5.1 WIRINg.
For the extensions and protection devices wiring follow
the directions of the instruction manual provided with the
cooling unit.
5.2 DESCRIPTION Of PROTECTION DEVICES .
5.2.1 Coolant pressure protection device.
This protection is achieved by means of a pressure switch,
inserted in the fluid delivery circuit, which controls a mi -
croswitch. If the pressure is insufficient, the display
D1
shows the wording h2O flashing.
5.2.2 fuse (T 2A/250V - Ø 5x20).
this fuse protects the motor pump, and is located in the
fuse holder AH on the rear panel of the welding machine
(Fig. 12).
5.3 START-UP.
Unscrew the cap AU and fill the tank (the equipment is
supplied with approximately one liter of fluid).
it is important to periodically check, through the slot AT ,
that the fluid remains at the “max” level.
6 CONTROL PANEL DESCRIPTION (Fig. 13-14)
the control panel consists of a
control area
(Fig. 13) and
a settings area (Fig. 14).
6.1 CONTROL PANEL (Fig. 13) .
Selection key T1
every pressure of the key selects the size, adjust-
able via the M1 knob. available sizes, displayed by
leds L1 , L2 and L3 , relate to the selected welding
process.
Led L1 Thickness
it indicates that the display D1 shows the thickness in
mm of the workpiece based on the current and wire
speed set. Active in synergic MIG/MAG welding process -
es.
Led L2 Wire speed
it indicates that the display
D1
shows the welding wire
speed in metres per minute. Active in all MIG/MAG weld -
ing processes
Led L3 Welding current
it indicates that the display D1 shows the welding cur -
rent in ampere.
Knob M1
the values selected through the key T1 are adjust-
ed according to the process type selected through
this knob.
Display D1
Shows the value of sizes selected by means of key T1 and
adjusted by means of knob M1 .
Selection key T2
every brief pressure of the key selects the size,
adjustable via the M2 knob . the sizes that can be
selected, displayed by leds
L4
,
L5
and
L6
, are re-
lated to the selected welding process.
Led L4 Welding voltage
It indicates that the value shown on display D2 is a
value expressed in volts.
With arc off, in MIG/MAG welding processes, the value
shown on display D2 is a pre-set value or the “set point”
(see paragraph 9.1 MIG/MAG welding.).
During the welding process, the value shown on display
D2 is always the voltage measured by the power source.
Led L5 Arc length
In synergic MIG/MAG welding processes (MIG HD ex -
cepted), it indicates that display
D2
shows the value of
the lenght of welding arc correction.
the 0 (zero) value corresponds to the manufacturer preset
arc length.
By means of knob
M2
it is possible to increase the arc
(positive values) or reduce it (negative values) in a -9.9 ÷
+9.9. range
Led L6 Impedance
In MIG/MAG welding processes, it indicates that dis -
play D2 shows the impedance value.
the 0 (zero) value corresponds to the manufacturer preset
impedance.
