Correct Electrode SelectionChoose the right electrode for the type of metal and welding process (e.g., mild steel, stainless steel).Proper Current Setting (Amperage)The correct amount of current ensures proper fusion. Too high or too low can cause defects.Right Arc LengthArc length should be short but steady. Too long makes the weld weak; too short causes sticking.Correct Travel SpeedMove the electrode steadily. Too fast = weak weld; too slow = too much heat and spatter.Clean Work SurfaceRemove rust, oil, paint, or dirt. A clean surface helps the weld to penetrate better and hold strong.
