3.2 DESCRIPTION OF THE EQUIPMENT

AL - Process selector switch
This button is used to choose the welding process
(MMA or TIG). The selection changes each time it is pressed.
The LEDs light alongside the various symbols to display your
choice.
B - MMA welding LED
This machine can weld all types of coated electrodes except
cellulosic. With this process the current is adjusted using the
knob O, and it is possible to adjust the "arc force" (LED AN)
and "hot start" function (LED AM).
AH - Continuous TIG welding LED
AI - Pulsed TIG welding LED
The pulse frequency is adjustable from 0.16 to 500Hz (LED

T), the peak current and the base current may be activated
via the LEDs X and W, respectively, and are adjustable using
the knob O.
From a pulse frequency of 0.16 to 1.1 Hz, the display P alter-
nates displaying the peak current (main) and the base cur-
rent. The LEDs X and W light alternately; beyond 1.1 Hz the
display P displays the mean of the two currents and the
LEDs X and W both remain lit.
A - Mode selector switch
The selection changes each time it is pressed, and is
displayed by lighting the LED C or D together with other
LEDs displaying the welding mode.
C - Arc starting without high frequency LED.
To light the arc, press the torch trigger, touch the workpiece
with the tungsten electrode, and lift it again. This move must
be quick and decisive.
D - Arc starting with high frequency LED.
To light the arc, press the torch trigger: a high voltage/fre-
quency pilot spark will light the arc.
