INITIAL INSTRUCTIONS
All "parameters" are set by the use of only one control
knob. These parameters include current, pulse time,
slope-up time, etc.
This control knob is positioned below a digital display
which shows the value of the parameter being set. The
unit of measurement of the parameter is shown at the
right hand side of the digital display.
Change or view the setting of a parameter by pressing
the knob of the parameter in question until the LED at
the parameter symbol is lit.
Also the parameters with on/off function, e.g. TIG
ignition method, can be chosen by pressing the knob
of the parameter in question. The chosen function is
shown with a LED.
Storage of parameters
The machine memorises all settings when the mains
input voltage is switced off, thus ensuring that the
same machine settings are available when the
machine is switched on again.
The exact adjustments in the two welding processes
(MMA electrode and TIG) are stored as well, so that
shifting from one welding process to another does not
require a new current setting.
Setting of the machine
The following describes in detail the operation of the
machine.
Welding current
On pressing this keypad the control knob can be
used to set the welding current unless however that,
the machine has been set to external adjustment.
After the welding process has stopped, the adjusted
current is shown on the display, during welding, how-
ever, the actual welding current is shown. During pulse
welding an average welding current is automatically
shown when shifting between welding current and
base current becomes faster than possible viewing.
Setting of welding jobs
This function enables storage of often used
machine settings and shift from one complete setting
to another. By pressing the keypad the display shows
a "P" and a number: "1", "2" etc. Each number is a
setting of all parameters and functions of the machine.
It is therefore possible to have one setting for each
welding job for which the machine is used. The control
knob is used for shifting between these settings.
During shifting it is possible to see both process and
the other on/off-functions in each setting. Change of
setting is not possible during the welding process. The
setting selected is effected by releasing the keypad. It
is possible to store 10 settings in MMA and 10 settings
in TIG.
Welding voltage
The welding voltage indicator is illuminated for
reasons of safety and in order to show if there is
voltage on the electrode or the TIG torch.
