Use of the machine
During welding a heating of various components of
the machine takes place and during breaks these
components will cool down again. When using current
settings above a set value, the machines need
periods when they can cool down.
The length of these periods depends on the current
setting and the machine should not be switched off in
the meantime.
If the periods for cooling down during use of the
machine are not sufficiently long, the overheating
protection will automatically stop the welding process
and the yellow light will come on.
The yellow light switches off when the machine has
cooled down sufficiently, and the machine is ready for
welding. Max. load can be seen in the Technical data.
Definition:
60% max. load by welding means that a cooling
period of 4 minutes is required after welding for 6
minutes at a current setting of the value of 60%
variable intermittent duty; 10 minutes between start of
each welding period must be calculated.
INITIAL INSTRUCTIONS
BOX 1
General instructions for use
All "parameters" are set by the use of only one control
knob. These parameters include current, 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.
In order to display or adjust the parameters of a
particular function, the keypad in the section
concerned with that function is pressed repeatedly
until the indicator light below or next to the relevant
symbol is indicated by a bright light. Adjustment of
setting is then made with the control knob.
Welding current is set by pressing keypad marked
and then using the control knob.
Welding parameters e.g. pulse frequency can be
adjusted during the welding process.
Briefly: Keypads select the functions, the control knob
sets the parameters.
Function selection
As above, selection of a function, e.g. HF-TIG or
LIFTIG, is by means of the keypad in the relevant
section.
The function selected is indicated by a bright light
below or next to the relevant symbol.
CHANGE OF FUNCTION SETTING IS NOT
POSSIBLE DURING THE WELDING PROCESS.
Storage of parameters
The machine memorises all settings when the mains
input voltage is switched 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
