Assembly Instructions

The following shielding gas hose must be connected to the fit-
ting:
■
Outside diameter: 8 mm
■
Inside diameter: 6 mm
Linear gas supply with a lateral MDE nozzle
Using this nozzle, linear supply of the protective gas is possible
while, at the same time, metal vapor effect can be eliminated
with a lateral MDE nozzle.
Prerequisites:
■
cw laser device.
■
Focal length of lens f = 150 mm, f = 200 mm, f = 250 mm
and f = 300 mm.
1 Linear nozzle
2 Lateral MVE nozzle
3 Outflowing MVE gas
Fig. 2-39
The linear nozzle is suitable for welding linear welds:
■
Butt joint.
■
Fillet seam.
The linear nozzle can be fastened to the crossjet receptacle.
For more detailed information, see dimensional drawing doc. no.
22-51-01-A34-BX.
The distance between focusing optics and the workpiece can be
adjusted as required.
It must be made sure that the linear nozzle is not in the beam
path.
