3.2. OPERATIONS SEQUENCE FOR STARTING UP THE EQUIPMENT.
1.- Prepare the equipment according to the welding process to be performed. From section 3.3. onwards of this
manual you will find the equipment preparation diagram according to the work you wish to carry out.
2.- Connect the plug to the mains and apply the main switch A for start-up.
3.- By means of working mode push-button 1, selects the desired welding mode MMA (Electrode) or TIG.
4.- Adjust the desired welding current using the potentiometer C, and visualize it by means of display G.
5.- You can now start the welding operation.
3.3. WELDING WITH COATED ELECTRODE.
By means of push-button 1 the coated electrode MMA welding mode has been selected.
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 straight 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. Equipment preparation for the working mode is drawn in the figure; in this
case, observe that the polarity used is inverse, meaning that the welding electrode-holder is connected to the positive
pole.
