LT·E4313 2.0/2.5/3.2/4.0/5.0 mm Carbon Steel Electrodes
Conform to Standard
Purpose:It is suitable for welding structures made of low carbon steel,
performs very well in welding thin and small size steel plates and
also has very good performance in the situation that requires nice
and clean bead appearance.
Specification:J421 is rutile-based carbon steel electrode. It has very good welding usability that enables it to perform all-position welding, operates on AC/DC, removal of slag is easy, has stable arc and also has very good bead appearance. It is easy to operate, which makes re-striking the arc easy.
