Thermal Protection - Cebora SOUND MIG 1660/M ALUMINIUM Manual De Instrucciones

2.3.2 Mechanical protection (safety button)
When the movable side is opened, this activates the safety
button which prevents operation of the welding machine.
This protection, indicated when the LED A is lit, avoids
hazardous situations when the operator replaces the roller of
the wire feeder unit or the welding electrode.

2.3.3 Thermal protection

This machine is protected by a thermostat, which prevents
the machine from operating if the allowable temperatures are
exceeded. Under these conditions the fan keeps running
and the LED A lights.
3 INSTALLATION
Make sure that the supply voltage matches the voltage indi-
cated on the specifications plate of the welding machine.
Mounting a plug with an adequate capacity for the supply
cable, making sure that the yellow/green conductor is con-
nected to the earth pin.
The capacity of the overload cutout switch or fuses installed
in series with the power supply must be equivalent to the
absorbed current I1 of the machine.

3.1 Setup
The machine must be installed by skilled personnel. All con-
nections must be carried out according to current regula-
tions, and in full observance of safety laws (regulation CEI
26-10 - CENELEC HD 427).
3.2 CONTROLS ON THE FRONT PANEL.
A- LED yellow.
Lights when the thermostat or safety button interrupt opera-
tion of the welding machine.
B- Setting knob.
• Adjusts the welding wire speed when using manual pro-
grams.
In this condition the display G indicates only the current
during welding.
• When using synergic programs, it allows you to preset the
current and adjust during welding. The current is indicated,
in all conditions, by the display G.
During welding, this current may vary (although only slightly)
based on the thickness of the material and the manual skill
of the operator. It is essential to use the R key to select the
correct welding program so that the display G indicates the
correct preset current value.
