BASIC control panel
FIXED FUNCTIONS
The following functions are fixed and cannot be switched
on/off at the control panel.
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 second, which makes it easier to
break off the electrode. Welding can then be resumed.
Gas flow stop in case of fault detection
In case of fault detection, the machine automatically stops
the gas flow to the torch, turns off the welding current, in
order to extinguish any arc, and stops wire feeding.
Automatic stop of re-ignition (MIG/MAG)
If the arc is not established within 4 seconds after start,
the machine automatically shuts down.
The arc extinguishes
If the arc extinguishes during welding, welding stops and
gas post-flow begins. Trigger the torch to re-establish the
arc.
