Use the adjusting dial to set the selected parameter to the desired value. The para-
meter value is displayed in the digital display located above it.
The a-dimension, sheet thickness, welding current, wire feed speed and welding
voltage parameters are directly interlinked. It is only necessary to alter one of the
parameters, as the other parameters are immediately adjusted to match.
All welding parameter set values that have been set using the adjusting dial or but-
tons on the welding torch remain stored until the next time they are changed. This
applies even if the power source is switched off and on again in the meantime.
7
Open the gas cylinder valve
8
Set the shielding gas flow rate:
Press the Gas test button
- Turn the adjusting screw on the underside of the pressure regulator until the
pressure gauge shows the required gas flow rate
CAUTION!
Risk of injury and damage from electric shock and from the wire electrode
emerging from the torch.
When pressing the torch trigger:
▶
keep the torch away from your face and body
▶
do not point the welding torch at people
▶
make sure that the wire electrode does not touch any electrically conducting or
earthed (grounded) parts, such as the housing, etc.
9
Press the torch trigger and start welding
Corrections dur-
ing welding
In order to obtain the best possible welding results, the following parameters can be cor-
rected in certain circumstances:
Arc length correction
for correcting the arc length
- shorter arc length
0 neutral arc length
+ longer arc length
Droplet detachment correction/arc force dynamic correction/arc force
dynamic
MIG/MAG pulse synergic welding:
for continuous correction of the droplet detachment energy
- lower droplet detachment force
0 neutral droplet detachment force
+ higher droplet detachment force
MIG/MAG standard synergic welding:
for influencing the short-circuiting dynamic at the instant of droplet transfer
- harder, more stable arc
