Anti-freeze
This machine is provided with an anti-freeze control.
The anti-freeze-control reduces the current when the
electrodes stick to the weld piece. This makes it easier to
break off the electrode and welding can continue.
Reset to factory settings
of all programs
It is possible to recall all factory standard
parameters. In this case all programs in the machine will
be reset to the following value:
• MMA current 80A
• MMA hotstart 50%
• MMA arc power 50%
• TIG Current 80A
• TIG Spot Current 80A
• Pre-flow 0.0 sec
• Post-flow 3.0 sec
• No slope-up/slope-down
• Start amp 40%
• Stop amp 20%
• Second Current level 50%
• Base amp 40%
• Fast pulse frequency 49Hz
• Pause time = Pulse time = 0.1 sec
• AC-T-Balance (AC) 65%
• Electrode Pre-heating (AC) 5
• Frequency (AC) 50Hz
• AC-I-Balance (AC) 100%
The reset procedure is as follows:
Switch off the machine and wait until display is
extinguished.
Press the following key pads simultaneously:
Switch on the machine and keep the above keys pressed
until the display shows "X.XX". Then release the keys.
X.XX is the software version of program.
Reset to factory settings of a single program
Select the program in question, then press and
keep pressed the
turning the encoder. The display will show the current
program number by flashing the segments to confirm the
reset. Then you can release the key pad and the current
program will be reset to factory settings (see values
above).

Submenu for wire feeder
Exit from submenu
Active control of CWF
0 = no CWF (default)
1 = at least one CWF
Submenu containing different options:
Exit from the submenu (go back to main menu)
Programs LOCK
Protection of programs P3 to P64 (mode 1)
or P1 to P64 (mode 2) for all procediment against
unintentional change of:
• Welding currents, slopes, timing
• Trigger selection 2T/4T
• Current reference EXT/Internal
• Pulsations
It is still possible to select different programs and
welding procediment. Programs P1 and P2 are
unlocked (mode 1), permitting full control of relative
parameters. When pressing locked key pads or rotating
the encoder for locked parameters, the display will
flash "PG.L." to remember the active protection.
0 = unlocked (default setting)
1 = locked P3 to P64
2 = locked P1 to P64
Panel LOCK
Complete lock of box. All keypads and Encoder
are disabled. When pressing locked key pads or
rotating the encoder, the display will flash "PA.L." to
remember the active protection.
