Arc speed:
Because the electrode is melted continuously into the weld, it is important to continue feeding the electrode accordingly. However, this must be done at the right speed. When the travel speed is too fast, the resulting
bead is narrow and penetration is poor. When the speed is too slow, the bead is high and wide and the metal tends to overheat.
Overheat protection:
The unit will automatically shut down once the duty cycle is reached. Ensure proper air flow in/out of the vents of the machine to avoid premature overheating. The unit should have enough unobstructed air space
around it at all times.
Passes:
Sometimes, more than one pass is necessary in order to obtain a strong weld. You should ensure that any slag is removed from the weld and that the metal is properly cooled after performing subsequent passes.
Quality of the bead:
The graphic below provide guidelines to evaluate the weld based on the appearance of the weld bead.
