▎Applications and Features

A low hydrogen coated electrode for 490N/mm2 grade steel for low temperature resistance.
Weld metal contains 1.5%Ni with good conditions of CVN obtained at -45°C.
It is suitable for Flat and H-Fillet welding.
It is ideal for welding in low temperature resistant steel of LPG storage tanks.( ASTM A537C1,JIS G3126 and SLA325A).

▎Welding Position

▎Welding Instruction

Clean up the contaminations on the steel. Keep arc as short as possible.
Dry the electrodes 350~400°C in 60 minutes before welding.
Excellent strike and re-strike capabilities with the back step method. (Please refer to Appendix A)
Please note that over welding heat input causes the poor conditions in CVN.

▎Application
