Control knob
1
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
2
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 DC, MMA AC/DC, TIG DC and TIG AC/DC).
Each program can be selected by:
1. Choose between MMA or TIG
2. Then choose between DC or AC
3. Finally, 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 DC, MMA AC, TIG DC and TIG AC) 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 10 secs without
turning the encoder.
The program has been reset when the current program
number is flashing on and off in the display and the
pad can then be released again.
Welding current/Arc voltage
3
The key pad can be used to display the welding
current. Adjustable from 5A to 350A or 500A
depending on the machine model. 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.
Press the key for 3 seconds to display the arc voltage (valid
ONLY for TIG DC and MMA DC). Press again "A" to display
the welding current.
Use the key pad to return to display of amperage in case of
adjustment of parameters.
