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 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 completed!
Cables
Always check the cables before operating the equipment.
Replace damaged cables without delay.
Damagedcables maycauseinjury orstart are.Connection
cables must not be compressed or make 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.

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.
All elements together form an operating unit that
provides a plasma arc for welding when supplied with
the appropriate operation resources. The welding wire
required for welding is fed through the welding gun
system A7 MIG Gun 500-g all the way to the contact
tip. The contact tip transmits the welding current to the
welding wire, producing an arc between the welding wire
and work piece. The light arc and the molten pool are
protected by the inert gas (MIG) or active gas (MAG).
10.1 The neck
Standard A7 MIG Gun 500-g necks are available in the
following geometries: straight, 22°, 35°, and 45° bends.
Special designs will be manufactured upon request,
depending on the application.
The uniform interface at the connecting module makes all
torch necks compatible with one another.
10.2 The connection module
The connection module establishes the connection
between the welding torch and the hose assembly.
10.3 The mount
The mount is used to attach the welding gun system to the
robot via the Kemppi robot mount.
10.4 The hose assembly
The gas-cooled hose assembly provides the welding torch
with all components required for welding, such as welding
current, shielding gas, and air.

12. OPERATION
Shortness of breath and poisoning caused by inhaling
phosgene gas
Phosgene gas is formed during the welding of work pieces
that have been degreased with chlorine-containing
solvents.
Do not inhale fumes and vapors.
Ensure a sucient supply of fresh air.
Rinse the work pieces with clear water prior to welding.
Do not place degreasing baths containing chlorine in the
vicinity of the welding area.
Risk of burns
During welding work that sprays sparks, glowing work
pieces or hot slag can produce ames.
Check the work area for seats of re.
Make suitable re-extinguishing materials available in the
work location.
Allow the work pieces to cool down after welding.
Before performing welding work, fasten the ground clamp
properly to the work piece or the welding table.
Dazzling of the eyes
The arc produced by welding may damage the eyes.
Wear suitable protective clothing and eye protection.
The welding torch may only be operated by qualied
personnel.
Ensure that all required parameters, such as the welding
current and wire feed, have been set at the welding power
supply in accordance with your welding task.
12.1 The welding process
This section describes the welding process.
Proceed as follows:
1. Open the shielding gas cylinder.
2. Switch on the power supply.
12.2 Completing the welding process
