Eagle 193 Ni99 Cast Iron Welding Rod | Fully Machinable Nickel Electrode

Eagle 193 Ni99 is recommended for:

Engine blocks
Cylinder heads
Cast iron housings
Transmissions
Gears
General cast iron repair
Build-up on cast iron
Joining steel to cast iron
Repairs requiring a machinable weld deposit
Maintenance and industrial repair

Designed for cast iron applications where softness, machinability and low heat input are especially important.

Use AC or DC Straight [–] Polarity.

Prepare and clean the weld area thoroughly. Groove out cracks and damaged material as required. Eagle 188 airless gouging electrodes may be used for weld preparation.

Use the lowest effective amperage while maintaining a short-to-medium arc length.

Make short weld deposits approximately 1"–1-1/2" long using a skip-weld technique to help minimize heat input.

Peen the weld while hot to help reduce internal stresses, and allow the casting to cool slowly.

Eagle 193 is a high-nickel Ni99 cast iron electrode designed to produce soft, fully machinable weld deposits.

Its low-heat operating characteristics help reduce thermal stress in the casting, while the high-nickel deposit provides excellent machinability and a clean, porosity-free weld.

Why Eagle 193 (Ni99)?

Fully machinable deposit — ideal where the finished repair needs to be drilled, tapped, filed or machined.

High-nickel deposit — provides a soft weld deposit suitable for precision cast-iron repairs.

Low heat input — helps reduce thermal stress in sensitive castings.

Porosity-free welds — designed for clean, dependable cast iron repair.

Versatile repair capability — suitable for cast iron repair, build-up and joining steel to cast iron.

193 (Ni99), 180 (Ni55) or 191?

Choose Eagle 193 (Ni99) when maximum machinability is the priority.

Choose Eagle 180 (Ni55) when you want a strong, machinable general-purpose cast iron repair electrode.

Choose Eagle 191 when the casting is dirty, oil-soaked or contaminated and machinability is not the main concern.

In simple terms:
193 Ni99 = premium machinability
180 Ni55 = strong, machinable general repair
191 = dirty/problem cast iron
