Functional description
3.2

Switching on

The BOOSTER.PRO welding unit is switched on at the main switch. For about 2
seconds, all LEDs will light up. Thereafter, the digital display will show for about 2
seconds the machine model and the program number. The welding unit is now
ready for operation.
3.3

Special features of the operating panel

The active processor control makes operation quicker and easier.
All of the set parameters remain saved in the unit when it is switched off at the
main switch. When it is restarted, the parameters are set that were used for the
most recent welding process. To ensure that any changes you make to these
parameters also remain available when the machine is switched off you must
ignite the arc.
3.4

Push and rotating button (R-Pilot)

The push and rotating button [5] is positioned centrally and may be easily
operated by both left and right handed operators alike. Its special receptacle
keeps it very well protected against mechanical damage. The press and rotating
button has no stopper which means that it cannot be rotated too far.
3.5

Digital display

The 3-digits display [6] provides a rapid and easy to view display of the welding
parameters (welding current, HotStart and ArcForce) and all relevant error
messages (see Chapter 7). The control LEDs [7] to the right of the digital display
light up when their unit is selected.
3.6

Push button electrode welding

Use the push button [3] to select the welding process (electrode welding) and the
electrode type used for this welding process. Press the push button [3] several
times to toggle between the electrode types Rutile, Basic or Cellulose: the control
LEDs [4] of the electrode type selected will light up.
Factory-pre-programmed characteristics of all standard electrode types are
already available to ensure an optimum welding process. Simply select the
electrode type to be used, all parameters are available in the memory. You may
start welding immediately, no other adjustments are required. You may also
modify and save each of these parameters, see chapter 3.6.2 + 3.6.3 Hot Start
and Arc Force.
Of course, you may reset the factory settings, see chapter 3.6.5 Resetting to
the factory settings.
When you select the electrode welding method, ensure that no WIG torch is
connected. Otherwise, the digital display will produce the error number „E21"
(see chapter 7.3)
Connect the electrode holder either at the negative pole (-) (welding socket at the
top) or at the positive pole (+) (welding socket at the bottom), depending on the
electrode type and the manufacturer's instructions.
