Kemppi KempArc Pulse TCS [12/38] Enabling tandem control system

2.11 ENABLING TANDEM CONTROL SYSTEM

The KempArc Pulse TCS welding system is equipped with a Tandem Control system (TCS),

which allows both ller 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 dierent 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 eects.

For correct connection and conguration 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 ller wire to the rst contact tip of the tandem welding gun..

2. Attach the other end of the welding cable to the wire feeder, which delivers ller 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 ller 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 ller 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.
