REHM BOOSTER 140 Betriebsanleitung Seite 13

3.2.3 Anti-Stick function
If there is a permanent short circuit during electrode welding, the Anti-Stick function is
activated after approx. 1.0 s, limiting the current to approx. 35 A. This prevents the electrode
from burning out, and the operator can easily interrupt the short circuit by removing the
electrode from the workpiece.
3.3 "+" marking on the welding current socket
The "+" sign indicates the positive pole of the welding current source (left-hand welding
current socket)
3.4 "-" marking on the welding current socket
-
The " " sign indicates the negative pole of the welding current source (right-hand welding
current socket).
4 Mains connection
The welding unit is fitted with a protective contact plug. The unit is operated with fuses or
circuit breakers with a rated current of 16A. When the unit is switched ON, the main switch at
the back of the unit is lit up. The Booster 140 permanently monitors the power supply
voltage. If the values ascertained during operation are too high (above 260V~) or too low
(below 150V~), the unit switches itself off and reverts to a safety function. When the power
supply voltage is correct, operation can be resumed by switching the unit off and back on.
5 Installation
Care should be taken during installation of the unit to ensure that the ventilation slots are not
covered and that the installation site is suitable for Protection Class IP23.
6 Application limitations
The unit can be used in any environmental conditions corresponding to Protection Class
IP23 or lower. For welding in certain locations (e.g. stables), the Protection Class of the
welding units has to meet special requirements. The possibility of using the unit in such an
environment should be checked for each individual case. The unit is not intended to be used
for more than one shift per day.
7 Maintenance
The unit does not require maintenance. However, the condition of the electrical cables must
be checked at regular intervals
