SUPRATHERME (MOD)

AWS: SFA 5.1 E7018 IS: 814 EB5426H3JX EN ISO CODE: 2560-A E 42 3 B 3 2 H5

Supratherme (MOD) is a basic coated, iron powder, hydrogen controlled, all conventional position electrode, produces radiographic quality welds, having excellent cracking resistance. The electrode ideally suited for welding carbon steels used in the construction of equipment subject to heavy dynamic load impact and severe service conditions in sour gas service.

Precaution

1. Ensure the electrodes are dry. Re-dry the electrodes at 250-300 C for one hour.

2. Use short arc, minimize heat input.
