[12] has also an influence on the wire feeding
speed.
3. Thermal Overload Indicator: This lamp will light up
when the machine is overheated and the output has
been turned off. Leave the machine on to allow the
internal components to cool, when the lamp turns off
normal operation is possible.
4. Digital Display Panel:
•
Display A: It shows the actual welding current
value (in A), and after finishing welding
process, it shows the average value of the
welding current. When the WFS value is
changed [2], the display shows the value of
adjusted WFS (in m/min) - for manual mode or
correction of the speed automatically matched
by the machine, in the range 0.75-1.25 at
synergic mode.
•
Display V: It shows the actual value of welding
voltage (in V), and after finishing welding
process, it shows the average value of welding
voltage. When the WFS value is changed [2],
the display is blank.
•
Work Indicators: These lamps shows the work
mode of the machine:
When lit, the machine works in
SYNERGIC
Synergic mode (automatic mode).
When lit, the machine works in Manual
mode.
Select the desired work with the "Welding Material
and Gas Mix Choice Knob" [11].
5. Quick Connect Couplings (For water cooled model
only): For connecting water cooled torches.
Warm water from torch.
Cool water to torch.
6. Quick Connect Couplings (For water cooled model
only): If water cooled torches are used, connect
water lines from water cooler here. Refer to torch
and water cooler guidelines for recommended
cooling liquid and flow rates.
7. Fast-Mate Adapter: Input power connection.
8. Gas Connector: Connection for gas line.
9. Amphenol Connection: 8-Pin connection to power
source.
10. Wire Diameter Knob: It allows the choice of the wire
diameter requested for the desired welding process.
This feature is available only for the synergic mode.
11. Welding Material and Gas Mix Choice Knob: This
knob enables the choice of:
•
The welded material and its appropriate gas
mixture.
•
The manual / synergic work mode.
12. Wire Feed Slow Run Control Knob: It enables
control of wire feeding speed before welding
beginning, in the range from 0.1 to1.0 of the value
set by the "Wire Feed Speed Control Knob" [2].
13. Torch Mode Switch: It enables selection of 2-step
or 4-step torch mode. The functionality of 2T/4T
mode is shown in the picture below:

A. Welding Current.
B. Burnback time.
C. WFS.
G. Gas.
14. Burnback Time Control Knob: It enables to obtain
the desired length of electrode wire, which protrudes
from the tip of the torch after ending welding;
adjusting range from 8 to 250ms.
15. Cold Inch / Gas Purge Switch: This switch enables
wire feeding or gas flow without turning on output
voltage.
16. Spot Welding Time Control Knob: It enables time
control in the range from 0.2 to 10 s.
