2. INSTALLATION
The product is packed in specially designed transport
cartons. However, always make sure the products have not
been damaged during transportation prior to this.
Product packaging material is recyclable.
When moving the welding machine, never pull it from
the welding gun or other cables. For lifting the power source
and the robot interface unit, use the recesses at the both
ends of the robot interface unit.
Detailed installation instructions and the technical
information that is out of the scope of this manual are
found in the A7 MIG Welder Integration guide.
Operating environment
The machines included in the system are suitable for both
indoor and outdoor use. Always make sure that the air
ow to the machine is unrestricted. The recommended
operating temperature range is -20…+40°C.
Positioning the machines
Place the machine on a sturdy, level surface that is dry
and will not allow dust or other impurities to enter the
machine´s cooling air ow. Preferably, situate the machine
in a suitable carriage unit so it is above oor level.
• The surface inclination may not exceed
15 degrees.
• Ensure the free circulation of the cooling air.
There must be at least 20 cm of free space in
front of and behind the machine for cooling-air
circulation.
• Protect the machine against heavy rain and direct
sunshine.
Do not operate the machine in the rain.
Never aim the spray of sparks from a grinding machine
toward the equipment.

Robot mounts
The A7 MIG Gun 500-w and 500-g are mounted to the
welding robot using special robot mounts. There are three
types of robot mounts available: robot mountType 1,Type
2 and Type 3.
Figure 3.12 Robot mount T1
The robot mount Type 1 serves for accommodating a
welding gun in exact position. The mount is fastened to
the robot with a cylinder head screws and a robot ange.
Figure 3.13 Robot mount T2
The robot mount Type 2 is used for connecting the robot
and the welding gun. The device acts three-dimensionally
and is adaptable to all types of robots and for handling
machines via a robot ange.

The A7 I/O Device 4/4 is a general-purpose digital input
and output device that can be used to control external
devices, such as a torch cleaning station. It is capable of
driving +24 V logic signals, relays, and valves, and reading
logic states, switches, and digital sensors. Inputs are read
and outputs written by a robot.
The A7 I/O Device 4/4 has 4 inputs and 4 outputs by default.
It can be extended by A7 I/O Extension Card 8/8 that is
available separately. The extension card has additional 4
inputs and 4 outputs, resulting in the total of 8 inputs and
8 outputs when equipped.
See the A7 MIG Welder Integration guide for electrical
characteristics and more detailed information on the I/O
device connection and conguration.

OPERATING MANUAL
4. USING THE WELDER
4.1 Basic controls
Main switch
When you turn the on/o switch into position 1, the
main power indicator is illuminated and the welder
system starts a power-up sequence. The system is ready
for use when the setup panel is ready. Always turn the
machine on and o with the power source mains switch.
Never use the mains plug as a switch.
Indicator lights
The indicator lights of the machine report its operational
state: When the green main power indicator is on, it
indicates that the machine is switched on. When the
orange warning indicator light is on, the machine is
overheated. This is due to a higher than regular working
load exceeding the rated duty cycle. The cooling fan
continues to cool the machine down. When the light
goes o the machine is ready to weld again.
Cooling fans
The A7 MIG Power Source incorporates two
simultaneously operating cooling fans. The fans will
start during welding as the machine reaches operational
temperature, and they will run for 1 to 10 minutes after
welding, depending on the heat eect of the completed
cycle.

Menu item Value range Default value Description
1/8 WFSpeed WFS min -
WFS max
From curve Set the wire feed speed in
0.05 m/min steps from 0.5 to
5.0 m/min and in 0.1 m/min
steps above 5.0 m/min.
2/8 WFS max 0.7 - 25.0 m/min *From curve Set the upper limit for the
WFSpeed value.
3/8 WFS min 0.7 - 25.0 m/min *From curve Set the lower limit for the
WFSpeed value.
4/8 FineTuning FineTuningMin
FineTuningMax-
0 Adjust the welding voltage
(arc length) of the welding
curve up and down (0 = no
adjustment).
5/8 FineTuningMax -9.0 … +9.0 +9.0 Set the upper limit for the
FineTuning value.
6/8 FineTuningMin -9.0 … +9.0 -9.0 Set the lower limit for the
FineTuning value.
7/8 Dynamics -9 … +9 0 Control the arc behavior in
short circuit. A lower value
results in a softer arc and
a higher value results in a
rougher arc.
8/8 Pulse current -10 … +15 % 0 % Adjust the pulse current up
and down.
*These are system limits. Actual limits come from the selected welding curve.

min steps above 5.0 m/min.
2/10 WFS max 0.7 - 25.0 m/min *From curve Set the upper limit for the
WFSpeed value.
3/10 WFS min 0.7 - 25.0 m/min *From curve Set the lower limit for the
WFSpeed value.
4/10 FineTuning FineTuningMin -
FineTuningMax
0 Adjust the welding voltage
(arc length) of the welding
curve up and down (0 = no
adjustment).
5/10 FineTuningMax -9.0 … +9.0 +9.0 Set the upper limit for the
FineTuning value.
6/10 FineTuningMin -9.0 … +9.0 -9.0 Set the lower limit for the
FineTuning value.
7/10 Dynamics -9 … +9 0 Control the arc behavior in
short circuit. Lower value
results to softer and higher
value to rougher arc.
8/10 Pulse current -10 … +15 % 0 % Adjust the pulse current up
and down.
9/10 DPulseAmp 0.1 - 3.0, CURVE CURVE Adjust the amplitude of
the wire feed speed, or use
the value from the welding
curve.
10/10 DPulseFreq 0.4 - 8.0 Hz, CURVE CURVE Adjust the frequency of
the double pulse, or use
the value from the welding
curve.
*These are system limits. Actual limits come from the selected welding curve.
