Connect The Second Wire Feeder; Powering Up - Kemppi A7 350 Integration Manual

3.13.2 Connect the second wire feeder

Connect the interconnection cable of the second wire feeder to the weld+ connector in
the front panel of the power source. Connect the control cable of the second wire feeder
to the extension connector in the back panel of the robot interface unit. Switch the power
source on and test the wire feeders by performing a wire feed test for both wire feeders.
Selecting the wire feeders from the setup panel or web user interface for the test.
In water-cooled systems with two water-cooled torches the cooling water circulation
must be equally distributed into both torches. It is recommended to connect the torches in
serial. In parallel the water flow can differ between the torches and may cause damage to the
torch. The extension kit includes support for water valves. Should you want to use valves to
control the circulation, please contact Kemppi service for instructions and guidance.
Only one wire feeder can be used for arc voltage measurement at the time. Do not
branch the arc measurement cables.

3.14 Powering up

Before powering up the welding system, check all cable connections.
Attach the power plug to an electrical socket, and switch the machine on. Check that
the machine starts up properly. The setup panel boots up within 10 seconds. The Web
UI is usually accessible in 30 seconds.
The Web UI access time depends greatly on the network configuration in use. The
fastest configuration is a direct connection with fixed IP addresses. With a local area
network and DHCP, the access time can be significantly longer.
