Connecting the welding unit

Connect the REHM welding current source in accordance with the valid VDE
regulations to the power supply network and ensure that you meet all the
regulations stipulated by the appropriate professional associations.
When connecting the unit, pay attention to the specifications regarding the supply
voltage and network fuses. Safety mechanisms and fuses must always be
dimensioned for the specified current. The required specifications can be found
on the rating label of your unit.
Always switch the unit off when it is not in use.
Screw the cylinder pressure regulator onto the cylinder and check the sealness
of the connection. Always close the cylinder valve after completed work. Observe
the regulations of the appropriate professional associations.
5.5

Cooling the welding unit

Set the REHM welding unit up in such a way that the air inlets and outlets are not
affected. The duty ratio of the power components indicated can be reached only
with adequate ventilation (see "Technical specifications"). Ensure that no sanding
dust, dust or any other metal items or foreign objects are able to enter the unit.
5.6 Guidelines for working with welding power
supplies
Welding tasks may only be carried out by specialists or trained personnel familiar
with the technology and procedures. When welding, wear protective clothing and
ensure that other people in the vicinity of the machine are not endangered. After
completing welding, leave the unit switched on for a few minutes so that the fan
runs a little longer and removes the residual heat from the unit.
5.7

Connecting welding cables or torches

The REHM WIG welding units are fitted with quick-fit socket systems for
connecting grounding cables and WIG torches or electrode cables. The
connection is made by inserting and turning clockwise. The shielding gas hose is
connected via quick connectors to the welding unit. The torch button socket is
fitted into the socket that is built in.
Important!
In order to prevent unnecessary losses of power during welding, ensure that all
connections of the welding cables are tightened and well insulated.
