2.11 ENABLING TANDEM CONTROL SYSTEM
The KempArc Pulse TCS welding system is equipped with a Tandem Control system (TCS),
which allows both filler wires to be controlled independently of each other. To enable the
control system, you need to connect the two power sources to each other using a tandem
control cable.
Connect tandem control cable to BROWSER/TANDEM connections on the back of the control
boxes as shown in the picture.
2.12 INTERCONNECTION WITH WIRE FEEDERS
Both power sources are connected to wire feeders with their own interconnection cable sets.
Each cable set includes the following parts:
• a welding current cable
• a control cable
• four cooling hoses, two blue ones and two red ones
• a shielding gas hose.
Kemppi provide a choice of interconnection cable sets for different environments. Only
materials that meet the demands of Kemppi's international markets are used in their
construction.
Used correctly, Kemppi cable sets ensure high welding performance and serviceability.
Before use, always ensure the cable set is in good condition and that connectors are correctly
fastened. Loose connections reduce welding performance and may result in damage to
connectors due to heating effects.
For correct connection and configuration of cable sets, please refer to overview of the system
earlier in this operating manual.
2.12.1 Connecting the welding cables
The welding cables are used for delivering the welding power to the robot's tandem welding
gun. To connect the welding cables, do the following:
1. Connect the welding cable to the plus pole (+) located on the back of the leading power
source that delivers filler wire to the first contact tip of the tandem welding gun..
2. Attach the other end of the welding cable to the wire feeder, which delivers filler wire to
the leading contact tip.
3. Connect the welding cable to the plus pole (+) on the back of the trailing power source
that delivers filler wire to the second contact tip of the tandem welding gun..
4. Attach the other end of the welding cable to the wire feeder, which delivers filler wire to
the trailing contact tip.
You can also use a manual welding gun for tack welding when necessary. It is connected to
the plus pole (+) on the front of the power source.
NOTE! Do not overload the welding cables, as an overload may cause voltage loss and
overheating.
