit reads actual output amps regardless of
manually adjusted or synergic modes.
To operate,
simply select the type and size of wire being used
once the synergic mode is selected.
Selectable
options for wire type include: Steel, Aluminum, and
Stainless. Wire sizes for the synergic function in-
clude,
.023”, .030”, .035”,
and
.045”
wire diame-
ters. Some exact wire sizes may vary from what is
listed. The synergic mode is not calibrated for Flux
-
Core or dual shielded wires, or every possible for-
mulation of filler wire, but does offer a good
starting ratio for most hard wires. Remember, the
synergic mode is designed to assist in setting up the
machine and greatly simplifies operation. Again, to
emphasize, the synergic mode will not automatical-
ly select the correct Amperage. It will only choose
the
best identified ratio
of Volts to Amps and is
dependent upon using industry standard shielding
gases for each metal. (ie 75/25 for steel, 98/2 for
Stainless, and 100% Ar for Aluminum). It is used in
lieu of complicated setup charts which can be inac-
curate and difficult to read. Use the Synergic setting
as a tool, and keep in mind that experience is the
ultimate resource for proper machine setup.
Spe-
cial Note concerning Synergic operation with the
spool gun: Make sure if you purchase a spool gun
for operation with this unit, that a MTS version of
the spool gun is purchased. This will offer you ex-
cellent control of both Amps and Volts through the
speed control knob located on the spool gun. This
is something particularly useful and will allow you
better control than any other brand or type of
spool gun on the current market by reducing your
need to visit the panel to make corrections to volt-
