4-2. Switching On the Unit and Recalling Factory Parameters
. Write down any parameters
that need to be restored before
performing this procedure.
1 Power Switch
Use power switch to turn unit On.
When ITW appears on D1 and D2,
press P3 and P8 simultaneously.
When MEMO CLEAR appears on
D1 and D2, release P3 and P8.
Wait until DONE appears on D1,
and turn unit Off.
The next time unit is turned On, all
parameters will return factory de-
fault settings.

Press P3 until desired process LED illumi-
nates.
Values and parameters that appear on D1
and D2 are either factory default settings or
last settings entered for the selected pro-
cess.
L1 selection is Manual MIG welding.
D1 value is welding voltage, default is
18.5V (range is 10 V to 50 V).
D2 value is wire feed speed, default is 5.0
m/min (range is 1 m/min to 20 m/min). See
Section 4-10.
L2 selection is Synergic MIG welding (non-
pulsed).
D1 value is trim, default is 0.0 T (range is
−5.0 T to 5.0 T).
D2 value is wire feed speed (from minimum
to maximum value according to welding
curve selection).
. When L2 is flashing, material transfer
in the arc is by large droplets (globular
transfer) and produces considerable
spatter. This is the result of selecting a
specific material, wire, gas, voltage,
and current combination. To avoid this
situation, Synergic Pulsed MIG weld-
ing with the same parameter combina-
tion is recommended. When L2 is On
continuously (not flashing), material
transfer in the arc is either short circuit
(Short Arc) or by small droplets (Spray
Transfer). Both MIG processes pro-
vide a stable arc and minimum spatter.
L3 selection is Synergic Pulsed MIG weld-
ing.
D1 value is trim, default is 0.0 T (range is
−5.0 T to 5.0 T).
D2 value is wire feed speed (from minimum
to maximum value according to welding
curve selection).
L4 selection is TIG welding or STICK weld-
ing.
If selected process is TIG:
D1 displays TIG, and D2 value is welding
current, default is 220 A (range is 10 A to
400 A).
If selected process is STICK:
D1 initially displays STICK and changes to
open circuit voltage at approximately 85 V,
and D2 value is welding current, default is
220 A (range is 10 A to 400 A).
