Display AL.

In all welding processes, it numerically displays the 

selections made via the selection key 

AE

 and adjusted 

via the knob 

AI

. 

For the welding current (LED 

AD

) it displays the amperes.

For the wire speed (LED 

AC

) it displays the meters per 

minute.

For the thickness (LED 

AB

) it displays the millimeters.

For (LED 

AA

) it displays the set program number.

In the service functions the following are selected:

 TRG, 

SP, HSA, CrA, PrF, PoF, Acc, bb, L, Dp, PPF,  Ito, Fac.

For the parameters within the service functions that are 

shown on the display 

AM

, see the paragraph on 

service 

functions.

When the machine is in the warning mode, it displays 

a  flashing warning (exemple: 

OPN

 if the lateral  panel is 

open. When the machine is in the error mode it displays  

Err

.

Display AM.

Displays by the number: in synergic  MIG the arc length 

and in conventional MIG the welding voltage.

For the welding voltage (LED 

AH

) it displays the Volts. For 

the arc length (LED 

AH

off) it displays a number between 

9.9

 and 

+9.9

, 

0

 being the recommened value.

For the parameters in the MIG service function, that are 

shown on the display 

AM

, see the paragraph on 

service 

functions 

.

When the machine is in error mode it displays the 

corresponding error code between 1 and  99.

Selection key AO.

Each time this key is pressed, the selected process is 

shown by LED 

AP/AQ/AR

.

LED AP  Pulsed MIG.

Shows that the selected process is the synergic MIG  

Pulsed.

LED AQ  SYNERGIC MIG.

Shows that the selected process is synergic MIG.

LED AR  CONVENTIONAL MIG.

Shows that the selected process is conventional MIG.

Selection key AU.

Each brief pressure selects 2 stages mode (MANUAL) and 

the 4 stages mode (AUTOMATIC), the selection is shown 

on the display 

AL

.

In the 2 stages mode  the machine begins welding when 

the welding torch trigger is pressed, and stops when 

released.

In the 4 stages mode to begin welding press and release 

the welding torch trigger; to interrupt, you must press and

until a sound will confirm that it has been saved 

and the selected number stops flashing.

To restore the saved number just briefly press key 

AV

 and 

restore the number by means of  knob 

AN

. Up to 99 pairs 

od current/voltage values may be saved.

To delete a saved number, press for at least 3 seconds
