T - Knob
Adjusts the welding current - LED P.
In addition, combined with the K push-button, it adjusts other
welding parameters
LED Q - Thermal protection.
It lights when the operator exceeds the duty cycle or
percentage intermittence allowed for the machine and
simultaneously stops the current output.
N.B. Under this condition the fan goes on cooling the
power source.
S – Display
Normally displays the arc voltage in relation to the current
welding process.
When setting the cooling unit operation, it displays the status
of this unit.
R – Display
Displays the welding current and the settings selected by
means of the push-button K and adjusted via the knob T.
In the machine blocking procedures (see 2.3.2), it displays:
-
Three flashing or steadily lit points
-
The abbreviations E1 E2 E3 E4
-
The abbreviation H2O.
U - Selector switch for programs in memory.
Selects and saves the programs in memory.
The welding machine can save nine welding programs
P01.....P09 and call them up via this button. A working
program PL is also available.
Selecting
When this push-button is pressed briefly, the R display shows
the program number next to the one in use. If this has not
been saved, the message will flash, otherwise it remains
steady.
Saving
Once the program has been selected, hold down for more
than 3 seconds to save the data in memory.
To confirm this, the program number on the R display will
stop flashing

3.3 GENERAL NOTES
Before using this welding machine, carefully read the standards
CEI 26/9 - CENELEC HD 407 and CEI 26.11 - CENELEC HD
433. Also make sure the insulation of the cables, electrode
clamps, sockets and plugs are intact, and that the size and
length of the welding cables are compatible with the current
used.
3.4 MMA WELDING (MANUAL METAL ARC)
- This welding machine is suitable for welding all types of
electrodes, with the exception of cellulosic (AWS 6010)*.
- Make sure that the switch N1 is in position 0, then connect the
