diamondspark NiCu1 RC is a seamless, weather resistant flux-cored wire of the rutile type, alloyed with copper and nickel.
It joins materials such as S235JRW and ASTM A 588. The seamless make limits moisture pickup by the core and keeps the hydrogen level in the weld low, and the wire is used on steel structures, tanks, machine frames and workshop work on black steel.
- Classification EN ISO: 17632-A T 46 4 Z P M21 1 H5
- AWS classification: A5.29 / SFA-5.29 E81T1-WGM H4
- Shielding gas: M21
- Diameters: 1.0 / 1.2 / 1.4 / 1.6 mm
Clean rust, paint and grease out of the groove, contaminated plate gives porosity even with well set parameters. Store the wire dry and do not leave an open spool in the feeder overnight, the core takes up moisture. Do not shorten the stick-out too far, a flux-cored wire needs resistive preheating so the core melts in time.
