Total length (including internal part): 0,95 m

Number and cross section of wires: 5 x 1 mm2

Power plug type: ILME 16 A 230 / 400 Va.c.

Inlet for jerrycan filling.

2.3 ASSEMBLY WITH THE WELDING POWER SOURCE

DANGER!

Lifting and positioning

Read the warnings highlighted by the following symbols in the

“General prescriptions for use”.

Set the welding power source ON/OFF switch to “O” (unit de-

energized).

Remove the screws from the power source cabinet.

Loosen the screws of the upper brackets of the cooler and open

out the brackets slightly.

Place the power source on top of the cooler.

Secure the cooler brackets to the power source using the

previously removed screws.

Connect the plug of the cooler power cable to the cooler power

socket on the rear panel of the welding power source.

Plug the power cable plug into a mains socket outlet.

Set the welding power source ON/OFF switch to “I” to switch on

the unit.

Set the cooler ON/OFF switch to “I” (unit powered).

WARNING!

Periodically checking the level of the liquid in the indicator on the

side of the cooling unit.

Be careful when choosing the cooling liquid: it must not be an

electricity conductor.

Do not use polypropylene liquids because they damage the seals

and generate incrustations.

Read the warnings highlighted by the following symbols in the

“General prescriptions for use”.
