4.4 User identification 4.4.1 Overview System configuration, 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.
4.4.3 Creating new users The user identification system can be turned on from either the web user interface or the setup panel. Setup panel Turning the user identification system on requires administrator privileges in the setup panel. Go to the Main menu > User settings and select a user with administrator privileges. Provide a valid PIN code to log in. In the User settings menu look for the User mode parameter and select the desired value (ON). Press the Save button to save the settings.
4.4.5 Changing user role 4.4.6 Changing username Deleting a user requires administrator privileges. Welders and supervisors cannot delete users. At least one administrator account is required in the system. You cannot delete your own account. When a new user is created in the web user interface, the user role is specified for the user in the same view. When a new user is created in the setup panel, the default role is Welder. The role can be changed afterwards.
4.4.9 Logging in and out, changing active user The administrator can reset a PIN code to let the user redefine it and access the system again. Resetting the PIN code requires administrator privileges. Setup panel The setup panel displays User logged off text when no user is logged in. To log in press the F2 button, select a user, provide a valid PIN code and press OK. You are now logged in. Setup panel Go to the Main menu > User settings and provide your PIN code to access the menu.
4.5 Touch sensor (seam search) 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.

Configuration (web user interface or setup panel) Welding plus (welding wire touch sensing) Wire feeder control cable (gas nozzle touch sensing) Fast status (direct hardware connection, optional) Fieldbus / Digital robot interface Arc measurement cables Peripheral connector Touch tool (welding wire or gas nozzle) Touch detection Welding minus (touch sensor ground) On/Off control The touch sensor device behaves as a software controllable power source.
4.5.1 Voltage source, levels and safety 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.
4.5.3 Fast status output 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.
4.6 Through Arc Seam Tracking (TAST) 2 3 Time Setup panel Go to the Main menu > Robot menu > Touch sensor menu and turn the control knob on the Tool parameter to configure the touch tool. Select the Welding wire or Gas nozzle to force the tool, or USER to let the tool selection control to the robot. Press the Save button to save the settings. Web user interface Go to the Welding settings > System settings > Touch sensor settings and select the touch tool by clicking one of the Touch tool buttons.
4.7 Collision sensor For information on connecting and configuring the collision sensor, see the A7 MIG Welder Integration guide. Collision sensor Fieldbus / Digital robot interface Wire feeder control cable Configuration using web user interface or setup panel Peripheral connector The collision sensor is mounted to the robot arm, and it is a mounting point for the welding torch (see Figure 4.26, “Collision sensor mounting”).
4.7.2 Selecting sensor type 4.7.3 Selecting output polarity The collision sensor can be turned on and off by using either the web user interface or the setup panel. Setting sensor on and off requires administrator privileges. The sensor type can be selected by using either the web user interface or the setup panel. Setting the sensor type requires administrator privileges. The collision sensor should be turned off by software when there is no collision sensor installed in the system.

The filler liner is a consumable part which needs to be changed if it has been worn. To load a new filler liner, follow the following instructions.
Mounting wire guide tubes and wire feed rolls to the wire feeder: 3. 4. 5. 6. 7. 8. Open the pressure handle of the wire feed mechanism. Remove the orange-colored fasteners from the motor shafts (lower shafts). Remove the shafts of the auxiliary feed rolls by pulling from the orange-colored knobs. Mount the outlet wire guide tube.

4.9 Arc measurement The welding system supports precise arc voltage, current, and power measurement for specific processes. Using this feature makes it unnecessary to concern about voltage losses in the welding cables. Measurement requires dedicated cables from the power source to the wire feeder (included in the interconnection cable set) and from the wire feeder to the workpiece (a separate cable with a clamp, included in the delivery). See Figure 4.30, “Arc measurement system” for details. 4.9.
4.10 Gas flow sensor These instructions and specifications apply to a gas flow sensor unit that is a buscontrolled standalone device inside the wire feeder. They do not apply to an integrated gas flow sensor that uses wire feeder hardware. To check the type of the gas sensor in use, go to setup panel’s Main menu > System config menu > Device information and navigate through the list. The standalone gas flow sensor device appears in the list as “Gas sensor unit”.
4.10.3 Gas mixture setup Knowing the exact mixture of the shielding gas is necessary for precise gas flow measurement. The gas flow sensor unit supports flow 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. Reconfigure the mixture every time when the type of the shielding gas is changed.

6. OPERATION DISTURBANCES Should you experience a malfunction from your machine, please consult the basic troubleshooting text above first, and complete some basic checks. 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.
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 maintenance will help you avoid unnecessary downtime and equipment failure. Disconnect the machine from the mains before handling the electrical cables. 7.2 Periodic maintenance 7.3 Service shop maintenance Periodic maintenance should only be carried out by a suitably qualified person.
9. DISPOSAL Do not dispose of electrical equipment with normal waste! In observance of European Directive 2002/96/EC on waste electrical and electronic equipment, and its implementation in accordance with national law, electrical equipment that has reached the end of its life must be collected separately and taken to an appropriate environmentallyresponsible recycling facility.
