Cast iron mig welding.
 

Cast iron mig welding.
I do lots of cast iron repairs for a few local companies and found this mig wire. Hum at 75 bucks i will try it because some of my repairs are kinda iffy with my stick welder. Well it works better than great from the 4 jobs that i have done with it. I did the exhaust manifold on my Geo Metro while still on the car and it now has 7,000 miles on the fix. I also repaired a broken bellhousing for an excavator with 2 broken bolt holes. And my neighbor has a Ford tractor with a leaky exhaust so i put one pass and built up the wore down area. He filed to suit and its now quiet. Then i had a lathe bracket with the corner hole broke out. I layed a mig tip in the hole and filled over it with wire then ground and redrilled. Looks like good stuff. I use it with Argon gas but any gas mig will work...Bob

Did you just use regular mig wire?

edit to add, where did you find the copper bolts& slugs?

Sorry i forgot the link for the wire.

Its wire made for cast iron. The copper slugs were punched from some sheets i have been hording for 30 years. The last pic just uses a regular mig gun tip in the hole then i welded over it...Bob

too cool!
How pricy is the wire?

I paid 75 bucks for a 2# spool from my lws but i have seen it online for 70...Bob
