- Switch the Inverter on. The two leds on the front panel will be respectively
the green = lit and the yellow = off. The green led will glow if the input voltage
is
beyond the nominal values. The yellow led will blink in case of thermostatic
protection intervention. Select the stick welding through the switch placed on the
front panel (in the units fi tted with).
- Protecting your face with a mask or a helmet. Touch, with the elctrode fastened,
in the electrode holder, the work piece until the arc will be struck.
Avoid hammering the work piece with the electrode since it may loose the
coating and increase the arc stricking diffi culties.
- After stricking the arc keep feeding the electrode into the weld pool with an angle of
about 60° and moving left to right so that you may control visually the welding. The
length of the arc can laso be controlled by lifting or lowering slightly the electrode.
Also a variation of the welding angle may increase the size of the weld pool
- Connect the earth cable to the negative pole of the Inverter and the earth clamp
to the workpiece.
- Connect the welding cable to the positive pole of the Inverter.
- Select the welding current using the potentiometer on the front panel. the welding
current should be choosen following the instruction given by the electrodes
manufacturer on the elctrode box, but the following indications may be useful as

General informations
The electric arc may be described as a source of bright light and strong heat;
in fact, the fl ow of electric current in the gas atmosphere which surrounds the
electrode and the workpiece determines the radiation of electromagnetic waves
that can be peceived as light and/or heat depending on their wave length. At an
unperceivable level, the arc also produces ultra-violet and infra-red light; ionizing
rays have never been noted. The heat produced by the arc is used in the welding
process to melt and join metal parts. The necessary electric current is supplied by
special equipment commonly called welding machine.
