Anti-Stick Function; Mains Connection; Application Limitations - REHM BOOSTER 140 Instructions De Service

When the welding work begins, the Booster 140 supplies for a short time a higher current
than the welding current selected (max. 140A). This ensures good ignition and a steady arc
very quickly.
3.2.2 Arc Force
During the welding work, the Booster 140 monitors the welding current and the welding
voltage. If the Booster 140 detects that a droplet transfer takes place in a short-circuit, it
supplies for a short time a higher current than the welding current selected (max. 140A) in
order to quickly eliminate this short-circuit. As a result, the Booster 140 prevents failure or
sticking of the electrode during welding.
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).

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.

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
