6. Reverse Connection: The earth clamp to the "-" polarity, and the electrode holder to the "+"
polarity.
7. Choose the appropriate connection based on the job to be done. Improper connection will cause
an unstable arc, more spatter, and clumping. If such problems occur, change the polarity.
8. Make sure your power supply is the correct voltage for this machine or is within the allowable
range.
9. The machine is now ready for start-up.
7. OPERATING INSTRUCTIONS.
Turn on the machine by pushing the start switch to the ON position, the display will show the set welding
current intensity and the fan will start to run. Adjust the welding current intensity according to the work
to be done.
ELECTRODE WELDING PROCESS.
The electric arc increases the temperature of the materials to their melting point, allowing the electrode
to provide the material that, when melted, attaches to the metal pieces to be welded.
During the process, the coating of the electrode generates a gas that stabilizes the current arc, protecting
the welding from contamination, and is deposited as slag on the weld bead.
EXECUTION OF WELDING WITH COATED ELECTRODE.
After having made all the necessary electrical connections, both the power cable and the welding cables,
and having selected the electrode diameter and current intensity, proceed as follows:
9. Electrode
10. Coating
11. Nucleus
12. Electric arc
13. Protective gas
14. Melted metal
15. Slag
16. Weld bead
Fix the uncoated end of the electrode in the electrode
holder and connect the ground clamp to the piece to be
welded, always ensuring poper electrical contact. Cover
your eyes and face with the protection screen and try to
rub the tip of the electrode on the piece to be welded,
following a movement as if you wanted to light a match;
This is the most correct method to generate the arc.
Replace the electrode when its tip is only 2-3 cm away
from the electrode holder.
