Fault symbols
The indicator next to the icon blinks when other
types of errors occur. At the same time a fault symbol is
shown in the display.
Selected error codes:
(The error code can be reset by pressing the MMA-key pad.)
Torch cooling fault
Cooling fault is shown in case of no circulation
of the cooling liquid due to faulty connection or choking.
Check that the cooling hoses are correctly connected, top up
the water tank and check welding hose and branches.
Mains supply fault
The icon will be shown, when the mains
voltage is to high. E04-01 will be shown when the mains
voltage is to low.
Connect the welding machine to 400V AC, +/-15% 50-
60Hz.
OTHER TYPES OF FAULTS
If other fault symbols are shown in the display, the machine
shall be switched off and then on to dispose of the symbol.
If the fault symbol is shown repeatedly, repair of the power
source is required. Contact your distributor with information
of the fault.

The parameters can be adjusted with the control
knob after they are shown on the display. Press the
relative key to select the parameter. The relevant LED will
illuminate.
Pre-flow [s]
Pre-flow is the period of time for which gas flows
after the torch switch is pressed and before the HF
arc is established. Variable 0-10 sec.
In the LIFTIG process the period is the time until the torch is
lifted away from the workpiece.
Start Amp [A%]
Immediately after the arc has been established, the
machine regulates the welding current to the value
stated in the Start Amp parameter. Start Amp is set as a
percentage of the required welding current and is variable
between 1-200% of the welding current. Please note that
values higher than 100% generate a Start Amp bigger than
welding current.
Slope-up [s]
Once the arc has been established, the
welding process enters a slope-up
stage during which the welding current is
increased in linear fashion from the value stated
in the Start Amp parameter to the required
welding current. The duration of this slope-up
time is variable 0-20 sec in steps of 0.1 sec.
Second current level
Adjustable from 10 to 200% of welding
current. It is activated in four-times only
by pressing and releasing quickly the torch
trigger. Please note that values bigger than
100% generate a secondary current bigger than
welding current.
Slope-down [s]
When welding has stopped by
activating the trigger, the machine
enters a slope-down stage. During this stage
current is reduced from welding current to Final
Amp over a period of time called the slope-down
time and variable 0-20 sec in steps of 0.1 sec.
Final Amp [A%]
The slope-down stage is completed
when the current level has fallen to the
value stated in the Final Amp parameter. In 4-
times it is possible to continue in Final Amp
mode until the trigger is released. Final Amp is
stated as a percentage of the required welding
current and is variable between 1-90% of the
welding current.
Spot time
The spot time in TIG is the time from
the end of slope up to beginning of
slope down. Therefore, during spot time the
machine is welding with the adjusted current.
The LED flashes on and off when the function is
active.
Amp
Set welding
current
Set the timer before igniting the arc. The torch
trigger, depending from the selected torch mode
can interrupt the spot welding time.
Variable 0.01-600 sec. The function is
disconnected when the time is set to 0 sec.
When used during tack welding, the timer can be
set from 0.01 sec to 2.5 secs (See TIG-A-
TACK).
