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
st
manual you will find the equipment preparation diagram according to the work you wish to carry out.
2 . Connect the plug to the mains.

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 straight polarity; that is, the welding electrode-holder
clamp in the negative pole and the earth clamp in the positive pole.
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.

3.4 WELDING USING THE TIG PROCEDURE WITH MANUAL GAS AND LIFT ARC CONTROL.
In TIG welding we must only use straight polarity, placing the welding torch in the negative pole. Additionally, a
bottle of gas M (normally Argon) should be located at the installation, which we will connect to the machine through a
pressure reducing valve N, as indicated in figure below.
