31. Functional description
2-cycle, 4-cycle, spot, special program (MC 3-4)
By tipping on the control key (3), the box change between 2-cycle, 4-cycle, 2-cycle-spot mode or a
special program. The Led above shows, which function is activated.
Material selection (material, gas, wire diameter) (MC 3-4)
With a short tip on the control key ‘material’, the actual material appears in the 3 displays. In the left
display is the material (e.g. steel), in the middle display the gas (e.g. Co2) and in the right display the
wire diameter (e.g.1.0mm). By rotating the left control knob, it is possible to change the material. The
last material shown in the displays will be accepted.
Automatic / manual mode (MC 3-4)
Pressing the control key ‘Auto/Hand’ longer then 1 second, the machine change between
automatic or
manual mode. In automatic mode, all welding parameters are preselected by the box for a good
welding result.
In manual mode, the welder must adjust the wire speed with the left control knob and the welding
voltage (welding power) with the middle control knob.
Power selection / step preview / material thickness (MC 3-4)
In this type of machines, the welding power can only be changed by the voltage-step switches.
In automatic mode the wire speed and choke will always be modified for a perfect welding result.
To find the optimal welding step, there are 2 options:
1) Use the material thickness. Tap the knob mm (MC 3) or ► (MC 4) until the LED mm (MC 3) is on or
thickness (MC 4) flashes. Now, the required material thickness can be set by turning the left knob
on MC 3 or pressing the keys ▲ ▼ on MC 4 until the value is shown in the right display. At the same
time the required welding step appears in the middle display. Example: Level 1-10 for 2.0mm.
2) Use the welding voltage or welding current. Tap the control knob mm (MC 3) or ► (MC 4) until the
welding voltage and the welding current appears in the middle and right display. Now the required value
can be set by turning the left knob on MC 3 or pressing the keys ▲ ▼ on MC 4 until the value is shown
in the displays. Now again as described in point 1 tap on the control knob mm (MC 3) or ► (MC 4) to
set up the LED mm (MC 3) is on or thickness (MC 4) flashes.
The welding step and the material thickness are displayed.
This process can be repeated as often.
This step preview indicator is a good starting point, but for the upcoming welding job too be change.
Cooling medium - flow indicator (MC 3)
To show the actual flow rate of the cooling medium in the cooling system, press the control key ‘l/min’
long. The LED l/min is light. In the right display the actual value is shown (e.g. 1.35).
If the flow rate is lower then 0,25 l/min for more then 5 seconds, the machine stops and in the display
the error ‘Err’ and ‘H2o’ will appear.
It isn’t possible to weld. Switch the machine off, repair the water error, and switch on the machine.
Function Fx (MC 3)
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 ‚- 80 harder’ to ‚+ 80 smoother’ 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
- spot time (SPt): 0,5 to 10 seconds
- Code (CodE): to block the control unit (see next page)
