Description Of Protective Devices; Thermal Protection; Motor-Driven Generators; Protection Against Short-Circuits (Antistick) - Cebora 506 Bedienungsanleitung

SMAW Suitable for welding with covered electrodes.
TIG Suitable for TIG welding.
U0. Secondary open-circuit voltage X.Duty cycle percentage. % of 10 minutes during which the welding ma-
chine may run at a certain current without overheating.
I2 Welding current
U2. Secondary voltage with current I2
U1. Rated supply voltage
1~ 50/60Hz 50- or 60-Hz single-phase power supply
I1 max. This is the maximum value of the absorbed current.
I1 eff. This is the maximum value of the actual current absorbed, considering the duty cycle.
IP23S Protection rating for the housing.
Grade 3 as the second digit means that this equipment may be stored, but it is not suitable for use outdoors
in the rain, unless it is protected.
S
Suitable for hazardous environments.
Note:
1- The machine has also been designed for use in environments with a pollution rating of 1. (See IEC 60664).
2- This equipment complies with IEC 61000-3-11 provided that the maximum permissible system impedance
Zmax is less than or equal to 0,249 (art.520) - 0,362 (art.506) at the interface point between the user's supply and the
public system. It is the responsibility of the installer or user of the equipment to ensure, by consultation with the dis-
tribution network operator if necessary, that the equipment is connected only to a supply with maximum permissible
system impedance Zmax less than or equal to 0,249 (art.520) - 0,362 (art.506).

Description of protective devices

2�3�1

Thermal protection

This equipment is protected by a thermostat. When the thermostat is tripped, the machine stops delivering current but
the fan continues to run. The yellow led (B) lights to indicate when it is tripped. Do not shut off the welding machine
until the led has gone off.
2�3�2

Motor-driven generators

These must have a power equal to or greater than 8KVA for art. 506, 10KVA for art. 520 and must not deliver a voltage
greater than 265V.
2�3�3

Protection against short-circuits (antistick)

If a short-circuit occurs lasting more than two seconds when welding with coated electrodes, the current is reduced to
harmless levels.

INSTALLATION

This must be carried out by skilled personnel. All connections must be carried out according to current regulations, and
in full observance of safety laws (regulation CEI 26-36 - IEC/EN 60974-9).
− Make sure that the supply voltage matches the voltage indicated on the specifications plate.
− When mounting a plug, make sure it has an adequate capacity, and that the yellow/green conductor of the power
supply cable is connected to the earth pin.

Description of the equipmet

A) Current adjustment. B) Yellow led (see 2.3).
C) Power ON led.
D) Output terminal (-).
E) Output terminal (+).
F) Switch.
G) Mains cable.
H) Connector (Art. 520)
I) Adjusts an overcurrent that may be inserted to aid in striking the arc. This function is active in both MMA and TIG
modes (Art. 520).
L) Adjusts an overcurrent that makes it possible to maximize transferring the electrode drop to the workpiece. This
function is not active in TIG welding (Art. 520)
