Cuation: The indicators will light at overloading only.
Thermal protection is provide on the unit to switch off the
welding current supply automatically as soon as the inner
temperature. As it drops to a value of correct operation, the
unit switches on again.
Step-by-step Instructions
The welding area should be free of any rust and varnish. The
electrode is selected by the type of material. It is
recommended to test the electrode and the current intensity
on scrap at the beginning. Place the electrode ca 2 cm above
the starting point. Always use a welding shield, welder's
gloves and protective clothing. Touch the piece and slightly
pull the electrode.
Wrong
(arc too long)
Precise length of the arc is critical as the current and voltage
intensity varies. Poor intensity of current makes both the weld
and resistance worse. The electrode angle support should be
70-80 degree forward with regard to the piece worked. Too
big angle makes the slag slide under the edging material. If
the angle is too small, the arc will fluctuate and splash. In
either of the cases the wells is porous and weakened
Wrong Wrong
The slag should not be removed before the weld gets cooled.
Continue welding of an interrupted weld after the slag is
removed.
Wrong
The welder should try to keep the arc length constant. As the
electrode gets worn, it should typically get nearer. It is
recommended to remove the electrode in the direction of the
weld to avoid forming a porous crater.
