3.2.2 Calibrating arc voltage
X8 MIG Welder measures the voltage of the welding arc and the voltage loss in the interconnection cable and welding
gun. After calibration, the power source calculates the arc voltage, if the voltage sensing cable is not connected.
Figure: Calibration of the welding cables:
Proceed as follows:
1.
Ensure that the measurement cable connects the wire feeder and the power source.
2.
Connect the voltage sensing cable from the wire feeder to the welding piece.
3.
Adjust the welding parameters.
4.
Weld for at least 4 welds of 5 seconds.
>> With several welds, the measurement result is more accurate.
>> The welder calibrates to the length of the interconnection cable. The values are saved, so you only need to cal-
ibrate once after installing the welder package.
5.
After the calibration, you can view arc voltage on Control Pad and the wire feeder control panel during and after
welding. To view the arc voltage on Control Pad display, select Voltage display mode. Arc voltage is the default
setting.
It is recommendable to keep the voltage sensing cable connected at all times. However, if the cable is not connected,
the power source calculates the arc voltage according to the calibrating values.
Repeat steps 1-4 every time you change the length of the interconnection or earth return cable.
3.2.3 Connecting to Kemppi cloud services
To use the Kemppi cloud services, connect the welding machine to the Internet either through a WLAN or a wired con-
nection. Form the connection by using the Cloud services view in the View menu. You can also see the status of the
Cloud services there.
Cloud communication requires that your network firewall allows outbound data through ports 80 (HTTP), 123 (NTP),
443 (HTTPS) and 8883 (Secure MQTT).
Kemppi cloud services include, for example, My Fleet and WeldEye.
For more information on My Fleet, see
page 8. For more information on operating Control Pad, see "Control Pad" on page 60.
