following:
• The power supply
• The ow of compressed air
Further measures are described in the operating
instructions or in the documentation of other peripheral
devices.
5.7 Operation safety
Please study these operation safety instructions and
respect them when installing, operating, and servicing
the machine.
The welding arc and spatter
The welding arc harms unprotected eyes. Also be careful
with reecting ashes from the arc. The welding arc and
spatter burn unprotected skin. Wear 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 sucient 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.
Cables
Always check the cables before operating the equipment.
Replace damaged cables without delay.
Damaged cables may cause injury or start 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.
Fire can break out from sparks even several hours after
the welding is done!

Packaging for return of
the goods
Check that the shipment is correct by referring to the
shipping note.
Check the package and components for damage (perform
a visual inspection).
If the goods have been damaged during transport, contact
the last carrier immediately. Keep the packaging (for
possible checks by the carrier).
Use the original packaging and the original packaging
material. If you have questions about the packaging and
safety during shipment, please consult your supplier.
The holding force of the inserted springs is directly applied to the release ange
and xes the switching axis, which is positioned by three pins, in the zero position.
In the event of collision, the switching axis tips over, the release ange pushes the
spring plate toward the base of the housing, and the trigger is actuated by the
spring plate’s actuating mechanism. The applied switching voltage is interrupted.
