The welding arc and spatter
The welding arc harms unprotected eyes. Also be careful
with reected ashes from the arc. The welding arc and
spatter burn unprotected skin. Use safety gloves and
protective clothing.
Danger of re or explosion
Pay attention to re safety regulations. Remove ammable
or explosive materials from the welding location. Always
reserve sucient re-ghting equipment at the welding
location. Be prepared for hazards in special welding jobs –
for example, the danger of re or explosion in welding of
container-type work pieces.
Fire can break out from sparks even several hours after
the welding is done!
Cables
Always check the cables before operating the equipment.
Replace damaged cables without delay.
Damagedcablesmaycauseinjury orstart a re.Connection
cables must not be compressed or come in contact with
sharp edges or hot work pieces.
The welding power circuit
Isolate yourself by using proper protective clothing, and
do not wear wet clothing. Never work on a wet surface or
use damaged cables. Do not place the MIG gun or welding
cables on the welding machine or on other electric
equipment. Do not press the MIG gun’s switch if the gun is
not directed towards a work piece.
Welding fumes
Make sure that there is sufficient ventilation during
welding. Take special safety precautions when welding
metals that contain lead, cadmium, zinc, mercury, or
beryllium.

9. FUNCTIONAL DESCRIPTION
For cleaning, the torch is clamped with the cylindrical part
of the gas nozzle in the clamping device.The milling cutter,
which is congured to match the gas nozzle and torch
geometry, moves into the gas nozzle’s interior by means
of a stroke movement and removes adhered welding
spatter. At the same time, the gas nozzle interior may be
blasted with compressed air through the cable assembly
(optional). Hereby, the cleaning process is optimized in
connection with an optional anti-spatter application.

10. INSTALLING THE ROBOT GUN
CLEANING STATION
This section describes how to install the Robot Gun
Cleaning Station unit.
Risk of injury due to unexpected start-up
For the entire duration of maintenance, servicing,
unmounting, and repair work, the following instructions
must be adhered to:
• Switch o the power supply.
• Cut o the compressed air supply.
• Pull the power plug.
The parts of the system are depicted in the gure below.
Proceed as follows:
1. Connect the two hoses (4 and 8) to the applicable
bottles to put the injection unit of the welding
torch into operation.
All other connections for compressed air are pre-mounted
at the factory.
Ensure that the non-return valve (6) is attached to the
suction hose (4).
2. Connect the device through the compressed-air
hose.

OPERATING MANUAL
Figure 8: Connection for compressed air, DN10
The operating pressure should be 6 bar. If the supply
pressure for compressed air is under 6 bar, the cutting
capacity of the wire cutter and the speed of the
compressed-air motor will be lower. This will reduce the
performance of the torch-cleaning station.
We recommend to operate the device with cleaned and
oiled compressed air.
An applicable maintenance unit is available as an
accessory.
10.1 Connecting to electricity
This section describes how to connect the Robot Gun
Cleaning Station to electricity.
Proceed as follows:
1. Connect the cleaning station of the welding torch
to the power supply through an integrated plug
connection.
The necessary control signals too are transmitted through
this plug.

gasket, tting the gas nozzle of the welding torch.
Figure 11: Rubber gasket
1. Mark the gas nozzle diameter of the welding torch.
2. Loosen the cover (1).
3. Attach the rubber gasket (2) to the cover (1).
Insert the rubber gasket (2) into the cover (1) with light
pressure. The special design of these two components
prevents unintentional dropping of the rubber gasket.

Make sure that the welding torch / gas nozzle is placed
concentrically over the injection unit.
Proceed as follows:
1. Place the welding torch (1) over the injection
opening.
2. Move the welding torch (1) slowly downwards (in
the direction of the arrow).
Hereby, the rubber gasket is "opened." The immersion
depth of the welding torch is limited by the stroke of the
injection unit.
3. Move the gas nozzle, with the front side toward the
thrust ring.
Move the welding torch further down to activate the
injector function.
Pay attention to the max. stroke of the injection unit.
Figure 13: Stroke movement of the injection unit
Pay attention to the max. stroke movement for
injection.
• The max. stroke travel (traversing movement
of the welding torch) should not exceed 6
mm. We recommend a maximum injection
impulse of 3 s. The injection pulse is reset
upon moving out of the injection unit.
• Use the adjusting screw (8) to adjust the
amount of anti-adhesives per injection
impulse.
• The residual oil of the anti-spatter
application from the injection unit is
collected in the drain bottle (7) and can
be reused after it is puried of particulate
matter.
• Pay attention to the max. stroke movement
for injection.
4. Manually activate the device via the cover, to set
the dosing of the anti-adhesives.
When setting the anti-spatter adjustment manually,
wear safety goggles.
You can activate the injection pulse by pressing down
lightly on the cover. The injection pulse should be activated
for a maximum duration of two seconds.
You can assess the amount of atomized anti-spatter
substance by the spray mist produced.
You can increase or reduce the amount of anti-spatter
substance by using the adjusting screw (8).
A small amount of anti-spatter substance is sucient
to achieve the desired eect.

Proceed as follows:
1. For better access, loosen the protection plate and
move it backwards.
2. Move the welding torch to the cutting position.
Pay attention to the desired stick-out length.
3. Move the free wire end to the xed cutter (at the
lower cutting edge).
4. As soon as you have programmed the desired
cutting length, the protection plate must be moved
forward again. The gap between the xed cutter
and the protection plate should be < 4 mm.
If the cutting plates reach their wear limit (possible results
include poor cutting quality, jamming of the device, and
incomplete cutting), the cutting plates do not need to be
replaced at once.
Program a new cutting position in a new place in the area of
the cutting plates.

concentric with the tool axis (milling cutter axis)
over the cleaning station (3).
2. Approach the clamping position. Make sure that
the cylindrical part of the gas nozzle (2) rests evenly
against the clamping prism (1).
The clamping position in the direction of the milling
cutter axis should be in the cylindrical part of the gas nozzle.
The clamping position (5) can vary, depending on the gas
nozzle type.
10.8 Setting up the compressed-air motor
Set up the compressed-air motor with the aid of the gure
below.

Before you can set up the compressed-air motor in its
nal position, the welding torch has to be positioned in the
cleaning station. See Section 9.7.
The motor stroke needs to be in the lower position (8) (stroke
down).

10.9 Adjusting the height
This section describes how to set up the clamping position.
The parts of the system are depicted in the gure below.

See also Section 9.8.
The device has to be depressurized during set-up.
Proceed as follows:
1. Loosen the clamping screws, M8×45 (6), using an
Allen key (8). Meanwhile, hold the compressed-air
motor (8).
2. Move the compressed-air motor (8) to the upper
stroke position, as shown in Figure 20 (A) (the
compressed-air motor can be moved into the
upper stroke position manually).
3. Move the compressed-air motor (8) upwards in the
fastener (9) until the front side of the milling cutter
(5) hits the front side of the gas nozzle (4). See
Figure 20 (B).
4. Fasten the clamping screws, M8×45 (6), of the
motor fastener (9) (minimum tightening torque:
20 Nm).
