Front Control Panel - Selco Quasar 270 Instrucciones De Uso

3.2 Front control panel

Quasar 270-350
Quasar 270 RC - 350 RC
1 Power supply
Indicates that the equipment is connected to the mains
and is on.
2 General alarm
Indicates the possible intervention of protection devices
such as the temperature protection.
3 Power on
Indicates the presence of voltage on the equipment
outlet connections.
4 Voltage Reduction Device
Shows that the no-load voltage of the equipment is
controlled.
5 7-segment display
Allows the general welding machine parameters to be
displayed during start-up, settings, current and voltage
readings, while welding, and encoding of the alarms.
6 Main adjustment handle
Allows the welding current to be continuously adjusted.
7 Main adjustment handle
Allows adjustment of the selected parameter on graph 8.
The value is shown on display 5.
Allows entry to set up, the selection and the setting of
the welding parameters.
8 Welding parameters
The graph on the panel allows the selection and adjust-
ment of the welding parameters.
Welding current
Permits adjustment of the welding current.
Parameter set in Amps (A).
Minimum 3A, Maximum Imax, Default 100A
Hot start
Allows adjustment of the hot start value in MMA.
Permits an adjustable hot start in the arc striking phases,
facilitating the start operations.
Parameter set as a percentage (%) of the welding cur-
rent.
Minimum Off, Maximum 500%, Default 80%
Arc force
Allows adjustment of the Arc Force value in MMA welding.
Allows a plus or minus dynamic energy response dur-
ing welding, thereby facilitating the operations of the
welder.
Parameter set as a percentage (%) of the welding current.
Minimum off, Maximum 500%, Default 30%
9 Welding process
Allows the selection of the welding procedure.
Electrode welding (MMA)
Basic
Rutile
Acid
Steel
Cast iron
Electrode welding (MMA)
Cellulose
Aluminium
Selecting the correct arc dynamics enables maximum
benefit to be derived from the power source to achieve
the best possible welding performances.
Perfect weldability of the electrode used is not guaran-
teed (weldability depends on the quality of the consum-
ables and their preservation, the operating and welding
conditions, the numerous possible applications, etc.).
