Control knob
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 in the right side of the
control panel. The digital display shows the value of
the parameter being set. The unit of measurement of
the parameter is shown on the right side of the digital
display.
A parameter can be selected by means of the relative
keypad in the relevant section. A bright indication light
indicates the parameter selected. The control knob is then
used for setting a new value.
Storage of parameters - programs
This function enables storage of programs
(often used machine settings) and shift from one
complete program to another. By pressing the keypad the
display shows a “P” and a number: “1”, “2” etc.
Each number includes a program with all parameters and
functions of the machine. It is therefore possible to have
one program for each welding job for which the machine
is used.
It is possible to store 64 settings in each welding process
(MMA, TIG and PLASMA) = 192 program settings.
Each program can be selected by:
1. Choose between MMA, TIG or PLASMA.
2. Select program number (P01…P64). The control knob
can be used for shifting between the programs when
the key pad is kept pressed down.
The latest used program setting in the relevant program
group (MMA, TIG and PLASMA) will be shown when the
program key pad is selected.
Reset of welding programs
Select the program that needs to be reset to factory
settings. Then keep the -key pad pressed for 5 seconds
without turning the encoder.
The program has been reset when the current program
number is flashing on and off in the display and the
-key pad can then be released again.

Welding current
The key pad can be used to display the welding
current. Adjustable from 5A to 350A in Plasma mode
and 5A to 500A in TIG/MMA mode. After the welding process
has stopped, the adjusted current is shown on the display.
During welding, however, 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.
Units for parameters
Units of measurement of the selected parameter.
Selection of welding process
Electrode welding (MMA)
Is used for selection of electrode welding. It is not
possible to change welding process during welding.
TIG welding
Press this knob to activate TIG process
PLASMA welding
Press this knob to activate TIG process
TIG and PLASMA welding
TIG and PLASMA welding
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. Please note that
values higher than 100% generate a Start Amp bigger than
welding current.
