3.2. DESCRIPTION OF THE EQUIPMENT (pict. 1 and 2).
A - Negative output terminal (-)
B – ¼ gas fitting.
This is where the gas hose of the TIG welding torch is to be
connected.
C – 10-PIN CONNECTOR.
The following controls can be connected alternatively to this
connector:
- pedal control,
- torch with start button.
D - Positive output terminal (+)
E – Gas intake fitting.
F – Switch.
Turns the machine on and off.
G – Power supply cable.
H – Grill for air passage.
A1 – Selector switch for Test Gas
When the Test Gas is activated, the A2 LED lights.
A3 – Selector switch for high frequency ignition
This push-button selects the ignition type with high frequency or
by contact.
The A4 LED lights to display your choice.
A4 LED – Ignition with high frequency or by contact (only
TIG DC mode).
When the LED is off, to start the arc, press the torch trigger and
touch the tungsten electrode to the workpiece, then lift it. This
move must be quick and sharp.
When the LED is on, to start the arc, press the torch trigger: a
high voltage/frequency pilot spark will start the arc.
A5 - Selector switch Pulsed arc mode
When the LED A6 is on, the pulsed arc mode is activated.
Before starting the arc:
1. Set the two current levels.
First level: press the D1 knob until the D5 LED lights,
and adjust the main current using the D1 knob.
Second level: press the D1 knob until the D6 LED
lights, and adjust the current using the D1 knob.
2. Set the percentage of current on the two levels: press
the D1 knob until the E2 and C5 LEDs light and adjust
the percentage using the D1 knob.
3. Set the frequency of the period of the two levels: press
the D1 knob until the E3 and C6 LEDs light and adjust
the frequency using the D1 knob.
When the LED A6 is off, the continuous mode is activated.
B1 – 2-step and 4-step mode selector switch
In the welding procedure TIG, this push-button selects the 2-step
or 4-step mode.
The selection changes each time the button is pressed.
The B2 and B3 LEDs light next to the various symbols to display
the operated choice.
B2 LED – 2-step TIG welding (manual)
When the torch trigger is pressed, the current begins to increase
over the previously set "slope up" time (D4 LED on), until it
reaches the value set by means of the D1 knob. When the trigger
is released, the current begins to drop over the previously set
"slope down" time (D7 LED on), until it goes back to zero.
B3 LED – 4-step TIG welding (automatic)
This program differs from the previous one in that the arc is
both started and extinguished by pressing and releasing the
TIG torch
trigger.
B4 - TIG AC or TIG DC mode selector switch
B5 LED – AC TIG welding
B6 LED – DC TIG welding
B7 – MMA welding mode selector switch
Pressing this button the B10 LED will light.
This machine can weld with all types of coated electrodes,
except for cellulose ones. It can weld in AC mode (B5 LED
lit) or in DC mode (B6 LED lit).
The D1 knob adjusts the welding current.
Pressing the D1 knob, you can activate and adjust the Hot
Start (B9 LED) and the Arc Force (B8 LED) modes.
C1 – Display
Displays the welding current (C2 LED), the welding voltage
(C3 LED) and the settings which were selected and adjusted
via the D1 knob.
C2 LED – current value indicated on display C1
C3 LED – voltage value indicated on display C1
C7 LED – Thermal protection.
It lights when the operator exceeds the duty cycle.
N.B. Under this condition, the fan goes on cooling the
power source.
C8 LED – It lights when the switch F is in the ON position.
D1 – Knob.
Adjusts the welding current.
In addition, used as push-button/knob, it is possible:
- adjust the frequency,
- adjust the cleaning or the penetration,
- adjust the "slope up",
- adjust the pulse current,
- adjust the pulse frequency,
- adjust the "slope down",
- adjust the post gas,
- adjust the pre gas,
- adjust the starting current,
- adjust the end current.
D2 LED
Pre gas. Adjusts the gas flow time before welding (0,1-10
sec.).
D3 LED – Starting current
It is adjustable with the D1 knob:
- In DC: 5-100% of the welding current,
- In AC: 10-100% of the welding current.
D4 and C4 LEDs
Slope up. This is the time during which the current, starting
from the minimum, reaches the set current value (0-10 sec.)
D5 LED
Main welding current or first level current in pulsed arc mode.
D6 LED
Second level current in pulsed arc mode.
D7 and C4 LEDs
Slope down. This is the time during which the current
reaches its minimum value and the arc is extinguished (0-10
sec.).
