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 indi-
cates 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 exceed-
ing 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 simultaneous-
ly operating cooling fans. The fans will start during weld-
ing 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.

4.4 User identification
4.4.1 Overview
The user identication system enables access control of
individual users. The feature is optional and can be turned
on when needed. Initially, the user identication system is
turned o. The welding system is in the initial state when
it is taken into use for the rst time or after a factory reset.
System conguration, control and monitoring functions
are divided into three access levels. The lowest level (level
0) covers the smallest subset of functions. The middle
level (level 1) covers a larger subset and the highest level
(level 2) covers all the available functions. The access level
is associated with a user account by specifying a role for
the user. See Table 4.18 "User roles in the A7 MIG Welder
system" for descriptions of dierent user roles and the
associated access levels.
User accounts are protected from unauthorized use by a
PIN code. The PIN code is a 4-digit numeric code that can
have any value between 0000 and 9999. Each user can
change their PIN code. Administrator level users can reset
the PIN codes of other users. The user identication system
requires at least one existing administrator level user
account in order to work correctly. The system prevents
deleting or changing an administrator user account when
no other administrator account exists.
In the initial state, there is only one user account called
Admin in the system. The PIN code of the Admin user is
‘0000’ (four zeroes) by default.
Table 4.18 User roles in the A7 MIG Welder system
Role Access level Description
Welder Level 0 A welder works on a robot cell changing workpieces and welding. The welder can
adjust welding values within the limits set by the supervisor.
The welder cannot change system settings or memory channels.
Supervisor Level 1 A supervisor teaches the robot new works and prepares the system for welding. The
supervisor species welding value limits to be used by welders. The supervisor creates
memory channels and deletes and modies them.
The supervisor cannot change the system settings related to the cell conguration.
Administrator Level 2 An administrator builds and maintains the robot cell. The administrator species all
system settings related to the xed environment, for example, emergency stop or
welding cable length. The administrator can create, modify and delete other users and
set user identication system o if needed.

OPERATING MANUAL
4.5 Touch sensor (seam search)
The touch sensor is a specic functional system used in
automated welding for finding workpieces accurate
location and position. The touch sensor hardware and I/O
are located in the robot interface unit. A welding robot
nds the particular edges of the workpiece by touching
them either with a welding wire or a gas nozzle. Touches
are detected by the touch sensor and the information is
passed on to the robot controller.
The touch sensor generates a sensing voltage separately
from the welding power source. Touch is detected when
there is a short-circuit between the workpiece and the
sensing tool resulting in a voltage drop. The negative pole
of touch sensor’s voltage source is connected to a welding
minus. The positive pole of the sensor is connected either
to a welding plus or a gas nozzle. The target for the positive
pole can be changed by a user. A relay in the touch sensor
device enables the conguration by software.
The touch sensor system consists of hardware and
software. The hardware consists of a touch sensor device, a
fast status output connector and wiring in the wire feeder’s
control cable for the gas nozzle use (see Figure 4.20 "Touch
sensing system"). The software enables conguration and
control. Conguration is available in the setup panel and
in the web user interface. The touch sensor is controlled by
the welding robot using the digital robot interface.

A7 MIG Welder© Kemppi Oy 2018 1824
OPERATING MANUAL
4.5.1 Voltage source, levels and safety
The touch sensor provides eight software selectable DC voltage levels (see Table 4.19,
Voltage levels”). The voltage level can be congured in the web user interface or the
setup panel. See Subsection 4.5.5, “Selecting output voltage for more information on
the voltage level setup.
All levels have limited continuous power supply to ensure human safety. The 200 V
supply drops down under the 113 V level when loaded by a 5.6 kΩ resistor which is the
nominal DC resistance of the human body. In some cases, voltage levels above 113 V can
still cause minor harm, such as pain, to a person. Use the gate door safety switch with
touch sensor levels above 110 V.
The welder system features an arc measurement function which is performed between
the welding plus and minus poles near the welding arc using specic cabling and a
measurement circuitry. The measurement system inuences touch sensing when
the welding wire is used as a touch tool and when the arc measurement cables are
connected. The measurement system does not inuence touch sensing when the gas
nozzle is used as the touch tool.
The touch sensing is inuenced when
the arc measurement cable between the power source and the wire feeder
(included in the cable set) is connected, but the arc measurement clamp from
the wire feeder to the workpiece is disconnected.
the clamp is also connected. This situation is more harmful because it causes
false touch detection at certain voltage levels.
The Table 4.19, Voltage levels” describes all setups and their relative voltage levels. The
accuracy of all values in the table except the nominal voltage is ±5 %.

OPERATING MANUAL
4.5.2 Touch tool
Two alternative touch tools can be used for touch sensing
(see Figure 4.21, Welding wire used as touch tool” and
Figure 4.22, “Gas nozzle used as touch tool”). The regular
tool is the welding wire (welding plus). Sometimes the
welding wire is not accurate enough. The tip of the welding
wire can bend resulting in incorrect position information.
In that case the gas nozzle can be used instead. Using the
gas nozzle requires extra wiring from wire feeder’s 10-pole
peripheral connector (pin F) to the gas nozzle.
The touch tool can be forced by the conguration in both
the web user interface and the setup panel, or the selection
can be allowed to be managed by the robot controller by
using the digital robot interface. See Subsection 4.5.6,
“Conguring touch tool” for more information on these
alternatives.

Figure 4.22 Gas nozzle used as touching tool
4.5.3 Fast status output
The fast status output is a direct hardware output for sys-
tems where the latency between the sensing and the de-
tection status reception is an issue. The normal latency is
around 10 milliseconds through the eldbus. The response
time of the fast output is about 1.5 milliseconds.
See the A7 Welder Integration guide for connecting and
conguring the fast output.
4.5.4 Selecting output voltage

4.6 Through Arc Seam Tracking (TAST)
Through-Arc Seam Tracking (TAST) is used in arc welding
for following a welding groove automatically by weaving
the welding head (see Figure 4.23, “Weaving the welding
head during TAST) and measuring the arc length. The
seam tracking provides precise welds in setups where the
workpiece position within repetitive tasks varies, or when
the route of the groove is complicated.
Figure 4.23 Weaving the welding head during TAST
The arc length depends on the wire tip distance from the
middle of the groove. Weaving the welding head between
the edges of the groove generates a signal that is directly
proportional to the arc length (see Figure 4.24, “TAST
signal waveform). The generated signal is equivalent to
the welding current.
Arc length
Time
1 2 3
Figure 4.24 TAST signal waveform
1. Short arc (edge)
2. Long arc (middle)
3. Short arc (opposite edge)
The welding power source measures welding current as a
contiguous value during welding. It lters the raw current
value to generate a stable signal for the TAST. The TAST
signal is valid for all MIG/MAG processes including Pulse
MIG and Double Pulse MIG.
The TAST signal is passed to a welding robot as a numeric
value using the digital robot interface. Using the TAST
requires use of certain I/O tables containing a eld for the
TAST value and the control signal. See the A7 MIG Welder
Integration guide for more information.
The TAST function is always available in the digital
robot interface and therefor it does not have any
conguration parameters in the web user interface or in the
setup panel.

4.7 Collision sensor
For information on connecting and conguring the collision sensor, see the A7 MIG
Welder Integration guide.
The collision sensor is a module mounted between a robot arm and a welding torch.
It protects the torch neck from bending and breaking on collision to an obstacle. The
collision detection is usually based on micro switches or optical switches which act on the
collision. The information about the detection is passed to the robot that uses it to stop
motion immediately to prevent any damage.
In the A7 MIG Welder the collision sensor signal is read by the wire feeder and the
information is passed to the robot by the welding system. In addition, a collision causes
always the Error 53 Collision detected in the welding system. When the error occurs, the
power source stops welding immediately.

4.10 Gas flow sensor
The welding system is equipped with a gas ow sensor that is located inside the wire feeder.
The sensor is capable of sensing gas ow for any mixture of six base gases containing
Argon (Ar), Carbon dioxide (CO₂), Nitrogen (N₂), Hydrogen (H₂), Oxygen (O₂) and Helium
(He). The gas ow sensor provides both ow indication and ow rate outputs. The outputs
can be monitored in the web user interface and in a robot pendant through the digital
robot interface.
These instructions and specications apply to a gas ow sensor unit that is a bus-
controlled standalone device inside the wire feeder. They do not apply to an integrated gas
ow sensor that uses wire feeder hardware. To check the type of the gas sensor in use, go to
setup panel’s Main menu > System cong menu > Device information and navigate through
the list. The standalone gas ow sensor device appears in the list as Gas sensor unit”. If that
entry does not exist, the system uses the integrated gas ow sensor.

4.10.3 Gas mixture setup
Knowing the exact mixture of the shielding gas is necessary for precise gas ow
measurement. The gas ow sensor unit supports ow measurement for any mixture of
the six base gases, including pure base gases. The mixtures are set up by specifying the
percentage of each gas in the mixture.
Recongure the mixture every time when the type of the shielding gas is changed.
The percentage of Argon is changed automatically when adjusting other gases, the
total percentage being always 100 %. For example, if Carbon dioxide is increased from 0 to
18 %, Argon is changed automatically from 100 to 82 %. This applies for Ar+18CO₂ gas. If
Carbon dioxide is increased to 100 %, Argon is decreased to 0 %. This applies for pure CO₂
gas, etc.

6. OPERATION DISTURBANCES
Should you experience a malfunction from your machine,
please consult the basic troubleshooting text above rst,
and complete some basic checks.
If the machine malfunction cannot be corrected with
these measures, contact your Kemppi maintenance ser-
vice workshop.
Operation of the overload protection
Yellow thermal protection lamp is lit when the thermostat
is operating, due to loading beyond the stated duty cycle.
The thermostat will operate, if machine is continuously
loaded over rated values or cooling air circulation is
blocked.
Internal fans will cool the machine, and when the pilot
lamp is not lit the machine is automatically ready for wel-
ding.
Control fuses
Fuse, 6.3 A delayed, on the rear wall of the machine provi-
des protection for auxiliary devices.
Use the same type and rating of fuse as marked beside the
fuse adapter. Damage caused by incorrect fuse selection is
not covered by the guarantee.
Under- and overvoltages in the mains supply
Primary circuits of the machine are protected against
sudden, transient overvoltage. The machine is designed
to withstand 3 x 440 V voltage continuously. Ensure that
voltage is kept within this permissible limit, especially
when the mains supply is provided by a combustion en-
gine generator. If the mains have undervoltage (under ap-
prox. 300 V) or overvoltage (over approx. 480 V) machine
control stops operation automatically.
Loss of a phase in the mains supply
Loss of a mains power phase causes noticeably poor wel-
ding properties. In some cases, the machine won't start at
all. Loss of a phase can be due to following:
Blowing of mains supply fuse
Defective mains cable
Bad connection of mains power cable on
machine terminal block or plug of machine.

7. MAINTENANCE
When considering and planning routine maintenance,
please consider the frequency of machine use and the
working environment.
Correct operation of the machine and regular mainte-
nance will help you avoid unnecessary downtime and
equipment failure.
Disconnect the machine from the mains before
handling the electrical cables.
7.1 Daily maintenance
Check the overall condition of the welding gun. Remove
welding spatter from the contact tip and clean the gas
nozzle. Replace worn or damaged parts. Only use original
Kemppi spare parts.
Check the condition and connection of the welding circuit
components: welding gun, earth return cable and clamp,
sockets and connectors.
Check the condition of the feed rolls, needle bearings
and shafts. Clean and lubricate bearings and shafts with a
small quantity of light machine oil if necessary. Assemble,
adjust and test function.
Check that the feed rolls are suitable for the ller wire you
are using, and that their pressure adjustment is correct.
7.2 Periodic maintenance
Periodic maintenance should only be carried out by
a suitably qualied person. Disconnect the plug of the
machine from the mains socket and wait about 2 minutes
(capacitor charge) before removing the cover plate.
Check at least every half year the electric connectors of
the machine – clean any oxidized parts and tighten loose
connections.
You must know the correct tension torques values
before starting the reparation of the loose joints.
Clean the inner parts of the machine from dust and dirt
e.g. with a soft brush and vacuum cleaner. Also clean the
ventilation net behind the front grill.
Do not use compressed air, there is a risk that the dirt will
compact even more tightly into gaps of cooling proles.
Do not use pressure washing devices.
Only an authorized trained electrician should carry out
repairs to Kemppi machines.
7.3 Service shop maintenance
Kemppi Service Workshops complete maintenance ac-
cording to their Kemppi service agreement.
The major points in the maintenance procedure are listed
as follows:
Cleaning of the machine
Checking and maintenance of the welding tools
Checking of connectors, switches and
potentiometers
Checking of electric connections
Checking of mains cable and plug
Damaged parts or parts in bad condition are
replaced by new ones
Maintenance testing.
Operation and performance values of the
machine are checked, and when necessary
adjusted by means of software and test
equipment.
Software loading
Kemppi Service Workshops can also test and load rm-
ware and welding software.
