Eagle 194 MIG Cast Iron Welding Wire | Fully Machinable Nickel MIG Wire

Eagle 194 MIG is recommended for:

Thin cast iron sections
Cast iron repair
Build-up on large castings
Joining thin cast iron to steel
Repairs where minimum heat input is important
Repairs requiring machining after welding
Maintenance and industrial repair
Overlay on lower-grade steels for corrosion protection

It can also be used as an overlay where protection from wet or dry corrosive material is required.

Remove defects and surface contaminants thoroughly.
Prepare a U-type groove where required to help reduce root-pass cracking.

Preheat castings to approximately 500°F–800°F and maintain temperature while welding.

For build-up, use approximately a 1/4" arc length with a slow travel speed.

Use short beads and move frequently around the repair area to avoid excessive heat build-up in one location.

Peening is recommended. Allow the cast iron to cool slowly for best results.

Eagle 194 MIG is a commercially pure nickel, all-position wire designed to produce soft, porosity-free cast iron weld deposits.

Its approximately 150–160 BH hardness allows the finished weld to be machined, drilled, tapped and filed.

Why Eagle 194 MIG?

Fully machinable deposit — ideal where the finished repair needs machining.

Commercially pure nickel — provides a soft, workable cast-iron weld deposit.

Low-heat repair capability — especially useful on thin castings and applications where heat input needs to be controlled.

Excellent bonding — useful for joining thin cast iron to steel where lower tensile strength is acceptable.

Build-up capability — well suited for restoring large castings.

194 MIG or 194 Stick?

Choose Eagle 194 MIG when you want the productivity and continuous feeding of a MIG process with a soft, commercially pure nickel deposit.

Choose Eagle 194 Stick when you want a portable stick-electrode option for fully machinable cast-iron repair.
In simple terms:

194 MIG = continuous-wire machinable cast iron repair
194 Stick = portable machinable cast iron repair
