Z-shaped, semi-circle or stutter-step pattern. Limit side-to-side
motion to two and a half times the diameter of the electrode core.
To cover a wider area, make multiple passes or stringer beads.
When welding vertical up, focus on welding the sides of the joint
and the middle will take care of itself.

NOTE:
It is recommended that you try welding and rate of
welding current first on something else than the actual work piece.
You can start welding after having made the necessary selections.
Arc is lit by scratching the welding piece with electrode. Length of
arc is regulated by holding electrode tip at a suitable distance
from welding piece. Suitable arc length is usually about half the
diameter of the electrode wire.
