FIXED FUNCTIONS
Some functions are fixed and cannot be connected
and disconnected from the display.
Anti-freeze
(MMA
)
The anti-freeze function is active in MMA. In MMA it
happens that the electrode sticks to the workpiece.
This is registered by the welding machine, and the
current is lowered to 10 A after 1 sec., which makes it
easier to break off the electrode. Welding can then be
continued.
Stop of gas flow in case of fault detection
The machine automatically stops the gas flow to the
torch, turns off the welding current in order to let a
possible arc extinguish and stops the wire feeding in
case of a fault.
Automatic stop of re-ignition
(MIG/MAG)
In case of missing arc during ignition, re-ignition is
automatically stopped after 4 sec.
The arc extinguishes
Welding stops and gas post-flow begins, if the
arc extinguishes during welding. The arc can be
re-established when triggering the torch again.
Display of program version
Software versions can be displayed during start-up by
keeping the -key pad pressed. When the key pad is
released, it is possible to change between display of
1: Wire feed unit software version
2: Welding program software version
3. Power source software version
by means of the right control knob. Press the key next
to the right control knob to return to default display
