3.2 DESCRIPTION OF THE EQUIPMENT.

C – Procedure and mode selector switch
This push-button selects the welding procedure (MMA or
TIG) and mode (2-step, 4-step and spot welding).
The selection changes each time the button is pressed.
The LEDs light next to the various symbols to display your
choice.
A LED – MMA (Manual Metal Arc) welding.
This machine can melt all types of coated electrodes, except
for cellulose.
With this process the current is adjusted using the knob Q,
and it is possible to adjust the "arc force" (LED I) and "hot
start" function (LED G).
(manual)
When the torch trigger is pressed, the current begins to
increase over the previously set "slope up" time (N LED on),
until it reaches the value set by means of the Q knob. When
the trigger is released, the current begins to drop over the
previously set "slope down" time (A6 LED on), until it goes
back to zero.
(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.
LED E – TIG spot-welding LED
(manual)
After selecting the welding current (LED O) and the spot
welding time (LED P) using the selector switch H, set the
values using the knob Q.
This welding mode is to be used only if start-up with high
frequency is selected (LED A2 lit). In this welding mode, the
operator presses the torch trigger, the arc lights, and after
the set spot welding time the arc shuts off automatically. To
do the next spot, you must therefore release the torch
trigger and press it again.
Z – 4-step mode selector switch
This push-button selects the welding mode: 4-step with dual
current level, 4-step with with three levels of current and 4-
step SWP special program.
The selection changes each time the button is pressed.
The LEDs light next to the various symbols to display your
choice.
LED V - 4-step TIG welding with dual current
level, (automatic bilevel).
Set the two current levels before lighting the arc:
First level: press the H key until the LED O lights, and adjust
the main current using the knob Q.
Second level: press the H key until the LED A7 lights, and
adjust the main current using the knob Q.
B LED – 2-step TIG welding
D LED – 4-step TIG welding
