THIS IS A DUAL SHIELD CORED WIRE
Nickel 55 (ENiFe-Cl) welding electrode is
designed for welding gray iron castings to
themselves as well as joining them to mild
steel. It can also be used to repair castings.
The welds are moderately hard and require
carbide tipped tools for post weld machining.
A preheat and interpass temperature of not
less than 350ºF is recommended during
welding.

ERNiFe-CI (aka ERNI55) is a filler metal used for TIG and MIG welding of cast iron. It is also used to repair castings. The weld metal of ERNI55 is harder than that of ERNI99. A preheat and interpass temperature of 350 deg F minimum is recommended during welding, without which the weld and heat affected zones may develop cracks.
