3.3 WELDING WITH COATED ELECTRODE
When welding with coated electrode we must connect the electrode-holder clamp (F) and the
earth clamp (G) according to the polarity advised by the electrode manufacturer.
Normally, the majority of the electrodes must be placed with Direct polarity, that is, the
welding electrode-holder clamp in the negative pole and the earth clamp in the positive pole.
However, welding with basic or special electrodes is usually carried out with reverse polarity, that
is, the electrode-holder clamp in positive pole and the earth clamp in negative pole. We will
follow the electrode manufacturer’s instructions in each case.
This equipment includes Hot Start, Arc Force and Anti-Sticking functions. Electrode welding is
easier and more effective using these.
