Selecting Synergic Mig Welding - Miller Electric XMS 44 Owner's Manual

4-11. Selecting Synergic MIG Welding

Set Synergic MIG welding process on the
power source. L7 is ON.
In Synergic MIG mode, the operator may
need to adjust welding data (wire type, wire
diameter, and gas type) and only one weld
parameter. Generally, wire feed speed is
adjusted and the synergic process auto-
matically sets appropriate weld voltage.
Synergic welding also sets many secon-
dary welding parameters automatically for
improved weld quality.
Trim parameter appears on D1 and D2:
D1 value is default trim setting of 0.0 T
(range is −5.0 T to 5.0 T).
D2 value is default wire feed speed setting
of 5.0 m/min (minimum (MIN), maximum
(MAX), or default (DEF) values are arbi-
trary based on set welding data). Use P2
and E2 to change this display to amperes
or to the thickness of the material.
While Setting Parameters:
- L2 ON means that D1 shows Trim value.
- L3 ON means that D2 shows the wire
speed in meter/min or inch/min.
- L4 ON means that D2 shows the set weld-
ing current in amperes.
- L5 ON means that D2 shows the thick-
ness of material to weld.
While Welding:
- D1 shows the measured welding voltage
in Volts. L1 is ON.
- D2 shows the measured welding current
in amperes. L4 is ON.
Set wire speed, welding current or material
thickness and welding voltage with E2 and
E1.
Select trigger mode using P1 pushbutton
(see Section 4-4).
If necessary, use P2 to adjust the welding
parameters.
Purge air from gun hose using P3 pushbut-
ton (see Section 4-8).

Setting Trim
D1 value is default trim setting of 0.0 T
(range is −5.0 T to 5.0 T).
Trim is an arbitrary value related to MIG arc
length. Higher values produce a longer and
hotter arc. Lower values produce a shorter
and cooler arc. Recommended value for
trim is default setting or near 0.0T. L2 is On.
Synergic MIG Welding Advanced Set-
tings
To change all values list, unit must be SET-
UP FULL. To set unit to SETUP FULL, pro-
ceed as follows:
Press P2 to enter SET UP menu.
Select SETUP FULL on D1 and D2 (see
Section 4-6).
Setting Main Welding Regulations
Enter SET UP and select rEG on D1 with
E1.
D2 shows the main parameter and E2
changes it.
When D2 shows SPE (wire speed) the
main regulation is the speed of the welding
wire. L3 is ON.
When D2 shows A (ampere) the main regu-
lation is the welding current in Amperes. L4
is ON.
When D2 shows thc (thickness) the main
regulation is the material thickness in mm.
L5 is ON.
.
The modification to the main welding
regulation is confirmed when exiting
the Set Up Menu.
.
The measured welding current can be
different from the set value. This differ-
ence can be greater if there are
changes on the default parameters
and if the welding conditions are not
conventional. Setting amperage must
be considered a reference.
.
Material thickness setting is a refer-
ence value only.

Setting Inductance
Press P2 to enter SET UP menu.
Use E1 to select on D1 ind. D2 shows 100.
If necessary, use E2 to adjust inductance
value (range is 1% to 200%).

Wire Feed Speed Unit (only in SETUP
FULL)
See Section 4-10.
Setting Pre−Gas (only in SETUP FULL)
See Section 4-10.
Setting Post-Gas (only in SETUP FULL)
See Section 4-10.
Setting Burnback (only in SETUP FULL)
See Section 4-10.
Setting Run-In (only in SETUP FULL)
See Section 4-10.
Setting 3 Level Trigger Mode (only in
SETUP FULL)
Use E1 to change D1 to 3L.1
D2 value is the default setting of 130%
(range is 20% to 200%).
Use E2 to change D2 value.
Use E1 to change D1 to 3L.2
D2 value is the default setting of 80%
(range is 20% to 200%).
Use E2 to change D2 value.
Use E1 to change D1 to 3L.r
D2 value is the default setting of 0.5 s
(range is 0.1 s to 0.5 s).
This value is the ramp time in seconds to
reach the following level wire speed.
Higher inductance setting produces a
softer weld puddle and less spatter, but
arc starts may be more difficult. Lower
inductance setting produces a stiffer
weld puddle and more spatter, but arc
starts may be easier.
