Connect the gas cylinder

1. Place gas cylinder on Powerbox and
secure with chain against turning
over.
2. Connect gas hose to the SDV (40).
Note:
The SDV is fitted with a solenoid
valve. Gas flows only during the welding
process.
3. Connect gas hose to pressure regu-
lator.

7. Default Machine Settings

7.1 Control unit for default
machine settings
1. Open SDV cover.
2. Stipulate the welding process set-
tings with the selector switches:
− the type of electrode wire (Wire
Type)
− the wire diameter (Wire Diame-
ter)
− the type of shielding gas (Gas
Type)
− the operating mode (Mode Selec-
tion)
− the burnback timer (Wire burn-
back control).
7.2

Charateristics curves

The default charateristics curves, sup-
plied with the machine, are selected by
the settings made at the control unit for
the default machine settings.
Example: Charateristics curve for
MIG brazing
MIG brazing is suitable for brazing gal-
vanized sheet metal. To select this cha-
rateristics curve, the following settings
must be made.
16
Wire type:

Gas type:

Operating mode: MIG/MAG or
40
Note:
The allocation of settings and
corresponding charateristics curves is
shown on the label affixed to the inside
of the cover.
As an option, any charateristics curve
can be changed by a PC via the connec-
tor socket for programming.
Note:
Detailed information about pro-
gramming of characteristic curves is
available from the service centre in your
country (see address listing on back
cover of the spare parts list).
The operating mode PROGRAMM is
reserved for charateristics curve pro-
gramming.
7.3 Gas type
I1 = 100% Argon
M13 = 0-3% O2, balance Argon
M12 = 0-5% CO2, balance Argon
M21 = 0-25% CO2, balance Argon

Pulsed MIG/MAG

2-step = manual welding operation:
1. Actuate the torch trigger
The welding process starts.
2. Release the torch trigger
The welding process ends.
4-step = continuous welding operation:
1. Actuate and release the torch trigger
The welding process starts.
2. Actuate and release the torch trigger
again
The welding process ends.
4-step+H = continuous welding operation +
High-Start:
1. Actuate the torch trigger
Welding current and wire feed
speed are increased by 25% over
the set values.
2. Release the torch trigger
The welding process runs at the set
values.
3. Actuate the torch trigger again
The welding process will then run at
a reduced welding current (rated
current reduction).
4. Release the torch trigger
The welding process ends.
Cu/CuZn
I1 (Argon) or
M12 (0-5% CO2,
balance Argon)
pulsed MIG/MAG.
ABS (reduced value for end crater fill-
ing)
With the ABS function the parameters of
the charateristics curve are reduced for
the pulsed MIG/MAG welding process
for best welding results. The end of the
weld is welded with reduced power and
end craters are prevented.
The ABS function is dependent on the
selected wire type.
7.5

MIG/MAG

2-step = manual welding operation:
1. Actuate the torch trigger
The welding process starts.
2. Release the torch trigger
The welding process ends.
4-step = continuous welding operation:
1. Actuate and release the torch trigger
The welding process starts.
2. Actuate and release the torch trigger
again
The welding process ends.
Integrated softstart
The machine features an integrated soft-
start for the MIG/MAG and pulsed MIG/
MAG welding modes.
As long as there is no welding current
flow, the electrode wire is fed very
slowly. This prevents to much wire emer-
gence. As soon as the arc starts the wire
is fed at the preset speed.
Note:
In position EXT (MIG/MAG and
pulsed MIG/MAG) an external control
can be connected.
If this operating mode is selected and no
external control connected, the machine
operates in 2-step mode.
7.6

Manual arc welding

ELECTRODE:
After arc start the welding process
run for a brief period with an
increased welding current (inte-
grated Hot-Start).
The welding current increase for the
intergrated Hot-Start is 25% of the
set welding current.
Example:
Welding current = 100 A
Current increase = 25%
=> Hot-Start current = 125 A.
7.7

FBZ Burnback time

If set correctly, the burnback timer keeps
the electrode wire from sticking to the
weld pool. Adjustment is made with the
selector switch Burnback Time. The
scale values of 1-10 correspond to a
burnback time range of 0...0.4 s.
