The suggested electrode and welding rod angles for welding a bead on
plate are shown above. The same angles are used when making a butt
weld. The torch is held 60–75° from the metal surface. This is the same
as holding the torch 15–30° from the vertical.
Take special note that the rod is in the shielding gas during the
weldingprocess.
