6.4 MMA-welding
Connection of welding and return cable
The welding power source has two terminals, one plus and one minus pole, for the con­
nection of the welding and the return cable. Connect the welding cable to the pole indi­
cated on the package of the electrode to be used.
Connect the return cable to the other terminal. Fit the earth clamp of the return cable
to the work-piece and make sure there is good contact between the work-piece and the
return cable terminal on the welding power source.
6.5 Overheating protection
The power source has two thermal overload trips which operate if the internal
temperature becomes too high. A fault code is shown in the panel. They reset
automatically when the temperature has fallen.
6.6 Turning on the power source
Turn on the mains power by turning the mains switch to the ”1” position.
Turn the unit off by turning the switch to the ”0” position.
Whether the mains power supply is interrupted or the power unit is switched off in
the normal manner, welding data will be stored and is available next time the unit is
started.
7 CONTROL PANELS
When mains power is supplied the unit runs a self diagnosis of the
LEDs and the display, the program version is displayed and in this
example the program version is 0.18.
VRD (Voltage Reduction Device)
The VRD function ensures that the open-circuit voltage does not exceed 35 V when
welding is not being carried out. This is indicated by a lit VRD LED. The VRD
function is deactivated when the system senses that welding has started.
If the VRD function is activated and open-circuit voltage exceeds the 35 V limit, this
is indicated by an error message (16) appearing in the display and welding cannot
be started whilst the error message is displayed.
NOTE! The VRD function is not active (LED has gone out) on delivery. Contact an
authorised ESAB service technician to activate the function.
