I just bought 2# spool of .035 Crown Alloys Royal 44-30 Premium Nickel-Iron-Manganese Mig Wire (ER NiFeMn-CI) to use with my Mig on some small castings that need built up. Figured i would give it a shot and take some before and after pics. The 2# spool was 75 bucks so it will be an expensive test but i have wanted to try cast and mig for 35 years. You can use CO2, Argon, or 75/25 gas and i have all 3 to try. I have some lathe parts to do then they wil be ground back to shape after filling the marks with weld. Pics tomorrow...Bob
