UTP 614 Kb unalloyed, fine grained and low alloyed steels
Classifications basic coated stick electrode, AC-weldable
EN ISO 2560-A AWS A5.1

Characteristics and field of use
UTP 614 Kb is a double coated stick electrode with a universally suited application field. It is
used in industry, trade, as well as in production and repair welds for diverse base materials.
Due to a special coating formula UTP 614 Kb shows a smooth and finely rippled weld seam,
a stable arc, easy slag removal, and a very slight increase of the weld, as well as a notchfree
seam. The weld metal is little affected by steel impurities. Due to the double coating the
stick electrode is excellently suited for root- and out-of-position welding. Recovery 120%,
H2 content < 8 ml/100g.

Welding instruction
Ignite the electrode and stay at the ignition point until the electric arc is fully stabilised. Keep
a short arc during the welding process. Hold stick electrode vertical to the weldment with
slight weaving. Re-drying: 2 – 3 h at 250 – 300 °C. Only use dry stick electrodes
