switch (20), the display will alternate between "SPE" (to indicate spool gun external) and
the selected wire speed which is adjusted with a potentiometer located on the spool gun
handle.
c. In MIG, "GMAW" Synergic Mode (2T/4T), the display shows the selected wire speed
from 1 (minimum wire feeder speed) to 80 (maximum speed). If Remote is selected with
switch (20), the display will alternate between "SPE" (to indicate spool gun external) and
the selected wire speed which is adjusted with a potentiometer located on the spool gun
handle.
5. RIGHT DISPLAY: During welding it displays the actual arc voltage. When the machine is
not welding (no load) it displays the value of the parameter adjusted with the Right Knob (7):
a. In STICK, "SMAW"Mode it displays the Hot Start over-current value expressed as a
percentage of the base welding current selected with the left knob (8). The over current
value is variable from 0 to 50% of the base current. Maximum Hot start value of 50%
can be adjusted up to 55 Amp of welding current. On the display the value of Hot Start
is shown as "H" and the value of the over current in %.
b. In TIG, "GTAW" Mode the display is not active.
c. In MIG, "GMAW" Manual Mode (2T/4T) it displays the selected arc voltage from
10V to 24V.
d. In MIG, "GMAW" Synergic Mode (2T/4T) it displays the value of the selected voltage
expressed as a percentage of the maximum available voltage.
6. SELECTOR SWITCH FOR THE WELDING MODES SELECTION: STICK, "SMAW" -
TIG, "GTAW" - MIG, "GMAW" manual 2T, manual 4T, Syn 2T, Syn 4T.
7. RIGHT KNOB: It is used to adjust the following welding parameters:
a. In STICK, "SMAW"Mode it adjusts the over-current value of the electric arc (Hot Start),
variable from 0 to 50% on the current value adjusted with the Left Knob (8).
b. In TIG, "GTAW" Mode is not active.
c. In MIG, "GMAW" Manual Mode (2T/4T) it adjusts arc voltage value (no load) from
10V to 24V.
d. In MIG, "GMAW" Synergic Mode (2T/4T) it adjusts the % of welding power available
(depending on the input voltage) variable from 0 to 80% (maximum power).
8. LEFT KNOB: It is used to adjust the following welding parameters:
a. In STICK, "SMAW"Mode it adjusts the current value from a minimum of 20Amp to a
maximum of 80 Amp. If Remote is selected with switch (20) the left knob is not active.
b. In TIG, "GTAW" Mode, it adjusts the current value from a minimum of 5 Amp to a
maximum of 100Amp. If Remote is selected with switch (20) the Left knob is not active.
c. In MIG, "GMAW" Manual Mode (2T/4T) it adjusts the wire speed from 1 (minimum wire
feeder speed) to 80 (maximum speed). If Remote is selected with switch (20) the Left knob
is not active.
d. In MIG, "GMAW" Synergic Mode (2T/4T) it adjusts the wire speed from 1 (minimum
wire feeder speed) to 80 (maximum speed). If Remote is selected with switch (20) the Left
knob is not active.
9. NEGATIVE DINSE SOCKET:
a. In STICK Welding, "SMAW" for the connection of the ground cable connector (check
for correct polarity for the electrode you are going to use, refer to the information on its
box);
b. In TIG Welding, "GTAW" for the TIG torch cable connection (Torch trigger connection
must be connected to the 7 pin connector – 12 -)
c. In MIG Welding, "GMAW" (with gas) for the connection of the ground cable connector
10. POSITIVE DINSE SOCKET:
a. In STICK Welding, "SMAW", for the connection of the ground cable connector (check
for correct polarity for the electrode you are going to use, refer to the information on its
box);
