Function Fx (MC 1)
In stand-by mode (not during welding):
By tipping short on the control key ‘Fx’ the following functions can be changed for
each welding curve (only in stand-by mode):
Operation Mode MIG:
- choke (Choc):
step less correction of the welding choke
from ‚+ 15 smoother’ to ‚- 15 harder’ then normal ‘0’
- start - speed (StS):
10 to 100% of the welding speed
- wire burn back (bUb):
-60ms (long, pointed) to +90ms (short, ball wire end)
- gas pre flow time (PrG):
0,0 to 1,0 second
- gas post flow time (PoG):
0,5 to 10 seconds
- *Crater Hotstart current (CSC):
-50% to 100% of the welding current
- *Crater Hotstart time (tCSC):
0,1 to 5,0 seconds
- *Crater end current (CEC):
-100% to 50% of the welding current
- *Crater end time (tCEC):
0,1 to 5,0 seconds
- *Slope down speed (SLO):
1Volt / second (slow) to 20Volt / second (fast)
- spot time (SPt):
0,5 to 10 seconds
- Code (CodE):
to block the control unit (chapter 7)
* MC 1 only active with function crater (LED S)
Operation Mode MMA:
- Hotstart (HSt):
0 to 200% of the welding current
- Arcforce (Arcf):
100 to 250% of the welding current
Operation Mode TIG:
- gas post flow (tPoG):
2 to 20 second
- Down slope (dSLP):
0,1 to 10 seconds
The values can be changed by rotating the middle knob (MC 1).
If the value is not changed for more then 2 seconds, the value will be stored.
During welding:
Operation mode MIG:
During the welding operation, the choc function is accessed and can be modified by tapping the button Fx.
The left display shows Choc, in the middle display is the current value.
Now, with the middle knob, the value can be changed between -15 and +15.
By another tap on the Fx button, the arc length correction is shown in the middle display.
Now, with the middle knob, the value can be changed between -3.0V and + 3.0V.
