TION GUIDE

3.3  Power source

Place the machine on a sturdy, level surface that is dry 

and will not allow dust or other impurities to enter the 

machine’s cooling air flow. Preferably, situate the machine 

in a suitable carriage unit so that it is above floor level.

•  The surface inclination may not exceed 15 

degrees.

•  Ensure the free circulation of cooling air. There 

must be at least 20 cm of free space in front 

of and behind the machine for cooling-air 

circulation.

•  Protect the machine against heavy rain and direct 

sunshine.

  Do not operate the machine in the rain.

  Never aim the spray of sparks from a grinding machine 

toward the equipment.

The power plug

The power source comes without a plug for connection 

to the electrical grid. Attach a plug suitable for your 

power-supply standard to the power cable. Check the 

connections, attach the plug to a socket, and switch the 

electrical power on from the welding power source to 

verify that the machine works properly.

  Switch the machine off, and unplug it from the power 

socket before continuing to further steps in the hardware 

installation.

  If local or national regulations specify that an 

alternative power cable is required, the cable must be 

replaced in conformity with the regulations. Connection 

and installation of the power cable and plug should be 

carried out only by a suitably qualified person. 

Remove the machine’s left-hand cover plate to enable 

attachment of an electrical cable. The power source unit 

can be connected to a 400 V, 3~ power supply.

If changing the power cable, take the following facts 

into consideration:

•  The cable enters the machine through the inlet 

ring on the rear panel and is fastened in place 

with a cable clamp (05). 

•  The phase conductors of the cable are coupled to 

connectors L1, L2, and L3.

•  The protective ground line, colored green and 

yellow, is coupled to the marked connector.

•  If you are using five-lead cable, do not connect 

the neutral conductor.

 In S-type cables there is a protective grounding conductor, 

green-and-yellow striped.

3.4  Cooling unit

If you use a water-cooled welding torch, you need a 

cooling unit installed as part of the welder system. Attach 

the cooling unit to the power source. See the detailed 

installation instructions in the operating manual delivered 

with the cooling unit package.

The cooling hose connections are described in 

Subsection 

3.8.5, “Cooling hoses.”

  The wire feeder has no connectors for cooling hoses. 

Use a special adapter to connect the cooling hoses to the 

welding torch cooling connectors.

3.5  Wire feeder

Use a two-part mounting bracket to mount the wire 

feeder securely on the robot arm. Fasten the upper part of 

the bracket to the bottom of the wire feeder and the lower 

part to the robot arm. Finish the installation by putting the 

bracket parts together and fixing them in place with bolts. 

See the illustrated instructions included in the product 

delivery package.

Mounting brackets are available for the most commonly 

used welding robots. See the complete list at

.

The wire feeder connections are described in 

Section 3.8, 

“Interconnection cable set.”
